The issue for him is attitude. He has had it all handed to him and didn't have to work. If he can sort that and keep his weight in check I think there's a talented player there. He would have killed it through the 2000s.
I think our attack being a bit different this season has affected will the most. Not as many sweep plays seem to be getting a run which is good I think as a whole. Seems to be playing a lot more direct through the middle to me.
