DLH, Canelo, Paquiao, Cotto
no they wouldnt be undefeated like mayweather
they might win some of those but all 4, i dont think so
even a judah, neither has fought a welter as good as him and that is not even like top 5 wins for mayweather
DeMarcus Corley is not a top 10 win for Mayweather but I still think they would have trouble beating him.
TC also never fought someone with the heart and intensity of Gatti.

I am not sure.Of course Spence was always a welterweight while Mayweather was a 21 year old champion at 130 so Spence could not fight any of the guys Mayweather fought below 147. Crawford fought at lightweight so he would have to fight Castillo. They both may have suffered a loss fighting all the guys Mayweather beat or in Spence's case all the guys 147 or heavier.
