It happens every season, players get traded for nothing or let go by clubs who deemed them unworthy of a spot on their list, only for them to turn their careers around or fire in a new environment.
For the purposes of this exercise, we're talking exclusively about players who were delisted or basically pushed out of their clubs, so big names like Joe Daniher don't apply here given the Dons would have gladly kept him.
We take a look at a handful of players who are showing their old clubs just what they're missing out on!
2. Josh Bruce
Another decision that you'd think the Saints are probably regretting right now. While last year Bruce hardly set the world on fire, this season he is flying, and not just for marks either.
Sat fifth on the Coleman Medal leaderboard in a deadly Dogs forward line, Bruce spent the summer training with best mate (and Saints Co-Captain) Jack Steele, putting a firm focus on his fitness.
The results speak for themselves, and you'd have to think given the Saints woes in front of goal that they could use Bruce's experience and form in their current forward set-up.
Another of the Saints blunders but understandable, the money required to pay Dan Hannebery to rarely play had to come from somewhere and Bruce was one of the casualties. Kudos to the Dogs for seeing his talent and making use of it.
