My own concerns are due to the forward line, not the backline.
Does anybody not think that Daniher, Hooker, Stringer and Stewart is too big from a defensive forward / pressure point of view? It’s a huge part of the game now.
That’s what’s behind the Hooker back thing, for me anyway.
In a word, no.
For a start Stewart would be second only to Tippa for defensive work rate and effectiveness among the forwards. While he doesn't do a lot of chase down tackling he does heaps of relatively unrewarded running in the zone take up position. That's simply an advantage we get with Stewart.
Whether or not Stringer is a problem will depend on which version of him we get. Changing the structure of the forward-line to accommodate Stringer was never an option from my perspective so he's going to have to play the way we need him to play.
The other thing is that defensive pressure is really only required at the Richmond/Dogs level if you can't score efficiently.
