Margarito got caught trying to cheat before the Mosley fight. How can anyone positively clear Margarito of any wrongdoing in the Cotto fight, which had already happened? Why would Margarito only start cheating against Mosley after "never having done so before"? These are all valid questions. The immediate and extensive damage to Cotto's face is a pretty good clue that is wasn't just due to volume of punches. Sure Cotto has been cut before... but this was far beyond any of those times. And like has already been said... Margarito's power "post-Mosley" has proven to be way off. Who knows how many other fights he won using those plaster casts? And when Margarito had Cotto in front of him again... and PROMISED to knock him out so everyone could see it wasn't the plaster casts.... he didn't. He hit Cotto enough that had it been just his power the 1st time around... he would've knocked him out in the 2nd fight also.
