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:

3. Dale Thomas

A high draft-pick bouncing in with his long blond hair epitomises 'Daisy' Thomas seeing his first year open the eyes of anyone watching the footy.

A significant part in the 2010 premiership side, 'Daisy' was ready to take his game to the next level but constant injury and a pull from Carlton coach Michael Malthouse saw Thomas leave to go to the Blues at the end of the 2013 season.

Still there currently, Thomas tries to use his experience and skill to help develop the young players that seem to be filtering through the Carlton rooms.

Entering his 14th season, 'Daisy' has a little bit left to give, but some would say not much.
