The Bombers' struggles this year are mirrored in the statistics, with their start and finish to games particularly damaging. Their fourth-quarter results are the second worst in the competition and although some of that can be attributed to the youth in the squad, it is also a concern in terms of their fitness and ability to run out games. They have won seven out of 15 third terms, which makes that their best quarter, but even then they have battled to make the most of their dominance near goal. That has been a problem throughout the whole year, and over the past seven games the Bombers have averaged eight goals a game.

Essendon's scoring accuracy improves as quarters go on this year. In the first 10 minutes the Bombers score at 50 per cent, from the 10 to 20-minute marks they score at an accuracy of 57 per cent, and they score at an accuracy of 65 per cent in the time-on period. - Callum Twomey

The Dockers' first-quarter dominance was a feature of their play when they won the first nine games of the season, but it is as much to do with their defence as their attack. They kicked six goals in the first term last week against Carlton. It was only the second time they have kicked six goals or more this season and they have kicked five goals three times. But teams can't score against Fremantle in the opening term. In the first eight rounds they did not concede more than two goals in an opening term. Only Richmond (eight goals in round 10) and Hawthorn (four goals in round 15) have got hold of them.

Geelong is ranked second in the AFL for points scored versus points conceded in first quarters, getting the jump on their opponents 10 times in opening terms this season. The Cats might start full of running, but their problem has been maintaining it across the course of a game. After half-time is where the figures become alarming for Chris Scott's men. Geelong is placed 11th in third quarters won and 15th in winning final terms, with the club having won just four final terms for the year. If the Cats are to make the finals for the ninth straight year, their consistency throughout games will need to improve markedly.

Contrary to popular opinion, Gold Coast is actually running out their matches well. Although they've played with one of the youngest teams in the competition for much of the season, the Suns are ranked 11th in fourth-quarter point differential and has won the final term in seven of its 15 matches. They are often competitive in the opening quarter but are getting blown away in terms two and three, losing an average of 20 points a match in those periods. It could be a lack of concentration, a lack of discipline, or the opposition putting the foot down, but whatever the case, Gold Coast has to improve its football through the middle of matches to stay competitive.

Whatever coach Leon Cameron is saying at the half-time break is doing wonders for the Giants – the third term is clearly their best quarter going by the statistics in 2015. The best example was the carnage they unleashed on Melbourne in round two in Canberra. GWS booted nine goals for the term that day, their highest-scoring quarter ever, turning a 27-point half-time deficit into a 26-point advantage by three-quarter time. In saying that, maybe Cameron should use his half-time speech before the game, as the Giants are notoriously slow starters. They're ranked 14th in the League and interestingly enough, went goalless in the opener against the Demons that same day in round two.

The Giants put the Demons to the sword in their massive round two comeback. Picture: AFL Media

It's called 'the premiership quarter' for a reason, and there's little surprise that the raging flag favourites have dominated the third term this year (won 14, lost one). Hawthorn boots an average of 35 points in the third quarter, more than doubling their opponents' score (17 points). It's becoming nearly impossible to stop Alastair Clarkson's in-form and versatile outfit. In their past six games, the Hawks have piled on more than 100 points – including a combined 261 points in hammerings of flag challengers Fremantle and the Sydney Swans over the past fortnight. The theory that West Coast could be the main threat to the Hawks' three-peat is supported by the total quarters won by the powerhouse clubs. Hawthorn tops the list (47), followed by the Eagles (41), Fremantle (37) and the Swans (35).

The Demons' inability to stick with their opponents for a whole game has cost them once again this season but their fast starts show effort is not an issue. Three shocking third quarters against Greater Western Sydney in round two, Hawthorn in round seven and Essendon in round 15 distort the figures, and they have managed to put together nine quarters of five goals or more already this season, a marked improvement on 2014 when they managed to kick five goals or more in a quarter just six times. The Demons are a much more balanced outfit and their low ranking in final quarters is due to their youth, having played six first-year players and used 37 players this season. The trend remains encouraging but there is plenty of work ahead.

The Roos have regularly put themselves behind the eight-ball with slow starts in 2015. Only Richmond, Gold Coast and Carlton have won fewer first quarters than North's six, while only the Blues, Suns, Brisbane Lions and St Kilda have worse scoring differentials than North's -40 in opening terms. The Roos have been able to work their way back into matches in the middle terms, ranking seventh in differentials in both second and third quarters. However, they have dropped off again in final quarters, when they have been outscored by a differential of -25 (10th in the AFL). Tellingly, two of North's four goalless terms came in fourth quarters, in the 12-goal losses to Adelaide in round one and Fremantle in round eight.

The Power might need to take a serious look at what they do during half-time breaks, because the players rarely come out firing in the third quarter. They start games like a team possessed and are one of the League's best sides in opening terms. But that success tends to dry up quickly, with their opposition making ground until the Power fight back to a small degree in the final quarter. It reflects exactly what coach Ken Hinkley has previously stated – the consistency just isn't there this year. His players are continually beaten for the majority of quarters but rally late, often when the result is already decided.

The Power celebrate a win over Hawthorn in the year's most topsy-turvy game. Picture: AFL Media 

Richmond's starts haven't been identified as a big issue because the club has recovered and got itself into a position to finish top four. The Tigers' poor starts, however, nearly cost them that chance. Every loss they have had this year, they have ended the first quarter behind. It hasn't been by big margins, kicking 11.16 to their opponents' 16.14, but its enough to put them on the back foot. Conversely, the Tigers are ending matches impressively, winning 11 of 15 fourth quarters. The exception was in round 16 when St Kilda came from 52 points behind at three-quarter time to nearly cause a boil over, eventually losing by 16 points.

The Saints have staked their claim as a team that can never be written off, with coach Alan Richardson instilling a never-say-die attitude in his young players. The Western Bulldogs know this all too well. In round six the Saints kicked 12 goals to three after half time to win by seven points. Then in round 13 they got within a goal after trailing by 21 points in the fourth quarter. The final quarter is clearly the best quarter for St Kilda, with teams never truly comfortable against the rebuilding team, particularly at Etihad Stadium, where their running game excels.

The statistics show that the Swans might take a quarter to get going – their only two goalless quarters of the year have been the opener in round one against Essendon and the same term against Hawthorn last week – but when they do they're hard to stop. They're ranked first for scoring differential in the second term with West Coast – they kicked 6.3 against the Giants in round three, their best of the season, and have kicked 52.44 in second quarters, while keeping the opposition to 30.44. The third term is the only one in which the Swans have been outscored, but it's only been a small differential.

The Eagles' second halves have been exceptional. They have won 12 third quarters out of 15 and are the best final-quarter team in terms of scoring differential. Teams that are playing West Coast need to establish a healthy first-term lead or they will struggle. The Dockers held a 52-point quarter-time lead in the round three derby and only won by 30 points. North Melbourne had a three-goal lead at quarter-time in round 10 and won by 10 points. The exception was Adelaide. The Crows led by 14 points at quarter-time in round 15 but the Eagles kicked 8.7 to 0.1 in the second term to put the game away.

The Bulldogs have lost more quarters than they've won in 2015 (27 won, 32 lost), but their first quarters have really set the game up for them. Being the competition's fourth youngest side is probably a contributing factor to why they've struggled in final quarters, as young bodies tend to run out of steam. But in a quirk, the Dogs' barnstorming round 15 win over the Suns saw them kick the season's second biggest final quarter score.
