Las Vegas, Nevada - Floyd Mayweather Sr., father and trainer for WBC/WBA welterweight and junior middleweight champion Floyd Mayweather Jr. (47-0, 26KOs), believes his son is going to dominate and stop Manny Pacquiao on May 2nd at the MGM Grand in Las Vegas.

A few years ago, Mayweather Sr. (and other Mayweather team members) accused Pacquiao of using performance enhancing drugs. Pacquiao filed a lawsuit for defamation and it was eventually settled, privately, between the two parties.

Despite the lawsuit, Mayweather Sr. is still question Pacquiao's run of dominating performances when he first moved up the welterweight division in 2008.

If you read between the lines, Mayweather Sr. appears to believe that Pacquiao was using something in the past, stopped taking it - and that's the reason for the Filipino superstar not scoring a knockout victory since 2009.

"Is any lawyers in here? That's what the hell I want to know. [Pacquiao] ain't gonna do sh*t because little Floyd is gonna crush his ass. Do you know why? All of that punching power that ya'll talking about that he got....forget about it, it's done. It's over. It's no more. Floyd is gonna tear his ass apart," Mayweather Sr. said.

If the fight would have happened five or six years ago, Mayweather Sr. admits that it could have played out differently - but again, if you read between the lines, he believes it would have been different because Pacquiao was allegedly using a performance enhancer.

"Yeah that fight could have been different. Do you know why? Because people sometimes do things that other people don't do. So it could have been different. But being that things are random right now, he's gonna get his ass torn out the frame," Mayweather Sr. said. 

"Aint nobody been knocked out in five damn years. Explain that to me. Five years aint nobody went to sleep, aint nobody went on the mats. What the hell is going on? Something aint right."
