You think he had the time to implement a whole new playbook in 3 days? We probably won't see much of a difference for a few weeks in terms of new formations and such, and even then, who knows if the players we have will fit into what he wants to do with our offence(He may need some personnel tweaks during the coming off-season).
We will probably be seeing the same plays we have been all year today, but what will change is our offensive philosphy(hopefully less conservative). I expect a few deep balls today.
