If Coach K wasn't already on staff, this board would be jumping up and down based on his experience with the Pistol at Nevada, Kapernick being developed by him, etc.
I noticed back in the Kansas game that Grant was always met by Coach K every time, and that continued in the WVU game. I know that he was likely relaying messages from Messingham, but I think at the same time he may have been delivering his own message.
He is a heck of alot more qualified than Mess at calling plays at this level, the o-line is already position named for his offense, and he may have been the guy spending the season telling Mess what he should be calling with the offense in the film room.
I love the thought of fresh blood, but won't be in the dumps if it is him.
