Cotto destroys Margarito I believe. I love the body work Cotto puts in. He is one of the freakishly strong fighters that has power above his division I believe. Margarito is a top 10 solid fighter, however I think he will have to answer some very hard questions whenever he gets in with Cotto.
Margarito had a bad outing against Clottey, and that happens...still a cracking fight. However I think Cotto is really something special.
As far as Margarito beating Williams, VD is right. Sharmba is not a good indicator as to Paul's place. To be a top contender in the WW division takes a little more than that. Who knows?? Unproven, however he has been brought up very slow it seems.
