Super Bowl XIII can arguably be called the greatest collection of NFL talent ever to gather for a game. In addition to Coaches Noll and Landry, 14 players would end up being voted into the Hall of Fame: Nine Pittsburgh players: Bradshaw, Harris, Swann, Stallworth, Webster, Greene, Lambert, Ham, and Blount, and five from Dallas: Staubach, Dorsett, White, Wright, and Jackie Smith, who the Cowboys lured out of retirement from the St. Louis Cardinals due to injuries to Cowboy tight ends, most notably, Jay Saldi. Other Hall of Famers who participated in the game were from Dallas: GM/President Tex Schramm, and defensive coordinator Ernie Stautner, who actually was a HOF defensive tackle for the Steelers. Additional Hall of Famers from Pittsburgh included owner Art Rooney, Sr., and son Dan Rooney.

Both teams entered the game with the best defenses in the league (the Cowboys only allowed 107.6 rushing yards per game while the Steelers only allowed 107.8), and each side took advantage of the other team's mistakes throughout the game. But Dallas could not overcome their miscues in the second half.

On their opening drive, the Cowboys advanced to the Pittsburgh 38-yard line, with running back Tony Dorsett gaining 38 yards off 3 running plays. But they lost the ball on a fumbled handoff while attempting to fool the Steelers defense with a reverse-pass play. Receiver Drew Pearson later explained "We practiced that play for three weeks. It is designed for me to hit Billy Joe 15 to 17 yards downfield. We practiced the play so much it was unbelievable we could fumble it. I expected the handoff a bit lower, but I should have had it. Billy Joe was in the process of breaking into the clear when the fumble occurred." The play was similar to the near-turnover by Butch Johnson in the previous game.

After defensive lineman John Banaszak recovered the loose ball on the Pittsburgh 47-yard line, the Steelers attempted 2 running plays with running back Franco Harris carrying the ball, but only gained 1 yard. Then on third down, wide receiver John Stallworth caught a 12-yard pass to the Cowboys' 40-yard line. Then after throwing an incomplete pass, Terry Bradshaw completed 2 consecutive passes, the second one a 28-yard touchdown completion to Stallworth to take a 7–0 lead.

On their next drive, the Cowboys responded by advancing to the Steelers 39-yard line, but were pushed back to their own 39-yard line after quarterback Roger Staubach was sacked twice, and they were forced to punt. Then on the Steelers' ensuing drive, Bradshaw threw a 22-yard pass to Harris and followed it up with a 13-yard pass to receiver Lynn Swann to move the ball to the Dallas 30-yard line. But on the next play, Dallas linebacker D. D. Lewis ended the drive by intercepting a pass intended for Stallworth.

With a little more than a minute to go in the period, Bradshaw fumbled the ball while being sacked by Cowboys lineman Harvey Martin, and defensive end Ed "Too Tall" Jones recovered it. Staubach then capitalized on Bradshaw's mistake three plays later with a 39-yard scoring strike to receiver Tony Hill, tying the game at 7 as the first quarter expired. Pittsburgh sent eight men on an all-out blitz, but Staubach got the pass away just before he was hit by Steelers' safety Mike Wagner. Hill beat Donnie Shell in single-coverage and scored the only first quarter touchdown surrendered by Pittsburgh all season.

The Steelers took possession at the start of the second quarter and advanced to their own 48-yard line. Dallas linebackers Mike Hegman and Thomas "Hollywood" Henderson then combined to score a touchdown on an unusual play. After taking the snap from his 48, Bradshaw collided with Franco Harris and the ball popped loose. Bradshaw scooped it up and rolled to his right, looking to pass, but Hegman ripped the ball out of Bradshaw's hands as Henderson was tackling him and returned the fumble 37 yards for a touchdown, giving the Cowboys a 14–7 lead.

The Cowboys lead didn’t last long. On the third play of Pittsburgh's ensuing possession, Stallworth caught a pass from Bradshaw at the Steelers 35-yard line. He then broke a tackle from defensive back Aaron Kyle and outraced every other defender to the end zone, turning a simple 10-yard pass into a 75-yard touchdown completion to tie the score, 14–14. Bradshaw later explained that Stallworth was not even the primary receiver on the play: "I was going to Lynn Swann on the post," he said, "but the Cowboys covered Swann and left Stallworth open. I laid the ball out there and it should have gone for about 15 yards, but Stallworth broke the tackle and went all the way."

Pittsburgh's "Steel Curtain" defense then dominated the Dallas offense on their ensuing drive. First, Banaszak tackled fullback Robert Newhouse for 4-yard loss. Next, linebacker Jack Ham tackled Dorsett for a 3-yard loss on an attempted sweep. On third down, defensive tackle Joe Greene sacked Staubach, forcing a fumble that bounced through the hands of Steelers' defensive lineman Steve Furness. Cowboys lineman Tom Rafferty eventually recovered at the Dallas 13-yard line. Theo Bell then returned Danny White's eunsuing 38-yard punt 3 yards to the Dallas 38-yard line.

The Steelers began their ensuing drive with Bradshaw's 26-yard completion to Swann. Jones tackled Harris for an 8-yard loss on the next play, but a subsequent holding penalty on Henderson gave Pittsburgh a first down at the Dallas 25-yard line. However, after an incomplete pass and a 2-yard run by Harris, Hegman sacked Bradshaw for an 11-yard loss on third down, pushing the ball back to the 34-yard line. The Steelers then came up empty after kicker Roy Gerela's 51-yard field goal attempt hit the crossbar.

With less than two minutes remaining in the half, Dallas advanced to the Pittsburgh 32-yard line, after starting from their own 34-yard line. But Pittsburgh defensive back Mel Blount intercepted a pass from Staubach and returned it 13 yards to the 29, with a personal foul on Dallas tight end Billy Joe Dupree adding another 15 yards and giving the Steelers the ball at their own 44-yard line. With time running out, Bradshaw completed 2 passes to Swann for gains of 29 and 21 yards, moving the ball to the 16-yard line with 40 seconds left in the half. Then after throwing an incomplete pass, Harris ran the ball to the 7-yard line. Then with just 26 seconds left, Bradshaw completed a 7-yard touchdown pass to fullback Rocky Bleier, giving the Steelers a 21–14 lead at halftime.

The torrid scoring pace slowed during much of the third quarter, as both teams began to assert themselves on the defensive side of the ball. But late in the quarter, a 12-yard punt return by Cowboys receiver Butch Johnson gave Dallas good field position on their 42-yard line. The Cowboys subsequently drove down to the Steelers 10-yard line, mostly with Dorsett's rushing. Then on third down with less than three minutes remaining in the period, Staubach spotted 38-year old reserve tight end Jackie Smith wide open in the end zone and threw him the ball. The pass was a little behind Smith, but it was catchable. However, Smith dropped the pass and the Cowboys had to settle for a field goal from kicker Rafael Septien, cutting their deficit to 21–17. Though Smith played 16 years in the league and is now enshrined in the Pro Football Hall of Fame, he is perhaps best known for his embarrassing blunder on the sport's biggest stage.

Two controversial penalties early in the fourth quarter paved the way for the Steelers to score 14 unanswered points. The Steelers advanced to their own 44-yard line after a crucial 3rd down pass from Bradshaw to tight end Randy Grossman, a 13-yard pass to Swann, and a 5-yard run by Harris. Bradshaw then attempted a pass to Swann, but the receiver collided with Cowboys defensive back Benny Barnes and fell to the ground as the ball rolled incomplete. However, official Fred Swearingen called Barnes for pass interference. Replays showed that it could have been incidental contact, as Swann seemed to run into Barnes. The penalty gave Pittsburgh a first down at Dallas' 23-yard line.

Two plays later, the Steelers faced 3rd down and 4 from the Dallas 17. Henderson sacked Bradshaw for a 12-yard loss, but the play was nullified by a delay of game penalty on Pittsburgh, bringing up 3rd down and 9 instead of a fourth down. Replays clearly showed the whistle blew before the play's onset, plus most of the players pulled up and stopped playing after a whistle sounded, but Henderson claimed, "I didn't hear a whistle until after I had knocked Bradshaw down. Franco Harris confronted Henderson for taunting Bradshaw after the whistle, and on the next play, Bradshaw handed the ball off to Harris, who raced untouched up the middle for a 22-yard touchdown run. The score increased Pittsburgh's lead to 28–17.

The ensuing squib kickoff by Gerela bounced to Cowboy lineman Randy White at the 24-yard line. White, who was playing the game with a cast on his broken left hand, fumbled the ball before being hit by Tony Dungy and Pittsburgh linebacker Dennis Winston recovered the ball at the Dallas 18-yard line. On the next play, Bradshaw threw an 18-yard touchdown pass to Swann, increasing the Steelers' lead to 35–17 with less than 7 minutes left in the game.

Some of the Steelers were already celebrating victory on the sidelines, but the Cowboys refused to give up. On their next drive, Dallas drove 89 yards in 8 plays to score on Staubach's 7-yard touchdown pass to Dupree. Then after Dallas' Dennis Thurman recovered an onside kick at 2:19, Drew Pearson caught 2 passes for gains of 22 and 25 yards as the Cowboys drove 52 yards in 9 plays to score on Staubach's 4-yard touchdown pass to Butch Johnson. With the ensuing extra point, the score was cut to 35–31 with just 0:22 left in the game.

But the Cowboys' second onside kick attempt was unsuccessful. Bleier recovered the ball and the Steelers were able to run out the clock to win the game.

Swann was the leading receiver in the game with 7 receptions for 124 yards and a touchdown. Stallworth recorded 115 yards and a touchdown off just 3 receptions. Stallworth and Swann became the first pair of teammates to each have 100 yards receiving in a Super Bowl and first time two receivers did it in the same game. Dorsett was the top rusher of the game with 96 rushing yards, and also caught 5 passes for 44 yards. Harris was Pittsburgh's leading rusher with 68 yards, and he caught a pass for 22 yards. Staubach finished the game with exactly as many passing attempts (30) and completions (17) as Bradshaw, good for 228 passing yards, 3 touchdowns, and 1 interception. Butch Johnson caught 2 passes for 30 yards and a touchdown, returned 3 kickoffs for 63 yards, and gained 33 yards on 2 punt returns, giving him 126 total yards.
