8. Marvin Hagler; 62 W, 3 L, 2 D, 52 KO
Born in Newark, New Jersey, May 23, 1954. Because he felt that he did not receive enough credit for his accomplishments, Hagler legally changed his name to Marvelous Marvin Hagler. He is widely regarded as one of the greatest middleweights of all time. Later in life he moved to Italy, where he made low budget movies.
He reigned as the undisputed middleweight champion from 1980 to 1987, making twelve defenses of that title, and today holds the highest knockout percentage of all undisputed middleweight champions.
7. Archie Moore; 181 W, 24 L, 9 D, 1 NC, 145 KO
December 13, 1913 – December 9, 1998. If only for his impressive and superhuman career record, the Old mongoose could well have been the greatest. His fighting career spanned all four decades and has knocked out more fighters than any of the other great fighters in this top 10 list.
Moore holds the record for the most career knockouts (131) in boxing history, the longest reigning World Light Heavyweight Champion of all time (December 1952 – May 1962). He trained boxers such as Muhammad Ali, George Foreman and James Tillis.
