UFC light heavyweight champ Jon Jones has clearly established himself as one of the finest fighters to ever set foot inside the Octagon. His record stands at 19-1 and the only blemish came as the result of a sketchy disqualification defeat rather than a legitimate loss. He’s dominated a number of Top 10 opponents along the way and only received one real run for his money courtesy of Alexander Gustafsson’s effort this past Saturday night at UFC 165. With a plethora of impressive performances to choose from it’s not easy to whittle things down to the five best but it’s definitely doable. (Photos by USA Today Sports Images)
