The number of injured players and walking wounded after just 2 games is too damn high!
EDIT: Also, at a pro style replacement is more of a necessity than a stubborn preference at this point. I don't think this program can survive another 3 year rebuilding project. The one bright spot, recruiting, makes that even more of a bad strategy. It is what it is at this point. Unless Harbaugh or other HC version of Nussmeier suddenly shows interest it's probably ride or die with Hoke, even if the team doesn't improve much this season.
