1. Tim Sylvia vs. Andrei Arlovski 3 (UFC 61)
UFC 61: Bitter Rivals featured the rubber match between two heavy-handed heavyweights who had been trading the title belt back and forth. When towering boxer Tim "The Maniac" Sylvia first squared off with "The Pitbull", Andrei Arlovski dropped him with an overhand right and subbed him with an achilles lock inside the first minute. The rematch swung the other way, with Sylvia surviving a knockdown from another overhand right only to get back up and pop Arlovski on his cotton candy chin, finishing the champ by TKO in the first round. After his victory, Sylvia requested a third and deciding fight to determine a clear winner of the rivalry. After two straight first frame finishes chances were good that we'd see another exciting fight. But at UFC 61, those "bitter rivals" looked more like repellant magnets, avoiding each other like they were allergic to human contact. It was everything that isn't great about mixed martial arts, when two championship-caliber fighters with high stakes are too afraid to lose to enage, and the fans were furious. Sylvia may have emerged victorious on the score cards, but neither man really won after such embarrassing performances, and the bout still stands today as the example of what not to do if you want to make it to the top of sport.
