High Quality Content by WIKIPEDIA articles! The 1978 Pittsburgh Steelers season was the franchise`s 46th season in the National Football League (NFL). The season concluded with the team winning Super Bowl XIII to become the first franchise in the NFL to win three Super Bowl titles. The championship run was led by quarterback Terry Bradshaw and the team`s vaunted Steel Curtain defense. Bradshaw put together the best year of his career to that point, becoming only the second Steeler to win the NFL MVP award. Ten Steelers players were named to the Pro Bowl team, and four were judged as first-team All-Pros by the AP. Head coach Chuck Noll returned for his tenth season—moving him ahead of Walt Kiesling as the longest tenured head coach in the team`s history to that point.
