Arguably the greatest fighter ever, Jones has put together a resume unlikely anyone else in UFC history. He’s by far the youngest member of the 20-win UFC club, but it will forever remain a mystery how much further ahead “Bones” would be if personal issues didn’t sideline him from competition for significant portions of time.
