As a coach, Al Davis relied on the philosophy of applying pressure to the opponent in all forms.
Whether defensively or offensively, Davis felt the most affective way to victory was by breaking up the opponent's rhythm, and putting as many points on the board as quickly as possible.
Davis took over as coach of the Raiders in 1963, after having spent time as an assistant coach under Sid Gillman in San Diego. Gillman used a more aggressive passing attack than most teams at the time.
After Davis took his post in Oakland, he updated Gillman's philosophy by implementing a passing attack with a goal of stressing a defensive secondary by throwing the ball downfield with regularity.
He termed his offensive philosophy the "verticle game."
The Raiders found success throughout the decades by running a flamboyant offense that was ahead of its time. Davis' approach relied upon a big-armed quarterback and fast receivers.
His strategy worked beautifully during the Raiders Super Bowl victories as Ken Stabler and Jim Plunkett torched opposing defenses in an era where most teams simply didn't have evolved passing attacks.
