Mayweather could never win in a "fight" with Duran. He would have to take no chances at all. Mayweather would not be able to win in close against Duran so he would cautiously fight on the outside under the aggresion of Duran. So, Duran would be the dictating the pace of the fight while PBF would be pecking away at him andscoring points with meaningless punches. PBF would likely win a close decision en route to losing a lot o fans.............................................. ..................oh yeah and the other outcome is PBF gets batterered by the tougher, more aggressive and harer puncher Duran and gets stopped late trying to trade with the hands of stone.
