Trading in our game has been more important than ever, with players going in and out of teams, not only in the off-season, but during the season as well.

Therefore, it is pivotal for teams to get it right and identify talent and potential early in the process. This didn't seem to be the case for the Saints over the last decade or two.

Being out-of-favour and wanting more opportunities, players left the Saints in order to continue their career.

Here are the best 8 players St Kilda have traded or delisted since 2005:

5. Brent Guerra

In his second club, Guerra looked to secure a spot on the Saints list during the 2004/05 seasons. After having left Port Adelaide to return home, he wanted to start afresh at a new club.

However, his time at St Kilda was short-lived and was quickly moved on to the Hawks.

The penetrating left-footer was what the Hawks needed and what Alastair Clarkson ordered.

Playing on small forwards and running off the half-back, Guerra found his team as he built a career which lasted eight years.

Fortunately, Guerra was able to experience ultimate success at his third club, as he was a two-time Premiership player (2008 and 2013) and left the league on a high.

Retiring after 255 games, Guerra left his mark in the AFL.
