Joe Calzaghe. The only controversy is that Bernard Hopkins and Robin Reid both got SD's when it was clear to the public and media that Calzaghe had won.
Some members of the media, and the fans (even Calzaghe fans on this board), had Calzaghe losing. I suppose you can argue the quick stoppage against Mitchell.
I think that all of Vitali´s fights were clear. He either won convincingly or got injured or cut to the point of a fair stoppage or sensible surrender. Still, some people feel the Lewis fight should not have been stopped, so you could call that "controversial". Wlad´s fight against Brewster was controversial though, as it is unknown whether there was some foul play involved.
I woudnt say mitchell weas a quick stoppage. he had been floored and was falling around the ring like a drunk when he was stopped. However 2 SD's and fights like Manafraido discount JC from having no controversial fights. I cant recall Hamed ever having a controversial one. When he won he won, when he lost he lost. Same could be said of Herbie Hide.
True not to mention the "Long count" against Buster Douglas. Even when you get KTFO you can argue :good
Chavez when he faced Taylor for the first time. It seemed everyone was on the same page with that fight.
Paul Williams! When we whipped Margarito's ass there was no controversy, although it shouldn't have nearly been that close! And despite the fact that Margarito whinin ass tried to create a controversy!
Many people thought that Douglas got a long count. Norris also was ruled a NC along with Golota when they could of been wins. Unless you were kidding :huh
