In 1976, the Raiders came from behind dramatically to beat Pittsburgh 31–28 in the season opener and continued to cement its reputation for dirty play by knocking WR Lynn Swann out for two weeks with a clothesline to the helmet. Al Davis later tried to sue Steelers coach Chuck Noll for libel after the latter called safety George Atkinson a criminal for the hit. The Raiders won 13 regular season games and a close controversial 21–17 victory over New England in the divisional playoffs. With the Patriots up by three points in final two minutes, referee Ben Dreith called roughing the passer on New England's Ray "Sugar Bear" Hamilton after he hit Oakland QB Ken Stabler. The Raiders went on to score a touchdown in the final minute to win. They then defeated the Steelers 24–7 in the AFC Championship to advance to their second Super Bowl. In Super Bowl XI, Oakland's opponent was the Minnesota Vikings, a team that had lost three previous Super Bowls. The Raiders jumped out to an early lead and led 16–0 at halftime. By the end, having forced Minnesota into multiple turnovers, the Raiders won 32–14 for their first Super Bowl and post-merger championship.
