The coaching graveyard said more about the institution's commitment to sports for many years, mostly prior to say McCarney. It drives the bow-tie crowd bonkers, but the bigtime sports and football in particular are HUGE marketing tools for the university, and a built-in mechanism for alumni to stay connected. They are obviously a big net benefit for the community as well.
The expectations here are so much lower, and the fans are quite a bit more patient and loyal too. With the facilities and budget improvements, it's a lot better job than it was when Walden had it and McCarney took it over. A guy that goes .500 overall and .400 in conference here would have a job for life. That's almost unheard of in bigtime sports.
