You see how Katsidis and Diaz got inside and banged to the head? Yeah, Chavez would be doing that more consistently, every round, and to body and head, sometimes in 4s and 5s. He'd laugh off all of Marquez's right hands, and then continue to decimate Marquez's body again. The fight is brutal at every weight, and Chavez comes out victorious more often than not. Marquez gets hit too much, Chavez is far, far to tough.
I'd feel confident in picking a Chavez beatdown at every one of those weights. He's just flat-out better than Marquez and best believe he'd be the one making solid contact more often.
sorry homie...but you don't get the record for having the longest undefeated record, most championship fights, and most successful title defenses....and be overrated he has earned EVERY bit of his accomplishments :deal simply put, JCC was one of the best fighters that the sport of boxing has ever seen.
