I don't care to see Pac fight anyone besides mayweather. He already beat Cotto and i don't see him losing to Margarito even though it would probably be a fun fight to watch. Margarito's reach has to be a HUGE amount over Pac, but Margarito needs time to wear down his fighters with his shots. I don't see him finding Pac even close to what he would need to be effective. He'd be a punching bag for Pac, but would obviously keep coming, which would make it fun to watch, but i don't have a doubt on the outcome.
