in their history, 51–0 in Week 1 in 1989. The Raiders were frequent opponents of the Steelers during the 1970s playoffs, with Pittsburgh facing the Raiders five consecutive times in the playoffs (1972 (Steelers win), 1973 (L), 1974 (W), 1975 (W), 1976 (L)) that decade. This gave the two teams an unusual familiarity with the other despite being in separate divisions in that decade. The Raiders and Steelers have met one additional time in the playoffs (1983 (L)) for a current record of 3–3 in the postseason. Pittsburgh and Dallas first met in 1960 in the Cowboys' first game as a franchise, with the Steelers winning 35–28. The two franchises have faced each other in the Super Bowl on three occasions (X (W), XIII (W), XXX (L)) with Pittsburgh leading the series 2–1. In the 1970s, Pittsburgh and Dallas were both renowned for stifling defenses named "The Steel Curtain" and "The Doomsday Defense" respectively. Pittsburgh became the first team to achieve three Super Bowl wins when it defeated Dallas in Super Bowl XIII, and the first team to achieve four Super Bowl victories a year later when they defeated the Rams. Dallas defeated the Steelers in Super Bowl XXX to become the second team behind San Francisco to win five Super Bowl Championships. Ten years later, Pittsburgh would join Dallas and San Francisco to become the third team to reach that milestone when they defeated the Seattle Seahawks in Super Bowl XL. Three years later, the Steelers would become the first team to win a sixth Super Bowl, achieving that milestone in the 2008–09 season. They played against the Arizona Cardinals in Super Bowl XLIII, with a 27–23 comeback victory. The Broncos have competed in eight playoff games against the Steelers, the most of any team against the Steelers. With the most recent meeting in the playoffs for the 2015 season, the record is 3–5 in favor of Denver. The rivalry with the New England Patriots is more recent. The two clubs met thirteen times 1972–95 with the Steelers winning ten, including five in a row. But in the 1996 season the two met in the playoffs for the first time and the rivalry changed, as the Patriots defeated the Steelers 28–3 in the AFC Divisional Playoffs in January 1997. The next year the Steelers edged New England in overtime 24–21 and won in the divisional round 7–6. Since then,
