NEW YORK — Shane Mosley bopped around the Super Bowl media center last week, chatting with anyone who wanted to listen about his upcoming fight against Floyd Mayweather Jr. He seemed positively giddy as he stopped by radio row to talk about the serendipitous opportunity.

And after he departed sunny Miami for frigid New York, the smile still hadn't left his face.

"This is not going to be personal for me, this is going to be fun for me," he said Tuesday over lunch at the Hard Rock Cafe. "This is like when I fought Oscar (De La Hoya) the first time. People told me, 'Oh, you're going to be afraid. Are you scared?' No, no, this is what I want.

"It's not going to be personal, I'm not going to be upset," Mosley said. "I'm going to have fun. I'm going to have fun beating Mayweather."

Two of the best 147-pounders in the world will meet May 1 at the MGM Grand in Las Vegas, in what is easily the biggest fight in boxing that doesn't involve a Filipino fighter named Manny.

Mayweather (40-0, 25 KOs) is a five-division champion whose flamboyance has made him a crossover star, with interests as diverse as WWE's "Wrestlemania" and "Dancing With the Stars." He's been involved in some of the richest fights in boxing, but is still hounded by critics who claim he's never fought a true welterweight in their prime.

Mosley (46-5, 39 KOs) is a three-division champion who has pursued Mayweather since the late 1990s, when they were both in lighter divisions. He's faced just about every big name available, from De La Hoya to Antonio Margarito, but has dealt with his own critics after admitting to unknowingly using performance-enhancing drugs.

"It won't be the fight of my life, but I just want to make a point that I'm the best fighter," Mosley said. "There's not a welterweight out there who can beat me. I don't just want to talk about, I want to do it."
