Well its alot easier to fight Margarito at 151Lbs for a paper belt, as opposed to Marvin Hagler at +10lbs a weight youve never fought before. :good "Oh but he started off as a mosquito"...So did everyone else when they were 16 in the amateurs.
Gonzalez/Joyi seeing as the disparity between the little guys is smaller and they are class fighters. They could probably win titles at light-fly/fly definitely. Apart from that, Gamboa? If he improves his defence maybe, otherwise he might be getting sparked at 135.
