Super Bowl VI

Super Bowl VI was an American football game between the National Football Conference (NFC) champion Dallas Cowboys and the American Football Conference (AFC) champion Miami Dolphins to decide the National Football League (NFL) champion for the 1971 season. The Cowboys defeated the Dolphins by the score of 24–3, to win their first Super Bowl, which was the first professional sports championship ever won by a Texas-based team. The game was played on January 16, 1972, at Tulane Stadium in New Orleans, Louisiana, the second time the Super Bowl was played in that city. Despite the southerly location, it was unseasonably cold at the time, with the kickoff air temperature of 39 °F (4 °C) making this the coldest Super Bowl played.

Dallas, in its second Super Bowl appearance, entered the game with a reputation of not being able to win big playoff games such as Super Bowl V and the 1966 and 1967 NFL Championship Games prior to the 1970 AFL–NFL merger. They posted an 11–3 record during the 1971 regular season before defeating the Minnesota Vikings and the San Francisco 49ers in the playoffs. The Dolphins were making their first Super Bowl appearance after building a 10–3–1 regular season record, including eight consecutive wins, and posting postseason victories over the Kansas City Chiefs and the Baltimore Colts.

The Cowboys dominated Super Bowl VI, setting Super Bowl records for the most rushing yards (252), the most first downs (23), and the fewest points allowed (3). They were also the first NFL or NFC team to win the Super Bowl since the Green Bay Packers in Super Bowl II. For the next 47 years, they would be the only team to prevent their opponent from scoring a touchdown in the Super Bowl, a feat matched by the 2018 New England Patriots in Super Bowl LIII and again by the 2020 Tampa Bay Buccaneers in Super Bowl LV. The game was close in the first half, with the Cowboys only leading 10–3 at halftime. But Dallas opened the third quarter with a 71-yard, 8-play touchdown drive, and then Dallas linebacker Chuck Howley's 41-yard interception return in the fourth quarter set up another score. This was the first Super Bowl where the winning team outscored the losing team in all four quarters. Cowboys quarterback Roger Staubach, who completed 12 out of 18 passes for 119 yards, threw 2 touchdown passes, and rushed 5 times for 18 yards, was named the Super Bowl's Most Valuable Player.

This was the last Super Bowl to be blacked out in the TV market in which the game was played. Under the NFL's unconditional blackout rules at the time, the Super Bowl could not be broadcast locally even if the local team did not advance to the Super Bowl, and it was a sellout. The following year, the league changed their rules to allow games to be broadcast in the local market if sold out 72 hours in advance. It was the last Super Bowl played with the hashmarks (also called the inbound lines) set at 40 feet apart (20 yards from the sidelines), and the last NFL game overall; the next season, they were brought in to 181⁄2 feet, the width of the goalposts, where they remain.

The NFL awarded Super Bowl VI to New Orleans on March 23, 1971, at the owners meetings held in Palm Beach, Florida. Six cities submitted bids: Miami, Dallas, Jacksonville, New Orleans, Los Angeles, and Houston. It took fourteen ballots to finally select a winner. Miami and Dallas emerged as the heavy favorites. After thirteen deadlocked votes, support for both Dallas and Miami eroded after owners including Al Davis and Billy Sullivan noted that the Cowboys and Dolphins both were both favorites to reach the Super Bowl. They argued against a team having a potential competitive advantage of a home game for the Super Bowl. Owners compromised on the 14th vote and selected New Orleans. City representatives, namely those from Miami, argued that future votes involve awarding multiple Super Bowl sites at the same meeting. They also floated the idea of rotating the host city between AFC and NFC cities annually. This would provide the hosts with greater preparation time, and prevent them from having to prepare bids every year. The idea to vote on multiple Super Bowls was implemented the following year, but the AFC/NFC rotation was never implemented.

The Cowboys entered the season still having the reputation of "not being able to win the big games" and "next year's champion". The Super Bowl V loss added more fuel to that widely held view. As in the previous season, Dallas had a quarterback controversy as Staubach and Craig Morton alternated as starting quarterback (in a loss to the Bears in game 7, Morton and Staubach alternated plays). The Cowboys were 4–3 at the season midpoint, including a 24–14 loss to the New Orleans Saints at Tulane Stadium. But after head coach Tom Landry settled on Staubach, the Cowboys won their last seven regular season games to finish with an 11–3 record.

Staubach finished the regular season as the NFL's top rated passer (101.8) by throwing for 1,882 yards, 15 touchdowns, and only 4 interceptions. He was also a terrific rusher, gaining 343 yards and 2 touchdowns on 41 carries. Dallas also had an outstanding trio of running backs, Walt Garrison, Duane Thomas, and Calvin Hill, who rushed for a combined total of 1,690 yards and 14 touchdowns during the season. Garrison led the team in receptions during the season (40). (Thomas, upset that the Cowboys would not renegotiate his contract after his excellent rookie year, had stopped talking to the press and to almost everyone on the team). Wide Receivers Bob Hayes and Lance Alworth also provided a deep threat, catching a combined total of 69 passes for 1,327 yards and 10 touchdowns. The offensive line, anchored by all-pro tackle Rayfield Wright, Pro Bowlers John Niland and Ralph Neely, and future Hall of Famer Forrest Gregg, was also a primary reason for their success on offense. Neely had broken his leg in November in a dirt-bike accident, and was replaced first by Gregg and then by Tony Liscio, who came out of retirement.

The Dallas defense (nicknamed the "Doomsday Defense") had given up only one touchdown in the last 14 quarters prior to the Super Bowl. Their defensive line was anchored by Pro Bowl defensive tackle Bob Lilly, who excelled at pressuring quarterbacks and breaking up running plays. Dallas also had an outstanding trio of linebackers: Pro Bowler Chuck Howley, who recorded 5 interceptions and returned them for 122 yards; Dave Edwards 2 interceptions; and Lee Roy Jordan, who recorded 2 interceptions. The Cowboys secondary was led by 2 future Hall of Fame cornerbacks Herb Adderley (6 interceptions for 182 return yards) and Mel Renfro (4 interceptions for 11 yards). Safeties Cliff Harris and Pro Bowler Cornell Green combined for 4 interceptions. Harris added 29 kickoff returns for 823 yards, an average of 28.4 yards per return (3rd in the NFL). They were also helped out by weak side linebacker D.D. Lewis.
