Marquez looks sluggish at 144, Pac by KO simply because Pac is better with the added weight than Marquez is. At 135 (I think Pac can make it since he made 138 comfortably for the Hatton fight), I'd go with Pac by decision in yet another close fight.
At light welterweight and above, i'd have to go with Pacquiao by stoppage as much as i hate to say it.
He looked slow because of Floyd, Floyd defense and counterpunching skills made it difficult for JMM to do his stuff.
JMM should not fight manny NOW .manny waits for the BEST to fight each OTHER wear themselves out. then when they show sidns of slipping he WANTS to fight them for his country. then he says its PERSONAL...
Pac carries the weight MUCH better than JMM. Had Pac not come on the scene JMM would probably STILL be fighting at featherweight.
