The thing I kind of took from Mathis and Olaniyan's comments was that they weren't comfortable with the atmosphere or environment at UM. I think that's legit and a personal preference, but it's not something that should be ignored. It seems like our coaches are tough and yellers and, god forbid, happen to swear from time to time.
People respond differently to different types of instruction / criticism. There are people out there who do well in a high pressure, high intensity environment, and people who respond more to a calmer, more logical approach. I don't think one is necessarily right or wrong, but we have to realize that maybe this staff's style just isn't for everyone. If you're a guy who likes a calmer environment, I don't see why you'd sign up for four or five years of yelling and craziness. Just like those guys probably wouldn't ever sign up to play basketball for Bob Knight or Tom Izzo.
