The Brisbane Lions experienced tremendous success to start this century off going back-to-back-to-back (2001-03) before a slow decline that saw them lose the 04' Grand Final and only make the finals once since (2009).

In order to make its way up the ladder, Brisbane were forced to make personnel changes including many players who have gone on to lead successful careers at rival clubs.

Either seeking opportunity elsewhere or falling out of favour with the coach/board, players opted to change the Lion that was originally on their jersey, to something else.

Some trades worked out for Brisbane, but as most people are aware, a lot didn't.

Here are the top 10 players Brisbane have let go since 2003.

8. Jason Gram

Not many people are aware of this, but dashing half-back Jason Gram was on the Lions' list during their golden era which saw triple premierships in the early 2000s.

He was picked at 19 in the 2001 draft but could only manage to play two games in season 2003.

Gram was recruited by St Kilda for pick 23 but was able to play seven games in his first two seasons there.

2006 was the turning point, with Gram playing 23 games, including the elimination final loss to Melbourne.

From 2007 onwards, Gram was a regular in the Saints' outfit where his run off half-back and his penetrating kick contributed to the team's rise up the ladder.

He was a pivotal part in the losing Grand Finals in 2009-10 which saw the club come extremely close to ultimate success.

Gram finished his career in 2012 with the Saints after playing 156 games in the AFL.
