Bowl the next. Dorsett won both championships in the same building; Pitt clinched the 1976 national championship by defeating the Georgia Bulldogs in the Sugar Bowl on January 1, 1977. Dallas was the only NFC team to win the Super Bowl in the 1970s (although both Baltimore and Pittsburgh were pre-merger NFL teams). Both Cowboy victories in the decade came in New Orleans against teams making their first Super Bowl appearance. This was the first Super Bowl between two teams who had met in regular season play. The Cowboys defeated the Broncos 14–6 on the final Sunday of the regular season at Texas Stadium. Both teams' starters saw limited action in that contest, since both squads had already clinched their respective division championships and home-field advantage throughout the playoffs. Denver was 12–1 and Dallas 11–2 prior to the Dec 18 matchup. It was the first of only two times that two teams have played each other in the Super Bowl after playing on the final weekend of the regular season (the New York Giants and New England Patriots played in the final week of the 2007 regular season and met again in Super Bowl XLII). Under NFL scheduling rules put in place by Commissioner Roger Goodell prior to the 2010 season, the Super Bowl participants will no longer be able to play each other on the final weekend of the regular season, since all games on the final weekend now match division opponents. This was the first Super Bowl to feature arrow markers every ten yards, beginning at the 10 yard line, to indicate the direction of the nearest goal line, which were first used at Kansas City's Arrowhead Stadium in 1973. They became mandatory league-wide the following season in 1978. Broadcasting The game, the first Super Bowl to be played in prime time, was broadcast in the United States by CBS with play-by-play announcer Pat Summerall and color commentator Tom Brookshier. The game kicked off at 5:17 p.m. Central Standard Time. Hosting the coverage was The NFL Today hosts Brent Musburger; Irv Cross; Phyllis George (in the last game of her first stint on The NFL Today before leaving to host the short-lived People the following season). Also contributing were Hank Stram (who had recently been fired by the New Orleans Saints); Jimmy "The Greek" Snyder; Sonny Jurgensen (working on CBS Radio coverage); Gary Bender; Paul Hornung; Nick Buoniconti
