I would also like to add that I noticed another difference from their first fight, Cotto was holding when Margarito got close and smothering his work. Margarito has great uppercuts to the body on the inside which were the downfall for cotto in their first fight. The same uppercuts that seemed to hurt Pacquiao in the 8th round I believe. So the holding tactic that Mosley used to take Margarito's most effective punches away also worked for Cotto.
