He did basically everything wrong. Tried to bury Penn State (as I think a few of you may be aware), then gave a pass to UNC on their fake classes for athletes issue (something which actually was relevant to college sports), then utterly ignored sex abuse cases at OSU, Mich and MSU - situations where there were hundreds of actual, documented, CREDIBLE and SPECIFIC reports of abuse which were systematically ignored and suppressed.
Seemed to me that after the anti-PSU jihad blew up in his doughy, pale face, he spent the next few years hiding in his office and quietly collection $X million / year.
Incompetent would be the kindest term I can come up with for him. Malevolent POS is closer to the truth. Parasitic, self-promoting jackass also applies.
