This game matched two of the NFL's best defenses – Pittsburgh's Steel Curtain against the Purple People Eaters of Minnesota – and two legendary quarterbacks: Terry Bradshaw and Fran Tarkenton, respectively.

However, the Steelers dominated the game, recording the first safety in Super Bowl history, and limiting the Vikings to Super Bowl lows that still stand (as of 2010) of nine first downs, 119 yards of total offense, and 17 rushing yards. The Steelers also tied Super Bowl records for the least rushing first downs allowed and the least passing first downs allowed. It was the first Super Bowl to have a safety scored. Tarkenton was held to only 11 out of 26 completions for 102 passing yards, no touchdown passes, and tied a then Super Bowl record with three interceptions. Furthermore, Pittsburgh became the second Super Bowl team after the Miami Dolphins in Super Bowl VII to hold their opponents' offense scoreless; Minnesota's only score came on a blocked punt, and they did not even score on the extra point attempt. The Steelers accomplished all of this with two backups on defense: linebackers Ed Bradley and Loren Toews replaced injured starters Andy Russell and Jack Lambert for most of the second half.

Meanwhile, Pittsburgh had 333 yards of total offense. Steelers running back Franco Harris, who ran for a Super Bowl record 158 yards (more than the entire Minnesota offense) and a touchdown, was named the Super Bowl's Most Valuable Player.

Noll rebuilt the Steelers through the NFL draft, selecting defensive tackle Joe Greene in his first season as head coach. In 1970, Noll drafted quarterback Terry Bradshaw and cornerback Mel Blount. In 1971, linebacker Jack Ham, defensive tackle Ernie Holmes, defensive tackle Dwight White, and defensive back Mike Wagner were selected by the team. Running back Franco Harris was drafted in 1972. And in 1974, the Steelers picked linebacker Jack Lambert, center Mike Webster and wide receivers Lynn Swann, John Stallworth and defensive back Donnie Shell as a free agent. Bradshaw, Webster, Swann, Stallworth and Harris ended up being hall of fame players on offense, while the others formed the core nucleus of their "Steel Curtain" defense, including future Hall of Famers Greene, Ham, Blount and Lambert.

But en route to Super Bowl IX, the Steelers had started the regular season slowly, as Bradshaw and Joe Gilliam fought to be the team's starting quarterback. Gilliam had started for the first four games of the season, but Noll eventually made Bradshaw the starter. Although Bradshaw ended up completing only 67 out of 148 passes for 785 yards, 7 touchdowns, and 8 interceptions, he helped lead the team to a 10-3-1 regular season record. The Steelers main offensive weapon however was running the ball. Harris rushed for 1,006 yards and five touchdowns, while also catching 23 passes for 200 yards and another touchdown. Running backs Rocky Bleier, Preston Pearson, and Steve Davis also made important contributions, gaining a combined total of 936 yards and eight touchdowns.

Greene won the NFL Defensive Player of the Year Award for the second time in the previous three seasons, and he and Greenwood were named to the Pro Bowl. Both of the team's outside linebackers, Ham and Andy Russell, had been also selected to play in the Pro Bowl, while Lambert already had two interceptions for 19 yards in his rookie year. In the defensive backfield, Blount, Wagner, and Glen Edwards made a strong impact against opposing passing plays.

As many predicted, the game was low scoring; both teams failed to score a touchdown or a field goal until the third quarter and ended up with the second lowest total of combined points in Super Bowl history.

The first quarter of the game was completely dominated by both teams' defenses. The Vikings were limited to 20 passing yards, zero rushing yards, and one first down. The Steelers did slightly better with 18 passing yards, 61 rushing yards, and four first downs. Pittsburgh even managed to get close enough for their kicker Roy Gerela to attempt two field goals. But Gerela missed his first attempt, and a bad snap prevented the second one from getting off the ground.

The Vikings later threatened to score when Tarkenton led them on a 55-yard drive to the Steelers 20-yard line. With 1:17 left in the half, Tarkenton threw a pass to receiver John Gilliam at the 5-yard line, but Steelers safety Glen Edwards hit him just as he caught the ball. The ball popped out of his hands and right into the arms of Mel Blount for an interception.

The first was a key 30-yard pass completion from Terry Bradshaw to tight end Larry Brown. Brown fumbled the ball as he was being tackled, and two officials initially ruled the ball recovered for the Vikings, but head linesman Ed Marion overruled their call, stating (correctly as noted in television replays) that Brown was downed at the contact before the ball came out of his hands. Another third down pass to Bleier advanced the ball to the Vikings 5-yard line. The Steelers gained just one yard with their next two plays, but on third down Bradshaw's 4-yard touchdown pass to Brown gave the Steelers a 16-6 lead with only 3:31 remaining.

Harris finished the game with 34 carries for a Super Bowl record 158 yards and a touchdown. Bleier had 65 rushing yards, and two receptions for 11 yards. Bradshaw completed nine out of 14 passes for 96 yards and a touchdown. Foreman was the Viking's top offensive contributor, finishing the game as the team's leading rusher and receiver with 18 rushing yards and 50 receiving yards.
