FILE – In this April 24, 2012, file photo, NFL and baseball great Bo Jackson prepares for his 300-mile bike ride to benefit tornado victims in Alabama in Henager, Ala. "You Don’t Know Bo," a documentary about Jackson, will premiere Saturday, Dec. 8, on ESPN after this year’s Heisman ceremony. Jackson won the 1985 Heisman Trophy. The title, a play on Nike’s famous "Bo Knows" commercials, was partly inspired by a conversation director Mike Bonfiglio had with his two teenage cousins, both big sports fans. They didn’t know Bo.
