In the past, WBC/WBA welterweight and junior middleweight champion Floyd Mayweather Jr. (47-0, 26KOs) was the master of the pre-fight verbal banter. As the days count down to the biggest fight of his career, Mayweather has been noticeably quiet.

On May 2nd at the MGM Grand in Las Vegas, Mayweather will take on WBO welterweight champion Manny Pacquiao in a mega-fight unification on pay-per-view.

Over the last few weeks, several members of Pacquiao's team have taken shots at Mayweather - including stories of sparring partners busting up the pound-for-pound king in camp. Through it all, Mayweather has stayed quiet and offered no verbal retaliation.

"It was a lot to make this fight happen. In the past, everyone was saying it was Floyd (who was blocking the Pacquiao fight). And my thing was this, if I didn't have nothing good to say, don't say anything at all," Mayweather told Mlive.com.

"That's no different than in the past, like I look back at certain things, 'Damn why did I do that?' Like, you're older, you're wiser, and my focus should only be the fighters that I'm facing. Those are the only people I should have a problem with or a beef with, not anyone else."
