On January 22, 1973, George Foreman took on the Undisputed Heavyweight Champion of the World, Joe Frazier, the fight would be dubbed "The Sundown Showdown" as it was fought in Kingston, Jamaica. Foreman, an Olympic gold medalist in 1968 stood 6' 3" and was a massive human being with great talent. His record was 37-0 coming into the title fight with 34 of those wins coming by knockout. "Smokin Joe" Frazier had won Olympic Gold in 1964 and had an impressive victory against Muhammad Ali in 1971. Frazier came into the match as a 3 to 1 favorite with a 29-0 record, the 24 year old kid nicknamed "Big George" would surprise him and the world.
Foreman would go onto defend the title successfully several times before meeting Ali in the famous "Rumble in the Jungle" in 1974. Ali got the best of George in that one and took the belt. Foreman, 20 years after losing the title to Ali, regained the the belt after beating Michael Moorer in 1994. Foreman's career was a great one that I believe was defined by "Down goes Frazier!!! Down goes Frazier!!! Down goes Frazier!!!"
