Rebound (1996)

From Hoopedia

Don Cheadle, James Earl Jones, Michael Beach, Clarence Williams III, Eriq La Salle, Forest Whitaker. True story of the legendary Earl "The Goat" Manigault, Harlem playground star who lost his chance at NBA stardom because of drugs. (He finally got a tryout in 1971 with the ABA Utah Stars but was released). He sobered up and ran an Inner City drug program until he died of heart failure in 1998. Kareem Abdul-Jabbar, who once called the slam-dunking Manigault the best player he ever saw, appears briefly at the beginning of the film.

The film has been criticized for its portrayal of Holcombe Rucker, who served as a mentor to Manigault. Rucker is made out to be a paunchy janitor, when in fact he finished college in three years while working as a playground director.
