WITH DALE Thomas set to come up against the Magpies for the first time on Friday night, we take a look at those who have ignored the fabled Collingwood-Carlton rivalry, and joined the hated enemy.

RAY BYRNE
Carlton 1973-78 (81 games, 13 goals); Collingwood 1978-83 (121 games, 10 goals)
Consideredone of the most unfortunate footballers in VFL/AFL history, Ray Byrneplayed in four losing Grand Finals – including two against his formerclub. The courageous defender played in Carlton's 1973 team that lost toRichmond, and Collingwood's side that went down in three-straight GrandFinals between 1979-81. Rubbing salt into the wounds, it was the Bluesthat defeated the Pies by five points in '79 and 20 points in '81.Recruited from Carlton's Bendigo zone, Byrne transferred to VictoriaPark during the 1978 season, coming up against his old club at PrincesPark in a 41-point loss later that year. As a Magpie, he had a 6-8win-loss record against Carlton.

CAMERON CLOKE
Collingwood 2004-2006 (21 matches, 11 goals); Carlton 2007-2009 (36 matches, 25 goals)
TheCloke name is famous at Collingwood, made so by David Cloke. SonCameron spent two years on the Magpies' list between 2004 and 2006. Hewas delisted, along wih older brother Jason, at the end of 2006, but wasthrown a lifeline by the Denis Pagan-led Carlton. Injuries hampered hisprogress at the Blues and he struggled to establish himself inCarlton's side. Cloke was part of an infamous intra-club playingincident that involved Setanta O'hAilpin being suspended from the clubfor a month, after he punched and kicked his teammate in an off-the-ballconfrontation.

JIM CROWE
Carlton 1929-34 (83 games, 37 goals); Collingwood 1936-37 (21 games)
A Carlton-born ruck-rover at the start of his League career, Jim Crowe ended his playing days as a premiership defender for bitter rival Collingwood. Crowe played finals in each of his first five seasons with the Blues, including the losing Grand Final against Richmond in 1932, but fell out with the club over his role in the team midway through 1934. Two years later, the then 27-year-old returned to the competition with Collingwood. Crowe's only clash against his former side resulted in a one-point defeat in round 17, but he had the last laugh by playing in the Magpies' 11-point Grand Final triumph over South Melbourne three games later.
 
MICK McGUANE
Collingwood 1987-96 (152 games, 128 goals); Carlton 1997 (3 games, 1 goal)
A premiership midfielder, two-time Copeland Trophy winner and All-Australian at Collingwood, McGuane is best remembered by most football fans for his weaving, seven-bounce Goal of the Year run from the centre square against Carlton in 1994. The boy from Sebastopol was close to the peak of his powers then, but three seasons later lined up for a forgettable stint at Carlton. Playing in just his third game for the Blues – the infamous M&Ms match against Adelaide at Princes Park – McGuane's groin gave way, ending his season and, ultimately, forcing him to hang up the boots as a 29-year-old. He never played against his beloved Magpies.

PETER McKENNA
Collingwood 1965 - 1975 (180 matches, 838 goals); Carlton 1977 (11 matches, 36 goals)

An all-time Collingwood great, McKenna led the Magpies' goalkicking in eight consecutive seasons between 1967 and 1974. He won the club's fabled Copeland Trophy in 1970; the VFL's Coleman Medal in 1972 and 1973 and was recognised as an All Australian in 1972. McKenna left Collingwood in 1975 and after a year playing for the Devonport Magpies in Tasmania's North West Football Union, sought a return to the VFL 1977. The Magpies were not prepared to fork out big money for their former star, so he reluctantly played with Carlton. By that stage, it was clear he was past his best. McKenna was inducted into the Australian Football Hall of Fame in 1999.

RUSSELL OHLSEN
Carlton 1975-78 (47 games, 25 goals); Collingwood 1979-81 (50 games, 22 goals)

Adispute with Carlton saw the extensively tattooed utility move toCollingwood for the 1979 season. Originally from Maryborough, theruck-rover type who was also used to tag opposition players played inthe Magpies' losing Grand Final sides in 1979 – where he had his jawbroken at the hands of former teammate Trevor Keogh – and again in 1980.

HAROLD RUMNEY
Carlton 1925-26 (15 games, nine goals); Collingwood 1927-35 (171 games, 28 goals)
Despite attending Collingwood Technical School, Rumney played in the VFA with Brighton and was residentially tied to Carlton. The half-forward didn't impress at the Blues and was cleared to Collingwood for the 1927 season, where he starred on the half-back flank and in the back pocket. He won Collingwood's best and fairest in 1931 and played in the premiership sides of 1927-1930 and 1936. He died in 1987.

HEATH SCOTLAND
Collingwood 1999-2003 (53 games, 12 goals); Carlton 2004 - 2013 (214 games, 69 goals)
Scotlandplayed in Collingwood's 2003 losing Grand Final, but sought greateropportunities and was traded to Carlton before the 2004 season. He hashas become an integral member for the Blues, winning the club's best andfairest award in 2012. At his best, his rebound and polished footskills were a superb addition for Carlton. He featured in the club'sleadership group between 2007 and 2010 and helped the Blues transition anumber of the club's young players. His kicking, on both sides of hisbody is a feature, and he has been cool and composed under pressurethroughout his career.

HARRY SULLIVAN
Carlton 1950 - 1954 (31 games, 16 goals); Collingwood 1955-1960 (78 games, five goals)
Sullivanstarted his career at Carlton, but jumped ship to the Magpies in 1955after his opportunities became limited. Initially a key forward at theBlues, Collingwood reinvented him as a full-back ahead of the 1956season with spectacular results. Sullivan anchored the Magpies' defencein the club's 1956 Grand Final loss to Melbourne, but then was part ofthe team that famously denied the Demons four straight premierships in1958. He was renowned for the timing of his defensive spoils and notbeing shaken when under pressure.

DALE THOMAS
Collingwood 2006-13 (157 games, 121 goals); Carlton 2014-current (six games, two goals)

After being selected by the Magpies with the second overall pick in the 2005 NAB AFL Draft, Thomas did as many expected he would and followed former Collingwood coach and mentor Mick Malthouse to Carlton at the end of 2013. The 2010 premiership player battled an ankle injury in his final season as a Pie and he was forced to answer questions all year about his future after putting off his contract talks. At the season's end, he exercised his rights as a restricted free agent and the Pies declined to match the hefty offer the Blues put forward.
