Does the fight against Pacquiao at 144 not give Marquez a chance to...?

I completely agree with your post and I've said it myself...it doesn't matter what weight they fight at, hell, they could fight at 150lbs, because essentially, they'll be the same size come fight night! Pacquiao might have a 2-3 lbs weight advantage...and become a full pledged welterweight like some people are saying...he's simply not dehydrating himself come fight night. Marquez should weigh in at whatever weight he feels comfortable and come into the fight at whatever weight he feels uncomfortable because essentially, they'll be the same size, give or take a couple pounds. Marquez made the mistake against Money that he tried to bulk up to get to the weight limit. With Pacquiao, he doesn't have to do that because Pac won't have as big a size advantage that Mayweather did so Marquez can come in at his "ideal" weight. Marquez's trainer sees your point too!
