Ezzard Charles vs. Lee Oma - World Heavyweight Title - 1951-01-12 - Extended Highlights

Immediately following the fight, a bitter Cincinnati Cobra was irritated because of the boos and catcalls yelled at him after the fight, and because he felt he was not getting the credit that he deserved, even after a convincing win over Joe Louis. In truth, Ezzard was not getting the credit he deserved, primarily because he was fighting in the shadow of the great Joe Louis. "I'll keep on fighting and I'll keep on winning and then maybe the people will give me full recognition as champion. Maybe I'll show them more next time" Ezzard said.
