This is a good post. He very well may based on the pressure. That was one of the first cracks I saw in Butch. Dude was screaming and kicking up dust in some pretty common situations. I like passionate coaches (Did you see Saban rip into his OC after 2 failed roll out passes the other night?), but Butch was going off at times when I would have expected a great coach to be pondering strategy.
I've been in somewhat similar leadership situations. You cannot discount the effects of pressure. Muschamp is a good example. At TX in waiting, he was considered a top coaching hire in the nation. Did a phenomenal job this year.
