I think Pacquaio and Guzman represent his best chances although I really think David Diaz would give him a good battle.

Diaz and Katsidis would be the stuff of legends, it's the kind fight you just know shouldn't get sanctioned on the grounds of excessive violence and brutality.

Of the others out there I don't see anyone. Maybe Amir Khan in a couple years and isn't one of the Peterson brothers a lightweight?
