Fighters/Champions that could have been great!

I say this all the time when threads come up about who never fulfilled their potential but Joan Guzman is the ultimate choice in the modern era. He could have been a 4 or 5 weight world champion if he'd dedicated himself to actually making weight for a fight. Having a promoter with better connections would have helped his cause too.

Is Guzman still fighting?

@Master, yes he technically is, but his last fight was October last year.
