If he fought like that against cotto las nite, he wouldn't stand a chance against the Puerto Rican wrecking ball.
I think Berto KO Cotto. Cotto has never had defense or a chin. if Margarito slow ass uppercuts can hit him Bertos would devestate him. Berto can get KO too, but I say Berto KO first based on speed advantge.
I think the fight gets stopped no matter who wins, but after seeing Berto's last fight I'm a bit more confident in a Cotto victory.
