Manny Pacquiao vs. Antonio Margarito: Margarito Will Be Pac Man's Biggest Test

Manny Pacquiao has pummeled Miguel Cotto, devastated Ricky Hatton and absolutely punished Joshua Clottey into submission—but none of them are Antonio Margarito. Margarito is a fighter with nothing to lose, and boxers like that are the most dangerous to champions.

Think back to "Iron" Mike Tyson's fight against James Douglas. Many considered Tyson to be the best boxer in the sport at that time, but Douglas with four losses on his record accepted the underdog role and shocked the world with a stunning knockout victory.

Margarito is in the same position. Pacquiao is considered to be the best boxer pound for pound, and in a recent interview he said that he was the greatest boxer of all time.

Sure, Pacquiao is the current WBO Welterweight Champion and he's won nine world titles in seven different weight classes, but no fighter can proclaim they are the greatest of all time before they have finished their career.

If the movie, Rocky, taught us anything, fight fans, it's that big ego's don't match up well against determined underdogs.

Many fans, don't expect Margarito to do much against Pacquiao, except get knocked out; however what those fans fail to realize is that the only support Margarito needs is confidence in himself, which he doesn't lack the slightest bit.

In fact, in a recent sponsorship deal with clothing brand Affliction, Margarito announced that if he loses the fight, the Los Angeles based urban-ware company wouldn't have to pay him at all for wearing their gear the night of the fight.

Margarito must know something that we don't if he's willing to risk advertising money, in what will undoubtedly be the biggest fight of his life. Pacquiao is a big favorite, but don't be surprised if the "Tijuana Tornado" gives him a run for his money.
