I thought he was a little too hard to reach with his no nonsense attitude, and I think it bit him in the ass, because he's so straight line. He didn't even allow cursing at practice. Not sure I would have liked to play for him. He might end up as another case of a guy that is better suited as a coordinator. A head coach, IMO, needs to be accessible, approachable, and needs to have some flexibility with certain players. Not everyone is the same, and if you try to make them that, they will not play like themselves.
It's like having a GF, or wife that changes you, and then one day looks at you, and says, "I don't like you," and then you say, "Good, because I'm not ME anymore."
