If Cotto or Pacquiao were to fight Margarito the way Juanma fought Salido I think they would get KO'd. Mexican fighters have a lot of heart and even thought sometimes they're outclassed they're never short on heart and toughness. In a toe to toe fight Margarito would beat Cotto and Pac IMO. Well he can beat Cotto for sure because he proved it in the first fight.
pac had loaded gloves for the margarito fight as shown on video
Hell yeah that vid is still up...I will dance to that homie!!
