Prevent Defense
The Prevent Defense is a defensive strategy in American football . The defense tries to prevent a large gain in space, but allows small to medium gains in space. It is usually only played by teams in the lead with little playing time left before the end of the first or second half or when a lot of space is gained for a new first down .
variants
There are two main types of Prevent Defense, the 3-5-3 Prevent Defense and the 4-5-2 Prevent Defense.
In the 3-5-3, three defensive linemen exercise the pass rush , five linebackers or defensive backs cover the near zones and three defensive backs cover the deep zones. The defenders responsible for the nearby zones fall back after the snap so that they have enough space to move towards the ball if it is thrown towards an opponent who is in their zone. The deep defenders are so far from the line of scrimmage that they have enough time to cover every defender who is in their zone when a pass is thrown.
In the 4-5-2 there are four defensive linemen, which means that the defense can put more pressure on the quarterback . Five defensive backs go into man marking and two more defensive backs without an assigned opponent help the other players out when a pass is thrown.
disadvantage
Since the defense tries to prevent large gains in space, the offense can try to move forward by effectively using moves to gain little space and thereby use up the remaining game time, which would prevent a counterattack if the prevent defense fails.
