Offense vs Defense

Shane Mosley and Floyd Mayweather, who finally meet in the ring May 1 in Las Vegas, are as different as night and day or salt and pepper. As you will witness when you watch Mayweather vs Mosley live stream this weekend.

Their welterweight mega-showdown (9 p.m. ET, HBO pay-per-view) at the MGM Grand Garden Arena promises to be a contrast of styles and personalities.

A look at a few points of difference between 38-year-old Mosley (46-5, 39 KOs) and 33-year-old Mayweather (40-0, 25 KOs).

Mosley is an offensive fighter, a skilled power puncher who comes to fight. He has been involved in several all-out brawls, most recently his welterweight title victory against Antonio Margarito, in which he pounded Margarito into submission in the ninth round.

He also brawled in his fights against Oscar De La Hoya and Fernando Vargas. Mosley's defensive shortcomings can leave him vulnerable to counterpunching, which is one of Mayweather's strengths.

Mayweather is skilled at avoiding getting hit. His only stoppage since 2006 was a devastating 10th-round knockout of Ricky Hatton in December 2007. His quickness is hard to match, though Mosley says Mayweather will meet his match on May 1.

Mayweather admits his fighting style is 180 degrees opposite of Mosley's.

"We're totally different," Mayweather said Thursday during a conference call with news reporters. "He's a fighter that always worries about landing one big shot. He worries about who's extremely strong. And I worry about being smart and winning.

"Shane maintains a low level with wide shots and not using a full jab. I use a full jab. When I shoot my shots, I look at my opponent, look where I'm punching. When Shane punches, a lot of times he closes his eyes. We're two totally different fighters."
