To win takes a complete commitment of mind and body. When you can't make that commitment, they don't call you a champion anymore.

Liston is like most big bullies, if you can stay away and make him miss for a few rounds he'll get frustrated. Once you strip away that feeling of invincibility, he can be had.

I believe, in my prime, I could have fought with anybody alive.

What could be better than walking down any street in any city and knowing you're the heavyweight champion of the world?

That was a f****g dumb question. If I didn't think I was gonna win, why the hell would I be fighting?!

I'd be conceited if I said I could, but I'd be lying if I said I couldn't.

In the ring, I never really knew fear.
