Who needs enemies when you can have a boxing press conference.

There was certainly no love lost between six-time world cham Floyd "Money" Mayweather and "Sugar" Shane Mosley, who exchanged blows at a New York City press conference to announce their May 1 fight at the MGM Grand Garden Arena in Las Vegas.

The two certainly didn't share any kind words for each other during one-on-one interviews with the media.

"No disrespect...[Mosley's] and HBO fighter," Mayweather said. "After that he's going right back to HBO. I'm a Pay-Per-View fighter and that's the difference."

Mayweather, as usual, played the me-against-the-world card in regards to his ability to draw big audiences for his fights and the ability of his team, including his uncle and trainer Roger Mayweather.

"I never get the credit and my team never gets the credit for me having such a smart plan," Mayweather said. "I’ve been dominating this sport for 14,15 years and not once has [Roger Mayweather] got trainer of the year. Not once has [advisor] Leonard Ellerbe got manager of the year. The sport of boxing is a crazy sport." 

Mayweather may have a point there. He's generated 5.5 million Pay-per-view in his last six fights, including a PPV record 2.5 million for his tilt with De La Hoya in 2007.  

His last fight against Juan Manuel Marquez generated 1.2 million PPV buys.   

As for Mosley, he's thankful to get a chance to get back on the big stage. Mosley last fought and defeated Antonio Margarito on January 30, 2009.

"After sitting on the shelf for a year, I got kind of frustrated, I’m like why am I’m not getting these fights," Mosley said. "I love to fight. I love to be in the gym. I’m always training."
