What Is the Prevent Defense?

The Prevent Defense is a situational defensive package designed to stop deep passes and keep the offense in front of the defense. It sacrifices aggressive pressure and run support in exchange for maximum protection against explosive passing plays late in games.

History

The Prevent Defense became a standard late-game strategy as coaches looked for ways to defend Hail Mary attempts and long passing plays when protecting a lead.

Alignment

A typical Prevent Defense includes:

Three or four defensive linemen
One or two linebackers
Five to seven defensive backs
