Mayweather has said multiple times that he has lost his love for the sport. It's all business now. As I said before, the Pac fight was the huge fight everybody was waiting for. Now that it's over, I'm sure that he doesn't have the motivation to fight another tough fighter which is alright. I guess the argument is really should he just retire or fight someone like berto. If he wants to honor his six fight contract then who cares. Let him fight whoever.
