Is Sugar Shane Mosley Draining weight to fight Manny Pacquiao and why does Manny always need to fight at a?

Catchweight. If Manny was a real champion moving up in weight classes he wouldn't need fighters to drain weight such as ''COTTO'' , DE LA HOYA , MARGARITO''. Fight them at there real weight class and stop looking for easy hand outs. What no one realizes is that when you drain 10-15 pounds your very weak and hurting your body. This is all done for Manny to win because people like to see him in the ring because of his speed and bad defense. He is truly a overrated fighter who LOST 3 TIMES and wants fighters draning weight. Don't move up in class if you can't handle bigger fighters. And Mayweather will beat Manny Pacquiao because he is just a better fighter who rarely if never fought other boxers at catchweight.
