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!

4. Mitch Robinson

Another from the category above, a club who genuinely needed a hardened body to help Patrick Cripps in midfield.

In fairness, Robinson wasn't exactly a model professional off the field when at Carlton and he does come with some baggage, however his training work ethic has never been questioned, he leads by example and works himself into the ground.

Having turned his career around in Brisbane, it's not a stretch to imagine that the Blues would love him back in their squad this year.
