He's sparred with a few mediocre heavyweights n done well. He even taunts them while sparring. I think the klitschkos would be too tall for him though but I don't think it would be as one sided as people may think. Mayweathers got good movement n would be a pain in the backside for either brothers who are slower n not as mobile. Mayweather may lose but I don't think he'd be dominated. Nikolai Valuev would be waaay too tall for mayweather to land a head shot lol he'd win with just body shots... Most probably the jab to the body. Valuev is very predictable.... Jab, jab, jab... Jab, cross. People may think I'm crazy for saying such things, but I have a lot of faith in mayweathers ability
Against the average heavyweight boxer yes. He would only have problems with people like klitschkos haye etc. Hes one of a few I think could survive. Hes hard to hit and heavyweights will be even slower. He definitely couldnt knock them out, but if the heavyweight rushed into him and then let bombs off i think it would be easy for them to knock him out.
Mayweather has a glass jaw. Chop Chop Corley had him hurt bad, ready to go. And Sugar Shane had him ready to go as well with a shot that didnt land properly.
He will go the same way as Roy Jones Jnr, watch and see.
There are weight classes for a reason.
