He challenged Larry Holmes for the WBC heavyweight title in November 1982, losing a one-sided unanimous decision. Cobb took wins over notable heavyweights of his era such as Bernardo Mercado, Earnie Shavers, and Leon Spinks. He was ranked in the global top 10 heavyweight boxers by the Ring (in 1981 and 1982) and BoxRec (in 1982).
