Going into the 1981 NFL season, CBS Sports executives decided that John Madden, who had joined the network in 1979 and had worked with Frank Glieber and Gary Bender (Pat Summerall and Madden were first teamed on a November 25, 1979 broadcast of a Minnesota Vikings–Tampa Bay Buccaneers game) in his first two years, was going to be their star NFL color commentator. But they had trouble figuring out who was going to be his play-by-play partner. At the time CBS had reshuffled their #1 team lineup as Summerall's longtime broadcast partner Tom Brookshier was moved into a play-by-play role, and it was not immediately clear if Summerall was going to keep his position or if the network was going to promote #2 play-by-play man Vin Scully, whose contract was nearing expiration, to take over. CBS elected to give both Summerall and Scully chances to work with Madden. Scully worked with Madden for four games in September while Summerall was busy covering the U.S. Open tennis tournament for CBS. Summerall then worked with Madden for four October games as Scully called Major League Baseball's National League Championship Series and World Series for the Los Angeles Dodgers Radio Network and CBS Radio respectively. After the eighth week of the NFL season, CBS Sports executives decided that the laconic, baritone-voiced Summerall's style was more in tuned with the lively, verbose Madden than the elegant, poetic Scully. As a consolation prize, CBS Sports gave Scully the ""B"" team assignment and the right to call the NFC Championship Game on CBS Television with Hank Stram. Meanwhile, Pat Summerall called that game on CBS Radio with Jack Buck while John Madden prepared to do the Super Bowl with Summerall in Pontiac, Michigan. Vin Scully reportedly was not happy about the demotion as well as (in his eyes) having his intelligence be insulted (at least, according to CBS Sports producer Terry O'Neil in the book The Game Behind the Game). As a result, Scully bolted to NBC (where he started a memorable seven-year run as their lead Major League Baseball announcer) as soon as his contract with CBS was up.
