Where did the Radio nickname come from?
From wiki:

Radio, released October 2003, is a film directed by Mike Tollin that is based on the true story of T.L. Hanna High School football coach Harold Jones (Ed Harris) and a mentally-challenged young man James Robert Kennedy, nicknamed "Radio" (Cuba Gooding, Jr.). Also starring Debra Winger, and Alfre Woodard, it was based on the December 16, 1996 Sports Illustrated article "Someone to Lean On" by Gary Smith about James R. Kennedy and Harold Jones.
