I think you can get away with it more at the college level because you only have kids for 4 years. It's when you try using that against the higher ups and people with power that tend to stick around longer than that that the situation becomes untenable.
That's why I think someone like Buzz and some NBA coaches like Scott Skiles or Tom Thibodeau are better suited for the college game. Some do tend to grate faster than others, though. Last year it sure looked like Buzz lost the team, and that his underdog mindset didn't resonate with everyone.
