Mayweather not ever tasting the canvas, is down to his masterful defence, not this apparent iron-chin he has.
floyd sure can take a punch, i beleive the only way to knock him down is with a sick counter punch and catch him off balance (if hes ever off balance that is) [ame]http://www.youtube.com/watch?v=Ru6OpUosanw[/ame]
Although it's hard to determine, I would say he has an ok chin. That's all. Not great, and certainly not iron.
He has a good chin, amazing conditioning, and incredible reflexes to grab Mosley's arm to keep himself upright.
It will be interesting to see what happens next time Khan gets bounced around the ring like that as he fired (not too mention cheated, lied to and stole from) possibly the best conditioning coach in boxing today. But on topic Mayweather was in tip top condition and has a granite noggin!
Good balance, fast reflexes and good footwork. He also seems to have good timing when he's hit with certain shots. Like leaning back, which softens and minimises the full force of the shot. That's probably one of the main reason's why Floyd's a nightmare to catch flush....
Spot on, though that's not always the case. Hearns was conditioned perfectly yet couldn't take a punch well enough, some cases can be different.
I was very impressed that he stood up. To stay up when your legs give up on you takes a strong will to overtake what your body wants to do and say "hell no, were staying up."
And why we rarely see him hurt. But the few times where he has been caught flush, he's been rocked badly in most of them.

He toke some very good shots from Barkley in the rematch and went the distance though he got sparked in the first fight. I think people underrate Tommy's chin. It's not as bad as people make it but it wasn't above average either.
