too early for this...these fighters are still young and i think they haven't even reached their full potential. why ask who is the best when they're not yet on thier best?
1.Juanma
2.Gamboa
3.Rigondeaux(I know he probaly is the more skilled of the 3, but beating bums doesnt cut it, Juanma is a 2 divisio champion and Gambao atleast has beaten world champ, Rigo have a lot to prove as a pro still)
