UFC CEO Dana White called the organization's current heavyweight champion Jon Jones the greatest fighter in history.
"He never lost and destroyed everyone in the flyweight division, which at the time was the toughest division in the promotion and in the sport in general. Then he moved up to heavyweight and started winning there. That's Jon Jones. There can't be any arguments. No one can argue who the greatest fighter of all time is. It's absolutely Jon Jones. He's never lost. Another thing to consider is the length of performances. You can hate it, but Jon Jones is the greatest fighter of all time," White was quoted as saying by YouTube channel Lex Fridman.
