2. Georges St. Pierre vs. BJ Penn

UFC 58

This was the moment for French-Canadian welterweight St. Pierre. He had attempted to take down Hall of Famer Matt Hughes at UFC 50 and failed, but had since proven he was among the best in the sport. It all came together for him at UFC 58 when he beat former champ BJ Penn in a split decision to become the #1 contender, all set for his rematch with Hughes. It didn't come right away, due to a St. Pierre injury, but eventually he got his shot at Hughes and handled him easily.
