Yeah, I did. But all the asshole coaches I had were losers, and so were their teams.
I had a couple of coaches who were complete pricks, and their teams absolutely were winners. But they were substantial human beings.
The best coach I ever had was neither. He wasn't a rah rah by any means. He was all business and we barely knew him, but he knew his shit and we respected him. He let his assistants be the bad guys.
He's still an asshole.
