where would he rank all time? thats saying he beats both mayweather and pacquiao. or one of the two, whatever the case is. where would he rank all time? remember, there was a time when he was p4p number 1. a time when he knocked out every lightweight he ever faced and a time when he came up and dethroned a then, in his prime, oscar de la hoya.
Hypothetically if Mosley beats Manny or Floyd, he will definitely throw himself into the ATG list. No one has gone back up to P4P, that's a hard title to get twice.
He is already up there on the ATG Welterweight list. He would move into the top 5 welterweights if he could pull this off. Shane has the rare double threat skills, and a heart!
He would jump up several more notches on an ATG list but mostly because it would take a few very significant wins for him to regain the No. 1 P4P list. It's not about that title, it's about what he would have to do to get it.
