My thoughts concerning the upcoming Mayweather vs Pacman2 is to discard the news because Mayweather and his camp have not to say anything about it and they never want to accept the offer. Besides, if Mayweather chooses not to fight Pacman then what will make him change his mind now?
Looks like the invitation was coming from Mayweather's side per OP's post, therefore Mayweather and his camp knows about it. The only question now is, is this news reliable enough?
what i dont like with mayweather is his priority is always money. if he feels he's not getting the advantage with the purse money, he will not do it. so it is really up to him if this May-PAc 2 will happen. but the enthusiasm i believe is not the same as their first match. a lot of people felt cheated the way he performed inside the ring.
but lets see if this will end up talks only or their promoters will make this happen...
