Neither, honestly.
He was always a bit of a hothead and I assumed that whole Wisconsin incident was on him until I actually saw the video and realized the other head coach had grabbed him first and then that idiot assistant had come barreling in there shoving people and screaming then put his hands on one of Howard's players. He shouldn't have cuffed him right then when things were already running hot, but he didn't start it and there were multiple extenuating circumstances.
It's more just watching the way he manages game situations, how he interacts with his players, the things he's saying spontaneously when somebody sticks a microphone in his face. His sense of awareness and his demeanor have had me unconsciously nodding my head at him. I just never expected that to happen.
