By Eric Thomas: Trainer and former fighter Roger Mayweather thinks that Antonio Margarito is going to be weakened by having to melt down to fight Manny Pacquiao at the 150 pound catch weight for their November 13th fight at the Cowboys Stadium, in Arlington, Texas.

In an interview at Fighthype.com, Mayweather says “Margarito gotta make 150. He gonna kill himself to make that 150. Motherf***** tell him to fight at 150…He [Pacquiao] made them [De La Hoya, Hatton and Cotto] other mother******s shrink down just like he’s going to do to Margarito. It’s the same thing. He gonna make him drop that mother****** weight. You want to get this money, you better drop that mother****** weight.”

Mayweather thinks that Pacquiao needs catch weights to beat the bigger quality fighters that he’s been fighting lately. Pacquiao used a catch weight for his fight with Miguel Cotto to fight him for his WBO weltewerweight title. There wasn’t a catch weight for the De La Hoya bout, but the fight took place at 147, and De La Hoya had to come down from 154 to make that weight.

Margarito will have to melt down an additional four pounds to fight Pacquiao at the catch weight of 150 for the vacant World Boxing Council junior middleweight title. This rubs some people the wrong way because Pacquiao is fighting for another title at a catch weight instead of at the full weight for the class.

If Margarito insisted that the fight take place at the full weight, some boxing fans think he would he would then be replaced with another fighter that was more agreeable to what Pacquiao wanted in terms of the catch weight.

Margarito, who lost his boxing license after a plaster like material was found in his hand wraps a year ago, was hardly in the position to give Pacquiao any grief about his request for a catch weight. Margarito is just happy to get the fight no matter how much weight he would have to melt off to satisfy Pacquiao and his management team.
