When was the last time Manny Pacquiao weighed in heavier than his opponent?

Probably never but let me get this straight, you don't think Manny fighting bigger opponents regardless of the BS pre-fight conditions is a bad thing? You will have a hard time convincing me of catch weight drain if it is less than 15 lbs over a 3 month minimum prior fight date informing. These are athletes who should be in training 24/7 365 so i am not much for the BS conditions(excuses for losing) to a smaller opponent.
