Yes, he did overvalue himself. He hired Clawson from Richmond, which was a lower-tier school, thinking he'd take him under his wing. Fulmer's ego couldn't handle hiring an appropriate, established offensive coordinator.
Flash forward to Fulmer's AD tenure. We had Mike Leach lined up as HC, but again, Fulmer couldn't stand the thought of an air-raid legend calling the shots. Yet again, Fulmer's hubris led him to hire someone unqualified. He thought he could mold Pruitt into Fulmer 2.0 rather than hiring the most qualified candidate.
Fulmer's strength was recruiting, and his loyalty to the university. In Fulmer's view, he was a great offensive mind. In reality, the great offensive minds were coaches like Urban Meyer, Bobby Petrino, Steve Spurrier, and David Cutcliffe. Had he put his ego aside in hiring an elite offensive coordinator, he could have survived another 5 to 10 years.
He also kept gaining weight throughout his tenure. Yes, there are plenty of fat coaches, but it seemed the more weight Fulmer put on, the slower his football mind worked.
I do appreciate the natty and SEC championships he gave us. Nowadays, I want him as far from the program as possible.
