Interesting.....i think Williams would be the more awkward because of his height and reach. A genetic freak really. He's decent....i expect him to beat Margarito. Besides landing a lucky punch i really cannot see how Margarito is going to beat Mayweather. I know he has the edge in power but i don't see him landing anything clean. I suppose anything can happen in boxing...i just don't feel thses 2 guys are the main threats to Mayweathers '0' on his record.
