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:
6. Heritier Lumumba
After a slow start to his career, Lumumba only played 13 games in his first two seasons. However, a surge toward the top saw the Pies make the preliminary final (2007) against Geelong where Lumumba played 23 games that season.
The versatile half-back who is quick and agile was seen as a force to be reckoned with and continued his consistency and form down back until his last season at Collingwood in 2014.
He played every game in the 2010 premiership year and was an integral member to the side's success.
Having fallen out with coach Nathan Buckley, Lumumba took his chance to leave and headed to Melbourne, where he played 24 games in two seasons, his last season only consisting of five matches.
