Coaches like sloan, Larry Brown, George Karl aren't the kind of coaches that these younger hard head players need because these coaches have Huge egos of their own and our out to prove that ONLY their way works. When you have a player that very emotional like D.cuz you need a coach who is going to be able to establish a relationship first and still hold them accountable.
A guy like Mike Woodson, Nate Mcmillan, Mark Jackson etc. Guys who have earned their stripes are respected and can get through to a player and make him work without having that I'm bigger than you attitude.
