De La Hoya: Pacquiao makes fighters lose on the scales 1st

[arcanum26]

Yup and it's a simple answer.

YES OF COURSE IT AFFECTS HIS OPPONANTS. WHY ELSE WOULD HE MAKE THOSE DEMANDS?

To even the playing field? If his opponents (cotto/margarito) thought they had a good chance of winning against manny at their respective catchweight fights then sign the contract, why would you blame it all on manny? It affects his opponents but you can't quantify it in absolute terms the way you can't say how much an advantage they would have against manny come fight night after they rehydrate themselves.
