Football Audible

What is Audible in Football?

The term "audible" is used to describe a pre-snap adjustment. Often, the offense or defense will huddle up and call a play but have to make changes on the fly based on what they see prior to the ball being hiked.

Offensive Audibles

Football Audible

From an offensive standpoint, the quarterback is generally the player that calls the most audibles. After the play has been called, the quarterback might notice that the defense is aligned differently than the offense expected. Upon realizing this, the quarterback might decide to call an audible at the line of scrimmage, verbalizing the changes to the rest of the offense or making hand gestures to ensure that everyone is on the same page. Audibles can range from drastic changes such as changing from a pass play to a run play or simple changes such as altering the route of a receiver.

Audibles also exist for offensive linemen. The center is usually in charge of relaying the audibles to the rest of the offensive line, with the most common adjustment being a modified blocking scheme to account for a blitz (the defense sends extra players after the quarterback rather than having them drop back into coverage).

Defensive Audibles

Defensive audibles are relayed by the middle linebacker, who is often the captain of the defense and responsible for a majority of the play calls throughout a game. Most defensive audibles pertain to coverage adjustments. For instance, if the defense notices that the receivers are aligned in a way that suggests the offense is likely trying to complete a pass deep down the field, the middle linebacker will likely change the original play and tell his defense to switch to a coverage that protects against long passes.
