HBO Nick Buoniconti

HBO Sports' latest documentary, "The Many Lives Of Nick Buoniconti," has an added layer of resonance because of the cable network's connection to the Pro Football Hall of Famer. In 1979, Buoniconti and Len Dawson began a run of more than two decades as co-hosts of HBO's "Inside The NFL." It was a show that helped HBO increase its credibility in the sports realm.

Along the way, the show also gave Cris Collinsworth one of his first breaks in sports broadcasting. Collinsworth remembers how Buoniconti gave him some tough love.

Check out this clip in which Collinsworth says he thought he might end up fighting Buoniconti. The film premieres February 12 at 10 p.m. ET/PT.
