and go all the way to the conference championship, where they lost to the Colts. Despite another 8–4–2 season in 1971, the Raiders failed to win the division or achieve a playoff berth. 1972–1978 In 1972, with Wayne Valley out of the country for several weeks attending the Olympic Games in Munich, Davis's attorneys drafted a revised partnership agreement that gave him total control over all of the Raiders' operations. McGah, a supporter of Davis, signed the agreement. Under partnership law, by a 2–1 vote of the general partners, the new agreement was thus ratified. Valley was furious when he discovered this, and immediately filed suit to have the new agreement overturned, but the court sided with Davis and McGah. That year would see the team achieve a 10–3–1 record and another division title. In the divisional round of the playoffs, they were beaten by the Steelers 13–7 on a play that would later be known as the Immaculate Reception. With a record of 9–4–1 in 1973, the Raiders reached the AFC Championship, but lost 27–10 to the Dolphins. In 1974, Oakland had a 12–2 regular season, which included a nine-game winning streak.

In the 1975 season opener, the Raiders beat Miami and ended the Dolphins' 31-game home winning streak. With an 11–3 record, they defeated Cincinnati in the divisional playoff round, but again fell to the Steelers in the conference championship. In 1976, Valley sold his interest in the team, and Davis — who now owned only 25 percent of the Raiders — was firmly in charge. The Raiders beat Pittsburgh in a revenge match on the season opener and continued to cement their reputation for hard, dirty play by knocking WR Lynn Swann out for two weeks in a helmet-to-helmet collision. 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
