The big question is - where was Thomas?
If Thomas is injured then Miles elevation should be an almost fore-gone conclusion (if it wasn't already!) I was always surprized that they choose Thomas over Miles at the beginning of the year after their preseason form. Imo Miles showed as much inside as Thomas but had better run and disposal. He also has great goal sense and the most important thing of all - determination.
I don't believe that Griff will be played alone side Vickery and Jack. It makes our forward line too tall and reduces our forward pressure by too much. With Vickery playing a much improved game it may have saved his skin. I actually think Griffiths offers us more than Vickery even if they are both playing at their best.
Newman's injury is interesting. What is his actual role? Is it half forward? I would place S.Edwards in this role, move Conca to the wing and then put Miles in the center.
Either way we have two weeks to wait to find out.

By the way - great write up Gigantor
