Breakdown

Redzone Under is a play-action pass out of Shotgun Trey Open Offset that creates a natural flood concept to the trips side while giving the backside a clean man beater. Off the play fake, the outside trips receiver runs a deep go up the sideline, the middle receiver runs a corner route into the pylon, and the inline tag runs a short out that flattens under the corner, stacking three levels on one side of the field. The backside single receiver runs a flat route off the fake while the running back releases underneath, giving the quarterback a quick answer against pressure or when the deep flood is covered. This is a Cover 3 beater at its core: the flood concept overloads the deep third defender and the flat/corner combo isolates the underneath zone defender, so the primary read starts with the corner route, works to the go route if the corner rotates over the top, and comes down to the flat as the checkdown against a hard blitz.

Defensive Reads

Identify the deep safety alignment before the snap: a single high safety shaded toward the trips side signals Cover 3 or Cover 1, both of which this flood concept is designed to attack. Watch the flat defender to the trips side after the snap, since if he sinks with the underneath out route the corner route window opens up immediately behind him. Key the corner defender's depth at the snap: soft corners at seven or more yards give you the quick out and flat combo before the go route ever needs to be considered. Look for two deep safeties splitting the field pre-snap, which signals Cover 2 or Cover 4 and forces the quarterback to prioritize the corner route into the seam rather than the go route that gets bracketed. Beware of a hard blitz off the edge on the play-action fake, since the backside flat and running back release become mandatory checkdowns to avoid a sack when protection breaks down.

Usage Tips

Use this in the redzone or near the goal line when the field compresses, since the flood concept eats up the shortened space and the corner route becomes a natural fade beater against tight coverage.

Read the deep safety before the snap: if he is shaded toward the trips side, the go route will likely draw a double team, so key the corner route as your first read instead.

Sell the play-action with a full pump and hold before your eyes go to the corner or go route, since defenders keying run fits with linebackers up will bite on the fake and open the flood underneath.

Hot route the backside flat to a quick slant if you are seeing man coverage across the board, since this gives you a rhythm throw against man beaters without waiting on the flood to develop.

Pair this call with Y Corner KO or RZ Short Posts on the next snap to keep defenses guessing between corner routes and post concepts out of the same personnel and formation look.
