Jai Arrow is a fulltime middle and a part time edge forward. He played edge last season partly due to there being no better options but also because he played on with a busted shoulder for half a season by being less busy than usual out wide. That was super tough of him to play on like that but once fixed up, it should be back into the middle rotation I expect where he's most needed and where he is at his best. I expect he will only be selected at edge if other options become unavailable.
Keaon will also be a middle it appears so our main edge stocks will be Murray, Aitken, Host, Schuster and Fletcher. I would love to see Fletcher have a break out preseason and push himself up the pecking order if he can stay fit. Schuster too, sure. He has to aim up but has a long way to go.
Similar to Mellars on the wing. Tass is not a winger and I hope to never see him wearing the 2 or 5. Way too slow and also dodgy under the high ball. Mellars can be Munro 2.0 if he stays fit and gets himself into the clear in the trials.
We're shaping better than many might think.
