If Mayweather wins by stoppage then I think it speaks volumes. But I seriously think he would be going tooth and nail to get a stoppage against JMM. But for the sake of argument, if PBF does stop JMM I am certain people will belittle it with the overstated size advantage. I guess JMM is too little for PBF but Pac isn't. Go figure. But I'm sure neither guy is an easy night for PBF, who is a miniature welterweight.
