Martinez already bitched out. not so tough when a bigger guy calls him out. he will whoop Chavez Jrs ass though.
No, he beat the unified champion, destroyed Williams, beat good fighters in Dziniruk, Barker, and Macklin. Martinez is a great fighter regardless of what happens against overweight steroid cheat JCC Jr.
Martinez could beat anyone at 160 by late round stoppage, then eat a sandwich, drink a bottle of red wine, go twelve rounds with Andre Ward, knock him down twice, and get robbed by SD... Just kidding!
