Eagle Front

In modern defense (notably the Dave Aranda and Ron Roberts systems), the Eagle front is an asymmetric adjustment to the Tite front that shifts the defensive line: the frontside end stays in a 4i-technique, the nose shifts to a shaded 1-technique, and the backside end reduces out to a 3-technique on the guard's outside shoulder.

Aranda's Eagle adjustment alters the interior run fit without substituting personnel:

Frontside B Gap Squeeze

The frontside 4i-technique continues to pinch the frontside B gap, forcing zone runs back toward the center.

Backside 3-Technique Pressure

Widening the backside end into a 3-technique puts immediate pressure on the backside guard and closes the backside B gap against cutbacks.

Linebacker Fit & Fold

The shaded nose commands the backside A gap, freeing the frontside inside linebacker to aggressively trigger into the frontside A gap while the backside inside linebacker tracks the ball over the top.

Naming Collisions across Systems

Historically and in other playbooks, 'Eagle' has named a classic 5-2 front (covering both guards with 3-techniques, related to the Double Eagle or Bear front) or the 3-technique reduction of a four-down defense. Coaches must verify the specific defensive line techniques rather than relying solely on the Eagle label.
