It won’t happen but I definitely don’t think it would look like a dick move for a new AD to fire a coach with back to back 20 loss seasons. No decent coach is going to be scared it could happen to him.
I’m not saying they would be scared it would happen to them. Let me put it this way - If you had a friend or colleague who told you their boss was a dick, would you want to pursue a job with that boss? The college coaching world is a small one, and coaches talk to each other, a lot.
