I know one thing: Ray Mercer is not going down from a head punch. I think he's got one of the best chins in the game.
You know if you want to be a boxer the first time you get hit on the nose.
Rocky Marciano had such guts and heart. He was something special.
Make no mistake, the days and hours before going into the ring can be stressful for any boxer. The bigger and tougher the fight the greater stress, But if a boxer knows he's stepping out of his league it's even worse.
Kell Brook has a lot of heart. He showed it against Golovkin and when he came over here to the States and fought Shawn Porter. He's a real warrior in the ring.
Listen, anyone in the heavyweight division in the top ten, there is no easy fight. I don't care what you say.
I've boxed on with cuts, broken jaws, everything.
I knew Avila was going to be a tough, strong opponent. I cracked him a few times early, but he kept bouncing back every time. When I knocked him down, I could tell he wasn't hurt and was impressed by his toughness. He brought out the best in me.
Joe Louis is the hardest puncher that I've ever seen... He's a good man. Anyone who plans on beating him had better know what they're doing.
You don't knock Ray Mercer out with one or two shots. You have to make him quit.
