Of all the fighters in the WW division, Margarito is by far the most dangorous for Cotto. I'm from PR and am a big fan of Cotto but as was said before, the hight and reach advantages, the fact that Margarito knows how to use his hight and Cotto's slightly questionable chin make this a tough task for Cotto.

I actually think Cotto has a better shot at Mosley. I hope Williams beats Margo because, even though Williams is also a tall guy with even more reach, he does not use his hight well and likes to get close and brawl more. He is sometimes compared to Tommy Hearns but he fights nothing like him. Cotto would beat him I think.
