text: 1963–1966 After the 1962 season, Valley hired Al Davis, a former assistant coach of the San Diego Chargers, as head coach and general manager. At 33, he was the youngest person in over 30 years to hold the position of head coach, and the youngest person ever to hold the position of general manager, in professional football. Davis immediately changed the team colors to silver and black, and began to implement what he termed the "vertical game", an aggressive offensive strategy based on the West Coast offense developed by Chargers head coach Sid Gillman. Under Davis the Raiders improved to 10–4, and he was named the AFL's Coach of the Year in 1963. Though the team slipped to 5–7–2 in 1964, it rebounded to an 8–5–1 record in 1965. He also initiated the use of team slogans such as "Pride and Poise", "Commitment to Excellence", and "Just Win, Baby"—all of which are registered trademarks.
  In April 1966, Davis left the Raiders after being named AFL Commissioner. Two months later, the league announced its merger with the NFL. With the merger, the position of commissioner was no longer needed, and Davis entered into discussions with Valley about returning to the Raiders. On July 25, 1966, Davis returned as part-owner of the team. He purchased a 10 percent interest in the team for US$18,000, , and became the team's third general partner—the partner in charge of football operations.
  1967–1969
  On the field, the team Davis had assembled and coached steadily improved. With John Rauch (Davis's hand-picked successor) as head coach, the Raiders won the 1967 AFL Championship, defeating the Houston Oilers 40–7. The win earned the team a trip to Super Bowl II, where they were beaten 33–14 by Vince Lombardi's Green Bay Packers. The following two years, the Raiders again won Western Division titles, only to lose the AFL Championship to the eventual Super Bowl winners—the New York Jets (1968) and Kansas City Chiefs (1969).
