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.
That is his strategy, we can't blame him for that.
A lot of Filipinos hate that stance, that way of boxing since as a Filipino, I know that my countrymen wants a fight that, as someone said it here in the thread, a fight with those slugfest and see who really is the stronger boxer. Mayweather use his advantage, a tactic that people don't like but is so effective that makes him undefeated for a long time.
