I would favor Chavez. Great fight though. He would have to apply smart pressure to ETM. JCC knew how to do that. When he did get caught he had that titanic chin. Getting inside and working the body with precision. I don't think it`s a blowout though. Arguello would have his moments and win some rounds as well. Chavez had heavyhands. Maybe not the one punch power. He made guys quit on their stools. Chavez W15
A guy named Chappo fought at LIGHTWEIGHT not Jr. Lightweight. And while Rosario could crack AA still hit harder.
