ADELAIDE

Rory Atkins: Talented left-footer who performed consistently well in the SANFL last year and nearly broke through for an AFL debut. Was having a stellar pre-season until he injured his knee, which will mean a delayed start to the season.

Brad Crouch: A quickly emerging superstar, Crouch rebounded amazingly last year from an Achilles injury and then a broken leg. He is tough on the inside, polished on the outer and hasn't put a foot wrong all pre-season.

Matt Crouch: Although more as an inside midfielder at West Lakes, the younger of the Crouch brothers has no trouble getting his hands on the ball. Ankle surgery in January was a setback but he is back into full training.

Patrick Dangerfield: One of the game's brightest stars, Dangerfield's power is almost unmatched in the AFL. He's a game-winner who has recovered from a knee injury but will endure constant speculation about his future until he decides whether to stay or leave at season's end.

Richard Douglas: The 2010 winner of the Malcolm Blight Medal as the club's best and fairest, Douglas finished last year relatively strongly and has not missed a beat this pre-season. A crucial player when firing.

Cam Ellis-Yolmen: It has taken Ellis-Yolmen a number of seasons to develop but he is beginning to find the consistency required at the top level. He's a quick but big-bodied midfielder and was one of the club's best on Thursday night against Geelong with 23 disposals.

Mitch Grigg: A classy left-footer who usually makes good decisions when in passion, Grigg is entering his fourth year at West Lakes and needs to take the next step and play regular senior football.

Sam Jacobs: He benefited greatly last year from losing weight and was able to accumulate more possessions around the ground. A minor knee injury was a slight setback earlier this year but his fitness has improved and he will be ready to go for round one.

Sam Kerridge: Probably the fittest player at West Lakes and it allows him to play a variety of roles. He is good up forward, can run with players and holds his own in the midfield. A flawless pre-season has him placed to demand more senior games in 2015.

Riley Knight: A quality wingman/half-forward whose debut season in the SANFL last year almost pushed him into the senior side. Unfortunately an ankle injury has set him back and he will face a late start to the season.

Luke Lowden: After finally making his debut for Hawthorn last year the ruckman was traded to Adelaide where he needs to pressure Sam Jacobs for a place in the side. He can play up front in attack, which helps his cause.

Jarryd Lyons: Turned down offers to join a Victorian side last year to stay and his pre-season form has suggested he will throw everything at season 2015. In both NAB Challenge games he has been in the top five for Crows' possessions.

David Mackay: Has a firm grasp on the title of Adelaide's premier wingman. Is fast and has great skills on the outside. He's recovered from a minor hamstring strain, which recently robbed him of a few weeks' training.

Reilly O'Brien: The draftee ruckman impressed everyone in Adelaide's first NAB Challenge game against North Melbourne with 14 hit-outs, as well as some strong marks around the ground. Likely to spend the year in the SANFL.

Rory Sloane: A champion player who thrives on contests and lifts when the going gets tough. He is one of the club's most important players and has enjoyed a great pre-season, but is yet to re-sign with the club.

Scott Thompson: The veteran has had an interrupted pre-season because of hip surgery and more recently a hamstring injury. But his experience will help him recover quickly and as he showed last year, has got plenty left to offer.

Nathan van Berlo: Missed last year with a ruptured Achilles but has returned in the NAB Challenge this year and has his sights set on round one. He has trained fully since day one of pre-season. His on-field leadership and experience will prove hugely important in Adelaide's midfield.

Anthony Wilson: Rated the fastest player outside the AFL before the Crows drafted him, Wilson can play up on a wing or deeper in attack. He will have to develop his game before commanding regular game time in the AFL, but has taken well to a full-time football environment.

Matthew Wright: A natural footballer who has played several different roles over the years, from small forward to midfielder to tagger. Great pre-season will hold him in good stead to try to cement his place in the side. - Harry Thring

BRISBANE LIONS

James Aish: Stellar first season for the South Australian who played 21 games and averaged 18 disposals. Came with a reputation for being a quality outside ball user, but worked hard on his inside game to the point where he often started in the centre square. Polished midfielder who is out of contract at the end of 2015.

Dayne Beams: Huge off-season signing for the Lions, landing the Collingwood premiership player and Copeland Trophy winner. Beams has the perfect mix of inside ball-winning and the ability to go forward and kick goals. Will be his new team's primary midfielder and likely to get tagged most weeks, something he rarely dealt with at the Magpies.

Rohan Bewick: Started his career as a half-forward, but mixed his time between the wing and the occasional run-with role in the back half of 2014. Again will look to utilise his exceptional running power on a wing this season and build on the final 12 games of last year when he averaged 20 touches.

Billy Evans: The 187cm Evans was taken as a rookie after playing for Victoria Country last year. Is capable of kicking goals, but prides himself on winning the inside ball and will develop his game in the NEAFL this season.

Cian Hanley: Younger brother of Pearce, the 19-year-old will sit out the season after rupturing his ACL while captaining County Mayo in an All Ireland semi-final last August. When fit Hanley, an international rookie, is elusive and has good endurance. He has been undertaking his rehabilitation in Brisbane since November.

Pearce Hanley: The brilliant Irishman finished 2014 in stunning form, averaging 30 disposals over the final nine rounds. He will be sidelined until midway through this year, though, after requiring pre-season surgery on a hip. Hanley is agile, creative, quick, skillful, and arguably the Lions' most damaging player.

Matthew Leuenberger: The towering ruckman has had a strong pre-season after a meniscus injury restricted him to five games last year. At his best Leuenberger is one of the premier rucks in the AFL, with his first-class tap-work and athleticism around the ground. If he can remain healthy and forge a strong partnership with Stefan Martin, it will go a long way towards a successful season for the Lions.

Stefan Martin: One of the good news stories of 2014, Martin rejuvenated his career after he looked on the scrapheap midway through the year. He overcame three hamstring injuries in six months to play the final 12 rounds, average 22 disposals and become arguably the form ruckman of the competition. Competes well in the air, but once the ball hits the ground Martin is almost like another onballer. 

Sam Mayes: Struggled a bit in his second season as Justin Leppitsch threw him all over the ground to continue his education. Mayes is a clever footballer with an exquisite kick and plays his best as an outside midfielder who can run to half-forward and kick goals.

Zac O'Brien: The hard-running O'Brien was rewarded for his strong NEAFL form with five senior games last year. Small in stature but big on work-rate, the 24-year-old had his moments too, kicking a late go-ahead goal in a win over Carlton and racking up 30 disposals against Geelong. Likely to spend most of his year in the reserves, but can do a more-than-handy job if called up.

Jack Redden: After 112 successive games to start his career Redden was sidelined for the final eight games in 2014 after ankle surgery. Has not missed a beat in the pre-season though and again looms as a central cog to the midfield with his relentless attack around the ball. Redden is always in the top-five tacklers in the AFL and averages 21 disposals a game over his career.

Nick Robertson: The young West Australian got some chances in his debut season and showed there is plenty to work with. Got caught out by the speed of the game on occasions and will go back to the NEAFL to work on that in 2015. Robertson is fearless and an aerobic beast, but needs to tidy up his skills to become a regular in the top team.

Tom Rockliff: The new Lions captain, Rockliff had a memorable 2014, earning his first All-Australian selection and winning his second best and fairest award. Entering the prime of his career, the 25-year-old is a ball magnet who works relentlessly across four quarters. Finds holes in opposition defensive setups and is an ideal player to link defence and attack. Rockliff is the heart and soul of the Lions.

Archie Smith: A project ruckman entering his second season, Smith continues to improve at a rapid rate. He has added considerable bulk to his athletic 201cm frame and looks comfortable mixing it with senior bodies. The former basketballer is likely to spend the season in the NEAFL, which will do him no harm at all.

Trent West: Was doing a fine one-out job early last year in the absence of injured Leuenberger and Martin before being struck down by his own ruptured ACL. West is due back by round six and he will be an understudy to the leading duo.

Dayne Zorko: Hard to believe Zorko is entering only his fourth season such is the impact he has had. The 26-year-old is in the Lions leadership group and moved from primarily a half-forward role into the midfield. He is a terrier around the stoppages and has explosive pace to burst clear. Capable of going forward and kicking goals. - Michael Whiting

CARLTON

Tom Bell: Took some major strides in 2014, playing 13 matches including the Blues' final eight games. At 187cm and 98kg, Bell is one of the big-bodied midfielders who have come into vogue in recent seasons. Was one of the Blues' best players in their NAB Challenge loss to West Coast and could help shoulder more of Carlton's inside midfield load in 2015.

Blaine Boekhorst: The Blues' first pick in last year's national draft has impressed in his first pre-season at Ikon Park. The 21-year-old is a classy outside on-baller but has work to do on his fitness and strength. Played in the Blues' opening NAB Challenge game against the Eagles and should play senior football in 2015.

Andrew Carrazzo: Has endured a tough run with injury in recent seasons, but looks set to put that behind him after completing his first pre-season in five years. At 31 he remains a vital player for the Blues with his ability to shut down opposition stars and is set to return for his first game of 2015 against Collingwood in Bendigo on Sunday.

Patrick Cripps: One of the Blues' brightest young prospects, Cripps has enjoyed a strong pre-season save for a minor ankle injury he suffered at the club's January training camp at Mt Buller. The Blues' first pick in the 2013 national draft was hit hard by injury last year, but is well placed to play plenty of senior football this year. At 190cm he is a powerful midfielder who excels at stoppages.

Ed Curnow: One of Carlton's best performers in the NAB Challenge loss to West Coast, the run-with midfielder is an elite runner and hard at the ball. Although his skills can sometimes let him down, the 25-year-old is a consistent performer who is likely to be a regular part of the Blues' midfield rotations in 2015.

Matthew Dick: The former Sydney Swan reads the play well, has good endurance and has particularly impressed Carlton's coaching staff this pre-season with his hunger to improve. The 20-year-old is well built and can play in the midfield or across half-back.

Andrejs Everitt: Fully recovered from the knee injury that prematurely ended his impressive debut season at Ikon Park, Everitt is likely to be assigned the run-with roles he excelled in last season. Highly rated by the Blues for his leadership qualities.

Bryce Gibbs: After his career-best 2014 season Gibbs will share the Blues' vice-captaincy with Michael Jamison this year. Unlucky not to make last year's All-Australian team, the South Australian appears ready to join the game's elite players in 2015. A hard-nosed ball-winner at stoppages and lethal with his foot skills in open space, he is the complete midfielder.

Billy Gowers: The first-year rookie is athletic and skilled on both sides of his body. The son of former Hawk and Brisbane Lion Andrew Gowers, at this early stage of his career he is an outside player best suited to a wing or half-back. His first season is likely to be a development year in the VFL.

Nick Graham: The third-year midfielder has enjoyed an uninterrupted preparation for 2015 after being troubled by leg problems in previous pre-seasons. Has improved his running this summer, particularly his efforts at intensity, and is one of the candidates to fill the hole left by Brock McLean's departure.

Nick Holman: Made his debut in the Blues' big loss to Port Adelaide in round 22 last year and will be eyeing more senior opportunities in 2015. The 19-year-old is a role player with a strong competitive streak and can play as a run-with midfielder or at half-back. Had minor knee surgery this pre-season but has returned to the training track.

Chris Judd: Was close to hanging his boots up at the end of last season, but decided to play on after rediscovering his love of football. The two-time Brownlow medallist remains one of the competition's best contested ball-winners, but is likely to spend time in attack this season. Finished last season strongly and will enter 2015 in far better physical shape. Named to play his first game this year in the Blues' clash with Collingwood on Sunday.

Marc Murphy: Had enjoyed an excellent pre-season until he suffered a minor calf strain in the Blues' intra-club game late last month. The Blues hope their skipper will be available for their final NAB Challenge game against Geelong next weekend, but insist he is no doubt for their round one blockbuster against Richmond. One of the game's most courageous inside ball-winners.

Fraser Russell: The category-B rookie has returned to football after a four-year absence when he pursued an elite athletics career as a 200m and 400m runner. The 22-year-old was a strong junior player and his speed will be a weapon, but he has to adjust to the lateral movement required in football. Will spend this season developing in the VFL.

Kade Simpson: The 30-year-old remains one of the Blues' most consistent performers and is likely to divide his time between the midfield and defence this season, depending on where he is needed most. Suffered a minor ankle injury in late January but played in the NAB Challenge loss to West Coast.

Dale Thomas: The former Magpie is primed for a big season after completing his first full pre-season in recent years. Finally free of the ankle pain that had dogged him since 2012, the Blues are confident Thomas can return to the 2010-11 form that made him one of the best players in the competition.

Brad Walsh: The rookie is hardened for a first-year player after playing senior WAFL football with Peel Thunder last year. He has adjusted well to AFL training and has impressed the Blues with his professionalism. An inside midfielder who captained Western Australia at last year's NAB AFL Under-18 Championships.

Robert Warnock: Has completed his best pre-season in recent years and is well poised to reclaim the Blues' No.1 ruck mantle after being dropped late last season. Impressed in Carlton's intra-club game last month and the club is confident the 28-year-old has his best football in front of him. Named to play his first NAB Challenge game against Collingwood in Bendigo on Sunday.

Mark Whiley: The former Giant made a solid start to his first pre-season at Ikon Park before being sidelined with an Achilles tendon injury. The 22-year-old is still two weeks away from returning, but the 188cm on-baller should enjoy senior opportunities this year.

Cameron Wood: The former Brisbane Lion and Magpie finished last season in fine style, coming off the rookie list to lead Carlton's ruck division over the final six rounds of the year. Wood will start this season on the rookie list again, but played as the Blues' sole ruckman in the NAB Challenge loss to West Coast. - Nick Bowen

COLLINGWOOD

Taylor Adams: Collingwood sees Adams as the man most likely to step up and assume more midfield responsibility following the departures of Luke Ball and Dayne Beams. The 21-year-old is expected to go to the next level this season.

Mason Cox: Recruited from Oklahoma State University, the former college basketballer joins Fremantle's Aaron Sandilands as the tallest player in the League (211cm). Cox is likely to hone his craft in the VFL this season, but has already impressed the Pies with his improvement.

Jack Crisp: Recruited from the Brisbane Lions, as part of the Dayne Beams trade, Crisp is expected to add more depth to the Magpies' midfield. Renowned for his toughness inside the contest.

Jordan De Goey: Firming for a round one debut after an impressive first pre-season at the club. Relishes the contest and refuses to take a backward step against more experienced opponents.

Sam Dwyer: Knee and groin injuries played havoc with the midfielder's 2014 campaign, limiting him to 13 games. The 28-year-old hopes he can re-establish himself in Collingwood's best 22 and recapture the form he showed in 2013.

Nathan Freeman: Freeman was one of the strongest performers on the training track throughout the pre-season, keen to make up for some lost time. The speedy youngster had his 2014 season ruined by a serious hamstring injury.

Matthew Goodyear: The Calder Cannons product is renowned for his athleticism and decision-making under pressure. Has impressed the Magpies with his desire to do the hard work this pre-season.

Levi Greenwood: Signed with Collingwood after seeking more midfield time, despite finishing third in North Melbourne's best and fairest count last season. Has shaken off a foot problem and the Pies hope he can be a solid contributor through the engine room this season.

Brodie Grundy: A down year of sorts for the young big man in 2014, but Collingwood sees it as part of his development. The Magpies view Grundy as their ruckman of the future and he will be given every opportunity to turn himself into a genuine front-liner.

Brent Macaffer: Macaffer is well on track in his recovery from a second knee reconstruction and the Pies hope he may return at the midway point of this season. The midfielder turned himself into one of the best run-with players in the League in 2014.

Scott Pendlebury: The skipper is set to take on even more responsibility this season, following the departures of premiership players Dayne Beams, Luke Ball, Nick Maxwell and Heritier Lumumba. Remains one of the best players in the AFL.

Steele Sidebottom: Sidebottom is coming off a career-best year, in which he averaged 26.7 disposals a game. More midfield time meant a lift in the star utility's consistency and the Magpies hope he can go to another level to cover the loss of Beams this season.

Dane Swan: With a self-described "putrid" season behind him, the Magpies are confident Swan can return to his All-Australian levels from past years. The ball magnet was slowed by off-season hip surgery, but has fought back and is raring to go in 2015.

Josh Thomas: Likely to assume an expanded role through the midfield this season following Beams' departure. Has had to fight back from a skin infection in his hand as a result of fending off a would-be mugger while on holiday in Los Angeles in the off-season.

Jarrod Witts: Set to play his first game of the season in the VFL on Saturday after recovering from off-season shoulder surgery. Witts' ruck partnership with Grundy shapes as crucial to the Magpies' finals hopes.

Clinton Young: Young's raking left boot and ability to carry the lines are an important part of Collingwood's game style. Has had an interrupted preparation this pre-season and is still up to two weeks away with a hamstring complaint. - Ben Guthrie

Big things are expected of ex-Giant Taylor Adams in 2015. Picture: AFL Media

ESSENDON

Kurt Aylett: The former Giant was delisted by the Dons at the end of last season but then re-drafted as a rookie. He played two games for the Bombers last year and can be used in a range of spots, mainly through half-back or a midfield role where his hard running comes to the fore.

Tom Bellchambers: Bellchambers' horror 2014 season is behind him and he is ready to shoulder the ruck load this year after the departure of Patrick Ryder. A pre-season ankle reconstruction ruined the big man's campaign last year and although he returned for eight games, he never reached his peak. At his best he is a smart tap ruckman and dangerous tall forward option.

Alex Browne: The Bombers' medical team treated Browne's knee reconstruction conservatively, particularly in the latter stages. It meant he took a little longer than hoped to get back into full training, but now there, the midfielder is going well. His injury struck at a bad time – he appeared likely to fit into the first-choice Essendon line-up last year – but will be aiming to make up for lost time in 2015.

Adam Cooney: The former Western Bulldog has had a healthy pre-season, even showing some of his trademark dash at training sessions. Brought to the club to provide some experience, speed and goalkicking prowess through the midfield, Cooney should add spark to the Bombers' line-up.

Jonathan Giles: With three goals against St Kilda last weekend, Giles showed why the Bombers were keen to sign him during last year's trade period. The former GWS ruckman was squeezed out of the Giants' regular side last year but should get plenty of opportunities this year at Essendon with Ryder gone.

Brendon Goddard: Goddard is due to play his 250th game in round three and enters a 13th AFL season in excellent shape after trimming down slightly and noticing the difference. Likely to swing between the midfield and half-forward again, where he has been able to contribute 35 goals in his two seasons with the Bombers. His recruitment as a free agent at the end of 2012 couldn't have been better for the club.

Will Hams: Injured an ankle during a training session in February but the Bombers were relieved that it was not as bad as first thought. Hams' tenacity and hard-at-it attitude has many admirers at the club, and they will be hoping he can have more luck with his body after hip problems curtailed his 2014 season. 

Dyson Heppell: There was a scare at Bomberland when Heppell went down with a knee injury two weeks ago, but it was only minor and the star midfielder should be soon back training after surgery. They cannot afford to be without him for long, given Heppell's importance to the Bombers' midfield. He signed a five-year contract recently tying him to the club until the end of 2020, and he looms as the club's next captain.

Heath Hocking: The club had hoped Hocking's groin surgery in December would only sideline him until the end of January, but it has not recovered to that timeline and he's in doubt for the start of the season. He played with the groin problem last season, when he spent another year as the club's go-to stopper.

Ben Howlett: Gives the Bombers some tackling presence and a hard edge around the stoppages. Showed some flair last year when he surprised by booting five goals against Richmond, but is generally a no-fuss player who gives his all.

Elliott Kavanagh: A big year looms for Kavanagh, who put himself on the trade table last year but ended up staying at the Bombers. He has had a good summer but needs to put consistent performances together to earn his senior spot and then hold it. He is composed when in possession and has good foot skills, and Essendon will be hoping the top-20 pick can find his niche.

Jake Melksham: After a really strong season in 2013, being used as a run-with midfielder, Melksham didn't manage to find the same level of consistency last year. With confidence, Melksham is a damaging and dangerous player for the club. He can use the ball, kick goals, and isn't afraid of going hard at the ball. 

Zach Merrett: Essendon's first pick at the 2013 NAB AFL Draft, Merrett burst onto the scene last year as a creative and crafty half-forward. He'll still play there a bit this year, but after spending summer with the midfield group, Essendon can expect to get more out of the smart left-footer around the ground. Has great work ethic and an appetite for learning, making him an exciting player of the future.

David Myers: A series of niggling injuries over the pre-season has been annoying for Myers and the Bombers, but shouldn't impact the start of his season too much. The 25-year-old is an important player for the club, with his booming left-foot and power at the contest making him a unique midfield option for coach James Hird. Few at Essendon get the distance with their kicking like Myers so they need him in full flight.

Brent Stanton: A veteran of Essendon's midfield, Stanton continues to be a strong pre-season performer. The 28-year-old remains near the front of the group in time trials, and is a hard trainer. He played every game last year and enjoyed another solid season.

Jobe Watson: After missing 10 weeks with his hip injury last season, the Brownlow medallist will be hoping for an uninterrupted run in 2015. He will captain the club for the sixth straight season and is a highly respected leader. The Bombers have built their midfield around Watson in recent seasons, and although less reliance falls his way, he remains the club's best and most important player.

David Zaharakis: Zaharakis sent a shiver down the spine of Essendon officials when he hurt his knee at a training session weeks ago, but the medial ligament damage was minimal and he's on track for being fit for round one. After a relatively quiet start to last season, the speedy and skillful midfielder had a purple patch in the middle of the year and showed his class. A vital member of Essendon's on-ball brigade due to his goalkicking nous. - Callum Twomey

Captain Jobe Watson still remains Essendon's most important player. Picture: AFL Media

FREMANTLE

Jacob Ballard: Powerfully built midfielder who spent last year racking up possessions in the WAFL for Peel. Has the frame to walk into AFL football but remains on the rookie list for now. Has had some lower leg issues this pre-season and is still doing conditioning work away from the main group.

Michael Barlow: Consistent reliable midfielder and key component of the Dockers side. Was having a good pre-season until he hurt his right ankle in the first NAB Challenge game against Melbourne. The severity is unknown but he missed training on Wednesday.

Connor Blakely: Impressive youngster who has been likened to David Mundy in size and languid movements. Has shown incredible development during the pre-season and has mature body. Played only half a quarter in the first NAB Challenge game but he dominated a WAFL practice match last weekend.

Zac Clarke: The ruckman started the pre-season with a knee issue but has worked his way through it and looks in fine shape. Has had a much better preparation this year than last season and there is a hope he can return to the form and athleticism he displayed in 2013. 

Ryan Crowley: The veteran tagger has had an interrupted pre-season and continues to be managed. He did not play in the club's first NAB Challenge match and has not been named for the second. He ran laps at Wednesday's main session. Should be available for the start of the season but it is not guaranteed.

Matt de Boer: Endured a frustrating 2014 with a knee injury and poor form causing him to drift to the outer after being a fixture in the side. Signed a one-year deal and has put in an enormous pre-season to try to regain his place as a run-with midfielder who can also play a defensive forward role.

Nat Fyfe: The AFLPA MVP and two-time best and fairest winner has added a couple of kilograms to his legs to become more explosive in midfield stoppage situations. Continues to work on his goalkicking and is determined to improve again. Suffered a slight hamstring strain and missed the first NAB Challenge match but is raring to go now.

Brady Grey: Young Tasmanian who has come late to football after playing elite soccer throughout his youth. Tenacious runner who impressed in the WAFL last year and was an emergency on three occasions before stress fractures in his back flared late in the season. Likely to get a chance this season but needs to work on his disposal.

Jonathon Griffin: Fought his way back from a knee reconstruction in 2013 but played just one AFL match and played the rest of the year in the WAFL. Has had a good pre-season and is putting pressure on Zac Clarke for the second ruck role.

Jack Hannath: Continuing his development behind Sandilands, Clarke and Griffin. Has been working on his forward play and running patterns during the pre-season. Will be a back-up option while the senior players are fit but is likely to play at some stage throughout the year.

Ed Langdon: Younger brother of Tom who is at Collingwood. Has been managed during his first pre-season at AFL level after hardly playing last year before he was drafted because of injury. Will spend the early part of the year developing in the WAFL.

Craig Moller: In his third year on the rookie list, the young ruckman played one game in 2013 but played more WAFL reserves games than WAFL league games last year. Will remain at Peel barring a spate of injuries to the ruck stocks.

Anthony Morabito: Was the feel-good story of 2014 when he returned to play three matches after three years on the sidelines. Had a huge knee scare in September and has not been able to get any continuity during the pre-season because of ongoing soreness. Has been trying to up his running loads recently. It is unknown when he will return to main training group.

David Mundy: Classy midfielder who is among the competition's elite players. May begin to spend more time across half-back this year where he started his career to ease his workload. Remains an important clearance player and will be at the coalface in big games.

Tendai Mzungu: Signed a contract extension during the summer. He is the club's best runner, consistently winning the 3km time-trial. Versatile utility who also spends a bit of time at half-back and can drift forward and kick a goal when needed. Important member of the side. 

Lachie Neale: Took his game to another level in 2014, becoming a consistent ball-winner in the midfielder. Adds another element with his elusiveness and smarts around the contest and is used a lot as a linkman in transition. Has become a fixture in the Dockers' midfield rotation.

Clancee Pearce: Did not play much last year after a limited pre-season because of Achilles surgery. He has had a fantastic summer and was busy in the Dockers' first NAB Challenge clash against Melbourne. Can play a variety of roles through the midfield or in defence. Will be pushing for a permanent place in the first-choice 22. 

Danyle Pearce: Has had a limited pre-season because of a couple of leg issues. Hasn't clocked up many kilometres but he has started run freely in the past couple of weeks. Still hasn't played yet and wasn't named to face the Sydney Swans. Will be touch and go for the last NAB Challenge clash, but should be OK for the season proper.

Aaron Sandilands: Has been managed through the pre-season but looks fit, strong and set for another good year following a fourth All-Australian selection in 2014. The coach is spruiking that he could play beyond this year and possibly next.

Tommy Sheridan: Fremantle's first-round draft pick in 2011 and is out of contract this year. Played just eight matches last year and none after round 13. Has had a strong pre-season to date. Gathered 11 touches in the first NAB Challenge game and gets his chance to press his case further this week.

Nick Suban: Started brightly in the first NAB Challenge match last week and the coach was impressed with his work. Hard-running midfielder with pace and an ability to kick goals. Hoping to go to the next level this season.

Colin Sylvia: Has not returned to Fremantle training since he was sent to Peel Thunder for failing to meet minimum standards. Only in the second season of a three-year deal. Will need a dramatic improvement in attitude and performance at training and in games with Peel before being welcomed back to Fremantle.

Lachie Weller: Talented youngster who has impressed during his first pre-season. Was a dominant force in Peel's first practice match last weekend and has been named in the Dockers' 29-man squad to face the Swans. Has worked closely with the senior midfield group all summer and could play senior football this year.  - Alex Malcolm

Can Nat Fyfe get even better in 2015? Picture: AFL Media

GEELONG

Jimmy Bartel: After stints at half-forward and half-back in recent seasons, Bartel is set to return to the midfield to add some hardness around the contest. The 2007 Brownlow medallist still reads the game better than most and his marking is a clear strength.

Josh Caddy: Set to use an impressive finals campaign as a springboard into this season. Now in his third year at Geelong, Caddy will be given every opportunity to cement himself as a consistent AFL midfielder. Aggressive at the contest and steps up in big moments.

Nakia Cockatoo: There is a fair buzz about Cockatoo down at the Cattery and for good reason. The club's first-round draft choice (No.10 overall) has electric speed and a great sidestep. A genuine chance to make his debut in round one against Hawthorn.

Jordan Cunico: The young draftee possesses excellent endurance and is a powerful kick. Has been training in defence and is likely to play off half-back in the early part of his career.

Mitch Duncan: Duncan is a running machine and importantly works both ways. He is a devastating finisher in front of goal and his link-up work through the middle of the ground is first-rate. An integral member of Geelong's side and a potential future captain.

Dean Gore: Along with Cockatoo, Gore was the most impressive draftee on the training track during the pre-season. He is solid over the football and has the body built to play early in his career. Look for him to play some senior games as early as this season.

Cameron Guthrie: Set to enter the next phase in his development, with Geelong intent on freeing him up to win more of the footy this season. Spent last year as a run-with midfielder after a couple of years learning his craft in defence. Regarded as a future club leader.

Brad Hartman: Has been given indefinite leave from the club to work through some personal issues. Hartman has played five games in his two seasons at Geelong.

George Horlin-Smith: Horlin-Smith was limited by a nagging quad complaint through the pre-season, but is fit again and ready to build on an impressive 2014. The 22-year-old thrives inside the contest, but he is also clever around goals.

Jarrad Jansen: At 19 Jansen is as solid as they come and has the frame to mix it with some of the game's bigger midfielders. Jansen's strength in the contest is often telling and 2015 could be his year to break into the senior team.

Steve Johnson: The star Cat continues to dazzle, and frustrate (at the same time), football watchers with his unique style. Johnson's match-winning ability is unquestioned and at 31 is still racking up plenty of the footy. A key to Geelong's finals hopes.

James Kelly: Spent last season as a small defender, but is preparing to move back into the midfield this season to improve the club's contested ball-winning ability. Kelly has shown his toughness and uncompromising nature throughout his career.

Padraig Lucey: The Irishman got a small taste of what playing in the AFL was like when he was part of the Cats' NAB Challenge team that took on Gold Coast in Townsville. Lucey is still developing, but the Cats see plenty of upside in the 203cm ruckman.

Hamish McIntosh: Missed last year's semi-final against North Melbourne with a knee complaint and has battled through the pre-season after surgery. Slowly working his way back, with the Cats to face a tough test in determining their preferred ruck set-up.

Tom Read: The former South Australian has been training with the ruck group, where the Cats see his mix of athleticism and aggressiveness fitting best. Has already established himself as a popular teammate at the Cattery.

Joel Selwood: A proven match-winner, a star ball-winner and one of the best captains in the AFL. Selwood does not have much more to add to his resume, although there is no doubt he will do his best. As competitive as they come and one of the best players in the League.

Dawson Simpson: Simpson has taken some small steps in his recovery from back surgery late last season, managing to turn out in the Cats' two NAB Challenge games. Simpson's height offers something for Geelong, but the club is likely to take a horses-for-courses approach to its big-man stocks this season.

Mathew Stokes: Stokes had a tremendous start to last season until an ankle injury slowed him up midway through the season. The 30-year-old has a habit of finding unmanned space out on the ground and continues to find the ball with ease. – Ben Guthrie

GOLD COAST

Gary Ablett: He's now 30, but there is little doubt Ablett is still the best player in the game. The dual Brownlow medallist has taken a cautious approach to his rehab from the dislocated shoulder that ruled him out of the final seven weeks last season, but he will be right come round one. Has used his recovery time to be in the best shape of his career, clocking personal bests over 2km at training. 

Harley Bennell: A minor pre-season calf injury has not slowed Bennell down. The silky-skilled West Australian missed a few weeks of training, but is back in full flight. Previously seen as an outside ball specialist with sublime finishing skills, Bennell stepped up big time in Ablett's absence last year and showed he could mix it with anyone around the contested ball.

Daniel Gorringe: Big year for the athletic ruckman who has failed to cement a regular spot in his four seasons. Gorringe asked for a trade in the off-season but has ended up back at the Suns, where new coach Rodney Eade has trialled him on a wing and in defence during the pre-season.

Mitch Hallahan: Stuck behind a plethora of superstars at Hawthorn, Hallahan has headed north after just six games in four seasons. He is a strong-bodied inside midfielder, and although not blessed with great speed, knows how to find the ball. Hallahan is expected to do a lot of the inside grunt work to ease the burden on Ablett, Swallow, Prestia and O'Meara.

Jesse Lonergan: The energetic Tasmanian has struggled for a slice of luck in his first two seasons, suffering two broken hands and two torn hamstrings. He rolled an ankle in the pre-season, but has bounced back and is on the fringe of senior selection.

Jack Martin: An uninterrupted pre-season has the prodigiously talented West Australian in ideal shape for his second year. He is stronger and fitter, which is a scary thought for opposition players and coaches. Martin is still lightly framed but is strong over the ball, spring-heeled and has exquisite skills on both sides of his body. Watch for him to mix time between half-forward and the midfield.

Tom Nicholls: A PCL injury interrupted a promising 2014 for Nicholls and now he is in a dogfight with Zac Smith for the No.1 ruck role. Extremely talented around stoppages, Nicholls is also good once the ball hits the ground.

Jaeger O'Meara: O'Meara had surgery to both knees late last year, disrupting his pre-season. However, the 21-year-old is as diligent as any player on the Suns list. Is expected to play the final pre-season match and be available for round one.

Dion Prestia: After an outstanding past two seasons, Prestia can be relied upon for the same output most weeks. Like many of his teammates, had a slightly interrupted pre-season with back and hamstring niggles, but will be right to go against Melbourne in the first game. Mixes pace and outside dash with a hunger for the inside ball.

Andrew Raines: Given a lifeline after being delisted by the Lions, the professional Raines has been recruited as a mature rookie to help add depth to the inexperienced midfield. A PCL injury has derailed his pre-season, and while Raines is primarily expected to add guidance at NEAFL level, he can also step in and do a job for the seniors should he be required.

Michael Rischitelli: Finally over his injuries, Rischitelli revived his flagging career in 2014. He played 21 games, averaged 19 disposals and was a beacon of consistency. Still a valuable contributor with his ability to absorb punishment around the contest, win the contested ball and use it well off both sides of his body.

Luke Russell: Seemingly fell out of favour last season, but Russell has overcome a hip injury and will be in consideration for the starting 22 again. Might have slipped down a few notches in the pecking order, but has good speed and a thumping kick. At his best is another quality outside runner for the Suns mix.

Alex Sexton: Had an excellent pre-season and thrown his name right into the mix. Looks composed in traffic and has good speed and agility, so don't be surprised to see Sexton get some chances early in the year.

Matt Shaw: Another who had a patchy 2014, Shaw struggled to string good games together. He is on the fringe of senior selection, but runs hard both ways and is best used on the wing where he can utilise his excellent endurance.

Zac Smith: If his first NAB Challenge outing against Geelong is any indication Smith looks a new man. Dogged by injury over recent seasons, the athletic ruckman appears to have found the long sought-after aggression the coaching staff and supporters have been waiting to see. If Smith can produce that physicality on a weekly basis, it will help his push to be the No.1 ruckman and his team's push to the finals.

David Swallow: The former No.1 draft pick won his first best and fairest last year after a magnificent season. Swallow has always been a courageous inside player, but in 2014 began to get more on the outside, where he could use his blistering acceleration and improving skills. An uninterrupted pre-season leaves him in good shape for a repeat performance this year. - Michael Whiting

GREATER WESTERN SYDNEY

Jake Barrett: An outstanding runner who is eyeing off a senior debut after an uninterrupted pre-season. Impressed at NEAFL level last year, averaging 25 disposals. Is developing as a defensive midfielder.

Tomas Bugg: Boasts outstanding endurance, enabling him to be deployed in negating roles as well as other roles in defence. Finished third and fourth in GWS' pre-season time trials and will be looking to step up after his fourth pre-season.

Stephen Coniglio: Has had an extended pre-season after a broken thumb sidelined him for the final six rounds. Injury has dogged his career to date, but the out-of-contract West Australian's ability is obvious. Tagged Ryan Griffen with impressive results during an intra-club.

Tim Golds: The athletic 191cm midfielder wore the green substitute's vest in his three games and played mostly on a wing last season. Showed encouraging signs in the NEAFL and will be pushing for more game time this year after re-signing in December.

Toby Greene: Ball magnet who bounced back from off-field issues in phenomenal style late last year. The workhorse re-committed to the Giants until 2018 and looms as a key player in GWS' emerging on-ball division.

Ryan Griffen: Dispelled summer rumours of more back issues with a scintillating display in the NAB Challenge opener. Griffen has said he is refreshed after falling out of love with the game and his presence is sure to take the heat off his younger teammates.

Rory Lobb: Developing ruckman who played two matches last season and showed promise before a knee injury sidelined him for five weeks, which delayed his start to pre-season. Vying for second ruck spot, has filled out over summer and can take a mark up forward.

Shane Mumford: Winning the club champion award, the Kevin Sheedy Medal, in his first season showed the big ruckman's importance to the young Giants. Mumford's physical presence makes the midfielders around him walk taller. Crucial to Leon Cameron's plans and is feeling the best he has in five years.

Andrew Phillips: Has endured a frustrating two seasons with injury but has impressed over pre-season. Led the ruck in the Giants' NAB Challenge opener and is looking to return to his 2012 form.

Tom Scully: Came back post-Christmas and blitzed the time trial, but has been hampered by an ankle injury since February. The running machine is listed as two weeks away from returning. Should benefit with some pressure lifted from his shoulders after Ryan Griffen's arrival.

Dylan Shiel: Blessed with an exciting mix of speed and endurance, Shiel has taken his running ability to another level over summer. Looms as a key figure in a dangerous midfield.

Jacob Townsend: Is on crutches with bone bruising in his foot, which he suffered in the opening NAB Challenge match. The defensive midfielder's slight setback will sideline him for about a month.

Adam Treloar: A standout over pre-season, the rising star has continued his brilliant form from 2014. Has been tearing up the track alongside Dylan Shiel and Devon Smith.

Callan Ward: Led the young Giants superbly last season and was named in the All-Australian 40-man squad for the first time. His load should be lightened considerably with his old Western Bulldogs teammate Ryan Griffen taking more of the opposition's attention. Could go to another level.

Lachie Whitfield: Smooth-moving on-baller who had a delayed start to pre-season after foot and shoulder surgery. Is fighting fit and looking forward to a big year. Highly rated within the club.

Sam Schulz: Battled minor niggling injuries over summer. The rookie had a broken rib towards the end of last season and is yet to have a clear run at establishing himself. – Travis King
