A fighter's career highs are almost always marked by major wins or achievements, but in the case of UFC light heavyweight contender Alexander Gustafsson, that may not be the case. His resume of wins is impressive, but two of his most notable losses might be his two best performances.
The first was an attempt to take the title from then-champion Jon Jones at UFC 165 in September of 2013. The Swede pushed Jones to the brink, but came up on the wrong end of a unanimous decision. Still, his ability to hurt and stifle Jones in the way he did was and remains unprecedented.
