Williams is the obvious answer. I'd say Floyd beats him too. And depending on what Cotto has left after the first fight I wouldnt rule him out either!
Paul Williams already beay him at Welterweight and when Margarito gets the balls to rematch him at Welterweight he will get schooled again. PBF would also school Margarito and make him look like the slow flat footed plodder that he is.
Its a really , really dark and old .02 CENTS with a little rust attached to it . Found down at the bottom of a trunk stored in an attic.
Good thing this is boxing and to beat a guy you don't necessarily have to "Stop him from coming forward"....you just have to out box the guy.:good Hatton wouldn't be able to stop Marg b/c they have similar styles and going head to head, toe to toe with Marg is a loosing battle...but boxers, versitile fighters like Floyd or PAC...definitely have a chance. More so Floyd b/c he's a cool customer and doens't get rattled or forced into a "FIGHT" easily....PAC's pride could hurt him in that regard if he faced Tony. And of course Paul or Josh have a chance....Moreso Paul IMO but you can't count a two fisted Joshua out either.
