Super Bowl XI regular season record before defeating the New England Patriots and the Pittsburgh Steelers in the playoffs. The Vikings were making their fourth Super Bowl appearance after posting an 11–2–1 regular season record and playoff victories over the Washington Redskins and the Los Angeles Rams. The Vikings became the first team to appear in four Super Bowls, a record they held until the Dallas Cowboys advanced to a Super Bowl for the fifth time in Super Bowl XIII. They had not won in their previous three attempts, losing Super Bowl IV to the Kansas City Chiefs in the final Super Bowl
Super Bowl VIII Cowboys, 27–10, in the playoffs. Meanwhile, the Dolphins defeated the AFC Central champion Cincinnati Bengals 34–16 in the divisional round, and the AFC West Champion Oakland Raiders, 27–10 for the AFC Championship. The Dolphins were the first team to appear in three consecutive Super Bowls. Just as in the regular season, Miami relied primarily on their run game in the playoffs, racking up 241 rushing yards against Cincinnati and 266 vs the Raiders. The ground game was particularly crucial against Oakland, as it enabled them to win despite completing just 3 of 6 passes for 34 yards in the game.
