I think you're incorrect about that. Dorsey is an "I'm the smartest guy in the room" type guy. Remember the temper tantrum? Yes, he is a bright young mind. He is exceptionally smart. But, anyone who thinks they're so much smarter than the rest is bound to fail. You also typically lose the respect of your subordinants too, because you simply do not listen to their input, or put them in the best position to take advantage of their strengths. Instead, you force them into positions that suit you.
So, Dorsey tried to show-up McD and the other coaches every day. He also tried to do the same to his offense.
Buh bye, Kenny!
