I wouldn't put a dime in Tyson's pocket. I never did even when he was champ. A lot of his fights were garbage. The fights with Bruce Seldon and Michael Spinks especially. Guys who simply quit before the bell even rang. Tyson was a great intimidator but anytime he couldn't scare somebody, he got KTFO! He's never gotten off his back to win a fight.
I think, despite his skill, he was a bully and he couldn't handle it when somebody stood up to him. That's the bully mentality.
