Mayweather or Crawford: Spence named best boxer

Former world champion Errol Spence has explained why he thinks Floyd Mayweather is a better boxer than Terence Crawford.

"It's a whole different level. Floyd is a special fighter. I'm sure he's superior to Terence Crawford. I don't know how much he is the best fighter of all time, but maybe he's close to it," Spence said in an interview with FightHype.

Recall, last July Spence and Terence Crawford met in the ring in a battle for the title of absolute world champion in the welterweight division, and then Terence declassified Errol, knocking him out in the ninth round.
