Pies fans would believe that once a Collingwood player leaves their club for another, they all of a sudden become a superstar and wonder why they couldn't play like that at our club.

Personnel changes in coaching staff and the general direction the club wanted to go in, meant that trading of players had to occur to ensure that success was in reach.

A list is compiled to highlight those who, if they stayed in the black & white, could've had an impact to this day or until they retired.

Here are the best 10 players Collingwood have traded or delisted since 2003:

4. Josh Fraser

Another Collingwood ruckman traded to the Suns looking for more opportunity.

Fraser burst onto the scene in 2000 where he played 21 games out of a possible 22 games in his debut season. From there, the mobile and agile ruckman who stood at 202cm, was consistently in the Pies' best 22 for the next few years.

He started to lose favour as the Pies recruited "third-tall" Leigh Brown and Darren Jolly around 2009 which saw Fraser starting to be squeezed out.

The Gold Coast Suns' first year saw Fraser as a start-up player who added to his 200 games that he tallied up at the Pies. His career wasn't long at the Suns as his experience on the field wasn't needed post-2012.
