• It's a version of a 'skinny post' pass pattern. It was developed by Don Coryell, former head coach of the San Diego Chargers, and then Norv Turner with the Dallas Cowboys.
• It calls for the receiver to run 12 yards straight downfield before breaking inside at an angle.
• The receiver's job is to take whatever angle is necessary to ensure he is between the quarterback and nearest defender.
• "Bang'' indicates a rhythm throw as the QB hits the fifth step in his dropback. The "8'' is the number in the Air Coryell passing route tree.
