Beffore we go ahead and annoint Ortiz "The Next ...", it would be worth acknowledging a few things, the first and foremost being that he can't fight much. The biggest reason he won last night is because the guy he was fighting had no plan, and even at that he managed to exploit two of Ortiz's biggest flaws and knock him down twice. And those same two openings were there all night, as Ortiz doesn't seem inclined to learn.
He gets all his weight to his right side and pushes that left hand out there- honestly, a good fighter would be torn between countering his left with hooks all night, or stepping to the right, or simply pulling back, and blasting him with right hands. His defense is non existant. Putting him in with Mayweather would be a mis-match of epic proportions, and, shot or not, I think Mosley would smash him worse than he did Margarito.
