Sorry but he's been the same coach for as long as he's been here. Clearly enough players, coaches, administrators, and fans have been able to put up with his berating of players, for him to be here 20 years. This will not bode well for his defense...that many people agreeing to a behavior that is negative for the outside world isn't going to help his credibility. They have accepted that is how he is. He coaches them very hard and holds them to a high accountability/standard. I agree there are different ways of being a successful coach, but being a softie is not necessarily the "right" way. Even within a team, you have to be able to manage certain players differently.
Obviously I would have a huge issue of him being racist, but I just don't see how that will be proven. And without this being too sexist, I've always had more of a problem with how he coaches his players, because they are females, WOW, remind me never to have you coach my girls...they don't need special treatment because they are young women...as compared to if they were men's players.
