In a lengthy new interview with Fighthype.com, Floyd "Money" Mayweather claims that a superfight between he and Manny Pacquiao was scuppered because of the Pac-man's refusal to go along with unlimited, random drug-testing.
He also strongly implies that Pacquiao's past success has in part been the result of performance-enhancing substances.
"The Mayweather-Pacquiao fight didn't get made because Manny Pacquiao said he wanted two weeks of non-testing," Mayweather states in the interview.
"The last two weeks leading up until the fight, he didn't want to take the tests, so that's why the fight didn't happen. Everything they asked of me, I agreed and what I asked of them, they didn't agree," he continues.
"When Manny gave blood before the first Morales fight," Mayweather says, "he lost. He didn't give blood for the next two fights and he knocked Morales out with ease. A lot of times, people don't realize, giving blood doesn't make you weak. Not being able to juice because you have to give blood makes you weak. That's what a lot of people don't realize and don't know."
Mayweather also notes that other top fighters "have been known to dibble and dabble in enhancement products."
"I just think that it's right that all fighters should take a test just to show the world our sport is clean," says Mayweather.
"We got some future Hall of Famers that's, I'm not saying it's steroids, but people seem to forget about Fernando Vargas, Roy Jones, James Toney and Shane Mosley [all of whom have been linked to PED use]. Those are just a few fighters, and I truly believe all of them are future Hall of Famers."
"Money" also makes it clear that he feels under-appreciated in the boxing world, especially in comparison with the adulation Manny Pacquiao receives.
"Before I fight an opponent, they build them up. They say that this is going to be Floyd Mayweather's toughest fight and possibly his first loss," he contends.
"As soon as I beat them and make them look like an ordinary club fighter, that's when they say, "this guy is washed up, he's too old, he's too slow," and then they discredit me saying I'm not a great fighter."
