Despite the controversies, two living legends of the sport have agreed to box each other for the fourth time.  

On December 8, 2012, Manny Pacquiao and Juan Manual Marquez will square off, probably fight 12 hard rounds, and have boxing fans scratching their heads.

Great rivalries have been such a huge part of boxing.  Win or lose (normally a bit of both), a great rivalry captures fans imaginations and embeds boxers into fight fans memories.

Joe Frazier and Mohammed Ali fought three times.  Ali won twice.

The ‘Thrilla in Manila’ was the third and final time the heavyweight legends met.

Dr. Ferdie Pacheco said, “Round 14 is the closest I’ve seen to somebody killing somebody.  Ali was very close to killing him.  Very close.  That’s what gets people killed in boxing.  When the fight becomes more important than life and death.’

Jake LaMotta and Sugar Ray Robinson fought five times.  Robinson won four, LaMotta one.  All were won by decision.

LaMotta won their second fight, and their third meeting was only three weeks after the second. 

Marco Antonio Barrera and Erik Morales fought three times.  First in 2000, then in 2002 and 2004.

Barrera won the final two contests.  The first and the third were named Fight Of The Year by Ring Magazine.
