The guy probably spent a few days in Auburn and thought "OMG!- what I have I gotten myself into?!?" He probably called his agent and said "Get me outta here!".
I thought it odd when they hired the guy and more odd that the guy even took a college job. He has been a special teams coach in the NFL for years and is highly regarded. The hire never made sense to me and their fans should not be surprised of his picking up and leaving. Not so much to do with that cesspool down there, but the guy is an NFL guy.
