If I'm an OC candidate this is the absolute last program I would join in the FBS. A big public stink scapegoating this guy is only going to make that situation worse.
I'm sure he knows he's gone. He's probably been job hunting the last month. He's a year off from a Broyles award. This needs to be as low key as possible or who is going to come in here thinking they are going to do any better.
You don't want to fire and humiliate the guy right now. Horrible PR. Who in their right mind would come and replace him? Help him land on his feet and move on.
