Pacquiao was 145 in the ring for the second Marquez fight.
Pacquiao is a much better fighter when he isn't cutting so much weight. When he's drained he gets hurt, or even KO'd (Singsurat fight).
It's been the norm for boxing for God knows how long for boxers to fight at a weight division waaay below their natural weight. Pacman showed them the way that it isn't necessary to cut weight just to gain an advantage, thanks to Oscar!
