Firstly let me say that I do NOT think Floyd Mayweather is going to retire. He might go on a well-deserved hiatus, having made plenty money and just won the biggest fight ever, but he is not gone for good. That man is born to fight, its all he's known, and once the dust settles he'll miss the competetive buzz that he got from fighting and come back for more. No doubt about it.

But it could be a while before he comes back, which leaves us plenty of opportunity to speculate as to who might be the one who can beat the pretty boy. Who's got the right style to put a 1 on Mayweather's record? I pick Ricky Hatton or Shane Mosley. Floyd didn't like being put under pressure by De La Hoya against the ropes, and although De La Hoya is much bigger than Hatton, Hatton is a total pressure fighter. He'd have to fight like he did against Kostya Tszyu, but I think his style gives Mayweather nightmares. Ricky leaves FLoyd no room to work by constantly marching him down and out-punching him. The other pick is Shane Mosley. Shane has the handspeed and reactions, even at 35 years old, to elude Floyd's pot-shotting and trickey. He's the only man out there who can match Mayweather in terms of skill, he wont let himself be outboxed in the centre of the ring like Oscar was the other night. He has a fast flickering jab and big power, he could hurt Floyd.

Those guys would both start underdog, no doubt, but on their day they could do it.
