The Steelers won the Super Bowl for the second year in a row on Terry Bradshaw's 64-yard touchdown pass to Lynn Swann and an aggressive defense that snuffed out a late rally by the Cowboys with an end-zone interception on the final play of the game.
In the fourth quarter, Pittsburgh ran on fourth down and gave up the ball on the Cowboys' 39 with 1:22 to play. Roger Staubach ran and passed for two first downs but his last desperation pass was picked off by Glen Edwards.
Dallas's scoring was the result of two touchdown passes by Staubach, one to Drew Pearson for 29 yards and the other to Percy Howard for 34 yards. Toni Fritsch had a 36-yard field goal.
The Steelers scored on two touchdown passes by Bradshaw, one to Randy Grossman for seven yards and the long bomb to Swann.
Roy Gerela had 36- and 18-yard field goals. Reggie Harrison blocked a punt through the end zone for a safety.
Swann set a Super Bowl record by gaining 161 yards on his four receptions.
