I don't buy the 'structure' argument that people are using to justify keeping Miller in the side.
If by 'structure', people mean 'a tall that can bring the ball to ground level at around the 40m mark and take some attention from our No.3 tall', then OK I get it, but sheesh it's not hard, even Hislop can give you that and he gives you a bit more at ground level.
The 'structure' is provided by the coach, it's a role, not a player, and as MT says Post should be given the chance at that role now then Griffiths when he is ready.
Whilst I appreciate his efforts in filling the role when needed, it does have to be said; Miller is as slow as treacle, he looks big, but he has got custard arms and a jelly heart, and if the ball is under his waist, forget it. One of the worst kicks in the comp. Drop him.
