Say what you want about him but he got caught before the fight not sure about the rest of his career. As for the juice i think he was on that shit as well like every fighter at the top is. Holyfeild never failed a drug test his whole career which extended 26 years so i kinda think the playing field is even there. I am not sure how many people load there gloves maybe that's just as common as the juice is who knows. Margarito would be a champ of one of the many belts most likely the wbo belt maybe the wba belt.
