I am not that concerned about any playcalling issues because we have the Mad Scientist and well, a Mad Scientist is mad. Means he will do some insane things from time to time. In the end, though, he is going to invent flubber, so I am content.
I think RR is on a quest for a replacement for Jeff Casteel. We know of West Virginia's surprising competence on the defensive side of the ball during RR's tenure, and the Shafer and Robinson moves show that RR is only an Offensive Mad Scientist and searching that defensive counterpart. To that end, he took what bodies he could from the defensive staff at WVU, but reached for some other people, notably Shafer and Hopson. Both those reaches appear to be, well, reaches. Given what I now understand is a fledgling, paper-thin defense, GERG appears to be serviceable. Until RR gets the defensive group he needs, I am afraid we are in for a lot of angst.
I tip my hat to Sparty - they played exactly desperate.
