Duran has quoted before that at 135lbs in a mythical fight with Chavez he believes at 135lbs Chavez might of edged him, but "Over 135lbs his ass is mine!" nobody drops Chavez at 135lbs and Duran might get dropped, but nobody leaves him there either. i might still give a slight edge to Duran with that right hand that he had and few could outhustle Chavez, but i think Duran is one of the few. A real madman he was
Durans agression would work against him vs JCC. Chavez would work the body and pound it like he did to everyone who came to FIGHT him. The guys who came to fight him got their asses handed to them, the ones who wanted to survive lost but didn't get beatdowns. I cant see Duran out conditioning JCC or out Chining him. Chavez could crack too and would get in the better counter shots. Chavez by dec or tko if it were a 15 round fight.
