The Haugen fight is one of my favorites. He was out of shape and undersized against Vasquez, but that's a good one to watch as well. Beating a damn good 154 pound champ (who was better than guys like Cotto and Canelo imo) whilst faded and undersized. Check out the Brazier fight in addition to all the ones listed by Vidic.
I liked his fight with Mayweather, both fights Mcgirt (who was a very good fighter himself but never the same after his first loss to him) De La Hoya and Chavez His style was dope!!!!!!!!!!!!!!!!!!!!!!!!!!!! A born show man! Slick boxing at it's finest....
