Well, Cotto "could" beat him... but I doubt it. Cotto's body-punching might prove effective on Paul's slim frame though. I haven't seen any fighter really test Williams' body. Not Margarito, not Quintana, not Winky. If a fighter really puts in the extra effort to goto the body, it might slow Paul's workrate a bit. But as of right now, I think I'd have to favor Williams over anyone at 154 or under.
Cotto. Heavier, more accurate puncher. Mosely. Faster and far more dynamic. Floyd. (If he's not too rusty) Would pick Williams apart. Williams could probably clear out 154 though.
Floyd is tough to say.. Even before Floyd "retired", of all of Floyd's possible opponents, I always said Williams would be his worst matchup stylistically. I'm completely on the fence, if Floyd were to fight PW..
Cotto would get murdered. hes stunned and every fight, and would know what to do with all those punches, plus his defense is no where near winkys, and did you look at winkys face after the fight?? The only person I think can beat him is Kirkland. to much preesure, Williams wouldnt know what to do.
Floyd if he's back to form would pot shot his way to a UD Mosely might be able to do some damage but I'd still favour Williams basically besides floyd and the outside chance of mosely I see no one beating him at 154and under which is why I wanna see WIlliams at middleweight.
I think Floyd would have all sorts of trouble against Williams. He's too freaking long, and hits hard enough to get your attention. Mayweather would have to take some leather to get in close enough to pot shot him, and I don't think he'd make that choice. Williams by boring UD. I think Mosely has the best shot of the three most commonly named. Keith
