Mayweather VS Mosley Match: Who R U Picking – - Is like a time bomb that tik toks and ready to explode on the day of event this Saturday evening.

The three 147-pounder and their stats were: Manny Pacquiao (51-3-2, 38 knockouts), Floyd Mayweather Jr. (40-0, 25 KOs), “Sugar” Shane Mosley (46-5, 39 KOs) and, on the cusp, Andre Berto (26-0, 20 KOs).

On the other hand, the experience of Mr. Mayweather within his 40 bouts, and he is a six-time world champion, undefeated and relatively untested. The only opponents to seriously challenge the Grand Rapids, Mich., native were Oscar De La Hoya and, to a lesser extent, José Luis Castillo. While some of the all-time greats lost fights and absorbed lessons from their setbacks, Mr. Mayweather’s unblemished record is at the core of his sense of identity.

Meanwhile, contrasting Mr. Mosley, his boxing is now mostly about a legacy. The five-time world champion emphasizes: “I’m fighting for my place in history. To be the best.” Mr. Mosley’s trainer, Nazim Richardson, was more specific. A few months ago he told me: “Shane wants to earn his ‘sugar’—his place with the other sugars, Sugar Ray Robinson and Sugar Ray Leonard.”

However, for all his shenanigans out there, Mr. Mayweather a33-year-old is as disciplined as a monk when it comes to his art. He is always superbly conditioned. Emanuel Steward, the boxing commentator and legendary trainer, noted: “Floyd is not fooling around for this one. He is really focused. Honestly, I think this is the first time that he is in there with someone whom he thinks he could actually lose to.” And with good reason; at 5 feet 9 inches, Mr. Mosley is a big, powerful welterweight who loves to exchange punches and who, even at the advanced boxing age of 38, is only a few nanoseconds slower than the 5-foot-8-inch Mr. Mayweather.
