Will May 1st be.....Mosley's first?

Mayweather does not hit hard, does not hit often, and Mosley has taken shots from fighters incomparably harder hitting and more often hitting than Floyd.

10-20%, any well placed punch can crack a chin( Via Hatton ), however I very much doubt this will be the case.

Mayweather landed a perfect shot on Hatton there, but I don't think he has anywhere NEAR enough pop to floor Sugar Shane. Shane is a tough mother****er, he's going to keep coming to the end, even if he can't get close. Did you see the exchanges he had with Cotto and De La Hoya? Vicious. Floyd doesn't have the power like they do, he won't stop him. I voted 10%, though, because anything could happen. Floyd might sneak a baseball bat into the ring...

i think Mayweather can KO Mosley, it only takes 1 punch in boxing

[Chief2ndzOnly!]

I say based on styles and ring habits, Floyd has a 60% chance of getting a stoppage against Shane.

Not against a granite-chinned warrior like Mosley. Mayweather would have to bomb him for 12 straight rounds to do any damage.

Haha. Somebody voted 100%

Anyway, I think 10% considering Floyd's lack of KO power at Welterweight makes it highly unlikely, but it could happen. Even if Floyd does dominate Mosley for the whole fight, I highly doubt it'll be a knockout.
