Defensive end

Other ends play the position due to their speed and agility; they are used to rush the quarterback.

These ends can time the snap of the ball in order to get a jump on the rush and stop the play.

If they have an outside linebacker besides them that is not in pass coverage, this gives the defensive end more freedom to rush the quarterback.

Defensive ends are also often used to cover the outside area of the line of scrimmage, to tackle ball carriers running to the far right or left side, and to defend against screen passes.

[citation needed] They are used to occupy an offensive lineman, on pass rushing plays to let the outside linebackers get a sack.
