I just watched Margarito and Cintron 2, and besides his workrate there is nothing impressive about Antonio Margarito except his chin. He doesn't hit ridiculously hard, he's as slow as Baldomir, and he throws the widest punches I've ever seen. If he was in there against Mayweather he wouldn't be landing 15% of his punches, and no he would not break Mayweather down, I could see Cotto's power and sharpness maybe doing it, but Margarito doesn't have the strength or power to hurt Mayweather nor does he have the footspeed to keep up. This fight would look almost exactly like Mayweather-Baldomir except that Margarito would be throwing more punches. I see Vernon Forest, ODLH, Cotto, Mosley, Mayweather, Spinks, maybe even Mayorga all beating Margarito at 147-154... he is way overrated on this forum.
