Froggy would be miles better than Dizz there but right now he's too valuable where he is.From the look of it, I've probably been more optimistic than most to the idea of Diz playing up forward. That third tall/mid-sized forward position is a problem for us, we don't really have anyone that fits there. It hasn't worked with Gardiner so far, but I don't really hold that against him, I think if the rest of our forward line was functioning anywhere the consistency or skill level we expect, things would be looking better, but it's clear we need to re-think things.
I don't think Rayner is the answer, He'll just be another body caught up in marking contests, and at this point he really needs to be playing predominantly midfield minutes. Diz doesn't really deserved to be dropped in my opinion, but I wonder if it would be worth swapping Lester with Gardiner. He's more likely to provide the forward pressure and tackling we're missing, and has the footy smarts and skills to still work on the lead or as a link up player.
Either way, what's really needed is a change in game plan more than any particular change in players, although I think a few players could do with some time in the VFL to gain confidence, more than anything else.
Just a little fetish of mine but I don't believe in taking players away from where they're good value and performing well every week. Rather move someone who's a liability where they are.
