Mayweather Sr. accused MannyPacquiao of using steroids even before the cotto fight. MP kept quiet so he could concentrate on the upcoming fight.

now that the bout with FMjr is in the works, the dirty talk didnt stop from the mayweather camp, MP's super pissed, its a demolition job! all the hard work sacrifice etc that brought him to the top is being put into question without any proof/evidence. MSr. (and paulie) sowed the seeds of doubt.

had the drugtesting issue been demanded/requested by the governing body (NSAC) then MP would have agreed. but coming from the mayweathers & gbp, no way! MP knows that the mayweathers' into mindgames so he stubbornly stood his ground. they wont own him!
