“... Both guys did what they did and the best one won. I only wish the best for Errol Spence... If I had coached him and been in the corner, I would be against him competing at welterweight at all. And I don't think he needs to fight at junior middleweight. I think he should have fought at middleweight or super middleweight. That's my opinion," Mayweather said.
Recall that Crawford defeated Spence by TKO in the ninth round.
