Chip Kelly. Option plays At the heart of all option offenses is the option run. This relatively complicated running play may take on many forms. All option runs, however, rely on two common principles: Whereas the traditional running play typically designates the ballcarrier prior to the snap, the ballcarrier in a true option running play is determined by reading the defensive alignment or the actions of defensive players. This may occur at the line of scrimmage or after the ball is snapped. The second principle of the option run is that it must include two or more potential ballcarriers. These individuals each perform a predetermined route, or "track" that poses a unique threat to a defense. By threatening to attack the defense in multiple ways during the play based on the defense's own actions/alignment, the option run forces the opponent to maintain extraordinary discipline. Defenders must focus on their assignments, which stresses the defense and often mitigates its speed, size and aggressiveness. Consequently, option offenses are excellent for undersized teams. Option runs Option running plays are as numerous as the schemes that employ them. However, nearly all option running plays can be characterized as either a double option or triple option. This is determined by the number of choices available during the play. Triple option: In these highly complex running plays, three potential ballcarriers are available. The triple option typically features three components: a "dive" track, a "keep" track and "pitch" track. In its most generic version, the inside/outside veer, the dive track is typically carried out by a running back. At the snap of the ball, this player attacks the line of scrimmage somewhere between the offensive tackles (or end in the outside veer) as designated by the type of triple option play. This player is often the first choice in the triple option. His goal is to quickly attack the defensive interior in order to either pick up yardage or freeze the defense and prevent their pursuit to the outside. This quick surge into the interior of the defense is traditionally called a "dive". The quarterback determines whether to hand the ball to the fullback by reading a "dive key" - usually a defensive end. If the dive key does not try to tackle the running back the quarterback will hand the ball off to him. Alternatively, if the defender attempts to tackle the running back, the quarterback
