I don’t think there is any chance this happens, but Texas A&M could pay Campbell $20M a year and give him a chance to return to his home state.
You don’t have any insight into anything else about how this season plays out - would you take that deal right now?
Sometimes coordinators are better as coordinators, and HCs as HCs.
Campbell is a good HC because he is a motivator, and lets his coaches coach. He’s still a football guy, and still holds people accountable, but he leaves them fairly autonomous.
I’m not certain that adding the HC responsibilities would make Ben Johnson a better coach. In fact I think it would burn him out and his game plans wouldn’t be as tight.
