Re: If JMM is such a "Warrior", why hasn't he called out Mayweather for a rematch?
Pacquiao and Marquez should fight each other a 5th time and then retire. The reason I feel they need a fifth, is because Pacquiao granted Marquez the third and fourth fights, when he already got the wins in the second and third. Marquez has to respect that, and grant Manny a rematch now he's the winner - These two are like Ali - Frazier, Holyfield-Bowe, Leonard-Hearns, Morales-Barrera, their legacies are intertwined, you can't mention one without bringing up the other.
On the topic of Mayweather-Marquez 2, let's be objective. Marquez is a great thinker in the ring, that night he had 12 rounds to effect any sort of effective strategy against Mayweather and came up with nothing. It wasn't the weight that inhibited him, it was the style and the level, Mayweather is simply too good for Marquez.
