San Juan Boxing Gym just doing the simple basics. A few months later, Clinite made arrangements for Randall to be sent to Joe Frazier's gym in Philadelphia. Boxing career After nine straight wins as a kickboxer, Cobb lost his first two amateur bouts. In his professional-boxing debut on January 19, 1977, in El Paso, he knocked out Pedro Vega. He went on to win 13 straight fights by 1979, all by knockout. Cobb was a fighter who had hitting power, as shown by his eighth-round knockout victory over Earnie Shavers in 1980. He lost his two following bouts to Ken Norton and Michael Dokes, respectively, but soon bounced back to earn a shot at Larry Holmes' WBC World Heavyweight Championship. On November 26, 1982, at Houston's Astrodome, Cobb was defeated in a unanimous decision by Holmes, who won all 15 rounds on two of three scorecards.

When prodded further regarding Cosell's remarks, Cobb observed, "Hey, if it gets him to stop broadcasting NFL games, I'll go play football for a week, too!"

Between late 1984 and 1985, he lost four straight fights, the last of which was a knockout at the hands of Dee Collier, the only time he was ever KO'd. After a two-year hiatus, he made a return to the ring and went on a 20-fight undefeated streak against lightly regarded opponents (including a win over past-his-prime former champ Leon Spinks in 1988) before retiring again rather suddenly in 1993.
