82. Michael Spinks
Divisions: Light Heavyweight (175), Heavyweight (200+)
Years Active: 1977-1988
With his 14-1 record in world title fights, it is somewhat unfortunate that Michael Spinks is most famous among casual fans for the first round KO loss to Mike Tyson that led to Spinks’ retirement.
Spinks was a slim, 6’2″ puncher with a legendary right hand known as the “Spinks Jinx.” He held world titles for several years in the light heavyweight and heavyweight divisions. He skipped cruiserweight altogether—going from 174.5 lbs. to 199.75 lbs. in a three-month span before winning two consecutive title fights over legendary Larry Holmes.
He is the most accomplished of the famous Spinks family. His brother is former heavyweight champ Leon Spinks (who once beat Ali), and he’s the uncle of Cory Spinks, a present-day fighter and two-division champion in his own right.
