Marvin Hagler
Marvelous Marvin Hagler (that’s his legal name) was one of the most dominant middleweights in modern history. His reign as undisputed champion lasted for seven years, from 1980-1987, before he was narrowly, and controversially, defeated by Sugar Ray Leonard in a split decision.
Hagler is known for his granite chin, and he measured up well against other contemporary legends. Even with the loss to Leonard, he holds a decision victory over Roberto Duran and a knockout win over Tommy Hearns in The Ring’s 1985 Fight of the Year.
