If there is any division in which there is no doubt about who the best fighter of the 2010’s was, it’s clearly light heavyweight. Jon Jones opened up the decade clearing out the legends from the previous decade, before turning the best this decade had to offer. Where the debate regarding 205 comes is in regards to what comes after him.
1. Jon Jones: A better debate for Jones is whether he’s the greatest fighter of all time rather than if he’s the top light heavyweight of the 2010s. The man didn’t lose a single fight during the decade, generally fighting the best competition that could be thrown at him once he claimed the belt, the lone exception being Chael Sonnen.
