well this is how i see it

Cotto beats everyone there except Margarito. I think Margarito has Cotto's number

Margarito beats everyone except Williams. Again William has Margarito's number

I think Williams beats everyone except Cotto and Clottey. yes i said Clottey

Clottey beats everyone except Cotto and Margarito

Berto only beats Cintron (atleast at this point in his career)

and Cintron looses to all

maybe i'm just a little nuts
