Paul the Punisher Williams. I know he is not completely overlooked, but I see SO much more about so many other fighters that aren't even active than I do about the Punisher. The guy is a great fighter and will fight against anyone in several weight classes.
I'm going to say Timothy Bradley for active. It's funny when people say Hatton was the man at 140. I can't see him beating Bradley. He is one of the hardest working fighters in boxing, just not really acknowledged.
Felix Trinidad Active Much of the champs in the jr middle division exept Williams and maybe Martinez.
