There are no real arguments nowadays from fans or experts that Jon Jones is the greatest MMA fighter of all time. Jones standing so far ahead of the rest in terms of the MMA GOAT conversation has led to many people comparing ‘Bones’ to fighters outside of MMA when discussing his greatness.UFC commentator and MMA expert, Jon Anik has argued that Jones’ legacy has already surpassed two of the greatest undefeated boxers of all time, Floyd Mayweather and Joe Calzaghe. While Jones technically is not undefeated due to a controversial disqualification loss being on his record from 2009, Anik believes that the reigning UFC heavyweight champion has been tested more than Mayweather and Calzaghe were throughout their careers.
