If Pacquiao & Mayweather do win their respective matches, don't we want them to meet and settle once & for all who really is the P4P king? And we know that neither of them would give in to a lesser purse. It should either be a 50/50 or a 55/45, 60/40 with the remaining amount going to the winner. Why should we insist that one fighter gets more? We won't be getting a cut from their share. So what benefit would we get from favoring a higher split for a certain boxer?
