What Is the Stack 5-2 Defense?

The Stack 5-2 Defense is a variation of the traditional 5-2 Defense that aligns the linebackers directly behind the defensive linemen in stacked positions. This alignment improves disguise, simplifies linebacker reads, and provides flexibility against both inside and outside running plays.

History

The Stack 5-2 Defense developed as coaches combined the proven run-stopping ability of the 5-2 Defense with stacked linebacker alignments that allow defenders to react later while disguising their intentions before the snap.

Alignment

A typical Stack 5-2 Defense includes:

Five defensive linemen
Two linebackers aligned directly behind the defensive line
Four defensive backs
