Does Antonio Margarito get credit for being the only man who convincingly beat Sergio Martinez?

Truth be told Sergio isn't the same fighter he was 10 years ago, no fighter is. sergio has grown into a much more confident fighter. Sergio sits down on his punches better and plants his feet as he's throwing punches instead of be off balance as he was for the Margarito fight. I was there and saw some things that Sergio was doing that just didn't make sense and I watched the fight Saturday and he looked like a completely different fighter. To tell you the truth,Truth great question.
