I understand what you are saying, but it misses the point. Eddie's drinking didn't matter, and Gillispie's drinking didn't matter. It's like saying, "I can't believe they would hire another blue eyed football coach after the mess Mumme got them into." Next to whether the powers that be believe a guy will win or not, his personal habits are about as important as his eye color.
That comment only mattered because his teams weren't very good. Being a "butthole" only mattered because his teams weren't very good. I doubt you can identify a more arrogant yankee prick than Rick Pitino, c. 1990-1996, and there are still a good number of UK fans with alters to him on their mantle because the guy won. Think that New York Catholic Italiano was an ambassador for the state of Kentucky? Think saying that his job was winning games instead of politicking would have nailed his coffin?
The list of coaches that are jerks is long, indeed. Arenas get named after the ones that win. The ones that don't wind up in contract disputes after their dismissals.
