Summerall's stature as pro football's premier television broadcaster was a result of two things: first, his ability to play the "straight man" alongside John Madden's lively, verbose persona; second, his economical delivery that magnified the drama of a moment while allowing the pictures and his baritone-like voice to tell the story. His style was closely modeled on that of his predecessor as CBS' main NFL announcer, Ray Scott, also known for his minimalist style. One of Summerall's most memorable on-air calls was his account of Marcus Allen's electrifying touchdown run in Super Bowl XVIII.
