Only coach that I can think of that fell harder was Weis
Rich Rodriquez.
Came a fleas arse from becoming Bama coach. Imagine them hiring him and Saban never being the HC there.
The following year he coached a WVU team one game away from national championship and instead going to bowl game with WVU he bolted for Michigan where he was a massive faiure.
Following that he went to Arizona and that did not work out.
Went to Ole miss as QB coach and OC
Then went to Louisiana Monroe as AHC, OC and QB Coach
Now HC and Jacksonville state
