By Tim Fletcher: Floyd Mayweather Jr. is really high on undefeated welterweight contender Errol Spence Jr. (19-0, 16 KOs), and he sees the 26-year-old fighter making the most impact in the welterweight division now that he’s retired from the sport.
Mayweather says he’s going to be signing the young Spence, and he thinks he’s going to be a star.
