Why does Pacquiao usually scores a knockdown on his opponents?

[hitmanhatton]

Does use of 'roids count as 'other'?

Many people were speculating on that but Pacquiao had undergone drug testing on every fight and passed those tests. Maybe it's time for Manny to submit himself for thorough investigation.

tests tend to mean very little these days....

shane mosley - never failed a test
barry bonds - never failed a test

and alot of people are saying "he is just an extrodinary athlete he doesnt need any help" im pretty sure these would have been the same responses from RJJ fans before he got caught
