How the **** did Duran cut so much weight? Chaves was smaller and couldn't fight effectively at 147. Duran beat fighters JCC couldn't possibly even compete against, let alone beat. But H2H at the lower weights, it's closer than what most people make it. JCC's chin was made of some unknown metal.
JCC would smash him up, Duran and Pryor are the most overrated fighters in the history of the game. He'll win this poll by a long shot though.
