The thing is if Berto wants to continue taking steps up in competition where else can he go, I mean I would be hesitant to call Cintron, Judah or Clottey even lateral movements in comparison to the caliber that Collazo is.

Of the guys at the top of the WW division, Margarito is out for at least a year, and the wrong style for Berto IMO, at least until he stops opening up, it seems Paul Williams isn't fighting at WW anymore. Both Mosley and Cotto are on a similar level, but at least againt Cotto IMO his odds are better because at the very least if I am totally overrating his skills which I don't think I am he has a punchers chance which nobody has against Mosley who has an imprenetrable jaw when it comes to punches at least. Cotto is vulnerable to Berto's best punch, the right uppercut, and Berto has a huge speed advantage on him. Mosley is impossible to hurt(Barring a headbutt), he's very fast and still has good reflexes, he isn't as natural of a fighter as Cotto, but like he showed against Collazo he can still box on the outside if he needs to.
