...It's common sense. Morales lost handily to Raheem, he had been fighting since he was 16 years of age, had been through wars with Pacquiao, Barrera x2, In Jin Chi, Jesus Chavez, and Daniel Zaragoza. ...Morales was slipping by the time of his rubber match with Marco.
TBH, I think there was no intention of tarnishing Morales' win when that 2005 video (which was taken days after Pacquaio was beaten by Morales) was posted here in the forum. It only showed us that even during that time, 2005, Pacquaio has indicated his discomfort of having his blood taken days before the fight, as he thinks it has effect on him. And in the light of this whole random blood testing, it supports his reason of not agreeing to it unless it is mandated by the commissioning body.
