I think if Cotto wins, it reinforces his position as the number 1 welterweight in the world. If Margarito wins...then I don't know.

Actually I do know, if Margarito wins then I would have Paul Williams as the world's number 1 welterweight. He beat Margarito pretty decisively, and he lost once just like Margarito only he avenged his loss in 1 round. Margarito beat Cintron who he had already beat before and who I didn't rate higher then Quintana in the first place. That win didn't do much for me except give Margarito a good looking win in a good fight before a great fight. Don't think it meant much in the way of rankings. Certainly not more then Williams' destruction of Quintana.

If Margarito were to win (not happening but I'll humor everyone here), then I think a rematch with Williams would be in order and unless he shows something he never has before in this Cotto fight, I think he loses even more in a rematch.
