Margarito is bitter. For the sake of an edge at the very least against Mosley, he has cast what will be a lingering (if not permanent) doubt on all his accomplishments, and he knows it. There will always be the specter of the gloves in considering at least his past victories, and he has nobody to blame except himself and/or his trainers. Was it worth it? They say sticks and stones may break my bones but names will never hurt me, but in actuality, it's damage to one's reputation that is generally more lingering. Long after he's healed from the pounding he took against Pacquiao, his reputation is still damaged from the handwraps incident.
He may have as much to prove as Cotto. Cotto didn't strike me as at all afraid of Margarito. Just confident and classy. I thought that Cotto would be more pissed off than Margarito, but that may not be true. Ironically, despite the result of the first fight, Cotto seems to be more at peace with it than Margarito. Margarito seems to me to have almost a little kid's mentality of protesting his innocence in one matter after being caught as guilty in another. It's going to be very interesting. In the interview, I see Cotto as very focused on the job at hand, and Margarito possibly not being able to have a handle on his emotions, which may hurt him. But it may not, as his style is very wide-open, too. But I do see Margarito's mental state possibly being subject to exploitation by a smart fight like Cotto, a la Leonard-Duran II. I thought going in that Cotto will win the rematch, and the interview doesn't change my mind, but that may just be confirmation bias at work.
