Prevent defense
What is prevent defense in American football?
How much players usually take part in the prevent defense?
The prevent defense has the task to run out the clock without chances for the offense to complete the pass or score. It is frequent in the fourth quarter when the defensive team has a 7- or more point lead or when their opponents need a pass to gain long yardage.
This defense exploits five fast defensive backs. Its participants must follow all receivers to prevent the catch behind their zone responsibility. This makes the offense try the shorter pass. The battle becomes unequal because the bigger defensive linemen stay in the shadow of the backs. The prevent defense is a type of zone coverage schemes. It also contains the nickel or the half-dollar defenses or any other formation with five and more defensive backs.
