Arce's performance was more of a case of a very good small fighter defying the odds and pulling off an upset, he was on a winning streak going into the fight, not so much Vazquez Jr being overrated, the guy still has less fights than Chavez Jr and yet he's already faced better opposition all around, only REAL name on Chavez' record is in his loss against Martinez (which apart from the final round was what I'd call a raping)
