Open Flex Close

Open Flex Close is an 11 personnel look out of the Pistol that detaches the tight end from the core of the formation and aligns him in a flexed position a few yards off the tackle, while the three receivers are spread to create an open, spread-style surface. Unlike the more traditional Pistol sets that keep the TE attached as an in-line blocker, this set turns the tight end into a hybrid chess piece. He is close enough to crack, arc, or seal on the edge in the run game, but loose enough to release cleanly into seams and flats without getting jammed by a defensive end. The Pistol alignment keeps the running back directly behind the quarterback, which disguises run direction and makes the play-action and RPO menu look identical pre-snap.

The real value of Open Flex Close is how it stresses defensive personnel matching. Defenses that stay in base to respect the downhill Pistol run game leave a linebacker or safety isolated on the flexed TE, which is exactly what X Seam and Motion Counter Y are built to punish. Defenses that answer with nickel or dime to cover the three receivers get run at with HB Dive, Inside Zone Wk, and Motion Zone Split, where the flexed TE creates an extra gap and a better blocking angle than a standard slot receiver ever could.

The Gadget tag reflects the heavy motion and misdirection built into the set. Motion Zone Split and Motion Counter Y use pre-snap movement and backside blocking to change the strength of the formation, while PA Pin Deep, Mtn PA Portland Wheel, and PA Boot sell the Pistol run action before attacking deep or on the perimeter. RPO Read Flat Wheel ties everything together, giving you a post-snap answer against defenders who cheat toward the run fit or overplay the flat.
