Mayweather is all about money and if he wants a rematch that's all its about (money), the entertainment is gone and that's what's boring on every match of Mayweather.
Every fight that Mayweather involves is boring one as he is the best defensive boxer the world as ever seen but the most compelling thing is that all his fights are grossing record breaking PPV and made billions in his fight career alone and so is the reason even Conor McGregor wanted to box Mayweather for the amount of money they could make together and they made that possible.If Pacquiao surely wants a rematch a good strategy to break that defensive style of Floyd is totally a must and a knockout as well. I'll always bet for Pacquiao not as just my countrymen but as the love of this man on this sport.
If Manny Pacquiao wants a rematch, Floyd Mayweather has to accept that fight and it is as simple as that 
. Winning the fight is another factor altogether but as a fight fan i would like to see a healthy Manny v Mayweather one last time.
