Cowboys came back with a touchdown of their own, Roger Staubach threw a last-second interception that sealed a 21–17 win for the Steelers. Lynn Swann had returned from his injuries and racked up four receptions for 161 yards and a TD in the Super Bowl, earning him the title of game MVP. 1976–77: Playoff losses The two-time defending champions got off to a rough start in 1976, losing four of their first five games. The team regrouped and, based on their powerful defense, won their last nine regular season games, five of which were shutouts. For the third consecutive year, a Steelers player (this time Jack Lambert) won the AFC Defensive Player of the Year award. Pittsburgh finished 10–4 and blew out the Colts 40–14 in the divisional playoffs. In the AFC Championship, an injury-plagued Steeler team lost 24–7 to their perennial playoff nemeses and eventual Super Bowl champions, the Raiders. Pittsburgh's 1977 season was a relative disappointment. Bradshaw threw more interceptions than touchdowns, halfback Rocky Bleier had only half as productive a season as he did in 1976, and the famed Steel Curtain defense gave up nearly twice as many points. The team still won the division at 9–5, but lost 34–21 to the Denver Broncos in the divisional playoff. 1978-79: Third and Fourth Super Bowls 1978 The Steelers kicked off with controversy, when during a post-draft mini camp they were caught wearing shoulder pads in violation of league rules. They would lose a draft pick the following year for the infraction. Pittsburgh posted a 14–2 regular season record, best in the NFL. In the playoffs, the Steelers blew away the Denver Broncos and Houston Oilers by a combined score of 67–15 en route to Super Bowl XIII. That game, a rematch with the Cowboys, is considered by many to be one of the greatest Super Bowls of all time. Bradshaw threw four touchdowns, but the Cowboys never were out of it, thanks in part to a fumble recovery for a touchdown by Mike Hegman. After Swann and Harris scored touchdowns 19 seconds apart in the fourth quarter, the Cowboys countered with scores of their own by Billy Joe Dupree and Butch Johnson to pull within four points with 22 seconds left. The Steelers recovered the onside kick and pulled off a 35–31 win. Terry Bradshaw was named game MVP. 1979 The 1979 season was the last season of
