No doubt about it, in my career Ron Lyle hit me the hardest. One time he hit me so hard I didn't see it until I saw it on film when I woke up!
There's never been a boxer better than Joe Louis. You'd take one shot from him and you were sure he'd have seven or eight more coming for you. Certainly Muhammad Ali was the greatest man ever to fight, but not the greatest boxer.
No one is the same after I fought them - Hearns, Duran, Leonard. All of them.

The heavyweight division is the division that historically always drives boxing. It's the flagship. That's because even if a guy is a big underdog, one punch turns everything around.
I've definitely changed as a person because of professional boxing.
I think on balance, Don King has been bad for boxing. I think he's done some very good things and I think he did a heck of a job of promoting Ali but I think I could have promoted Ali.
I just felt I had done enough in the sport to put my stamp on boxing.
Every fighter, when they box, wants to leave a mark in their sport, or a legacy, and I managed to do that beyond my wildest dreams.
Kenny Norton hit me so hard that it still hurts. Now there was a case of two fighters who did not like each other.
