Clearout Rub Return from Shotgun Trey Open uses the trips side to stack a vertical clearout with a rub concept underneath, dragging coverage deep while the return route sits down in the vacated window. The backside receiver runs a deep comeback breaking outside, giving the quarterback a clear outlet away from the trips traffic, while the running back releases to the flat as a check down and screen valve off the play fake. This is primarily a man beater: the rub route picking off man defenders on the return man is the key trigger, but the clearout also stresses zone defenders who have to widen with the vertical release. Primary read progression starts with the return route working back to the ball underneath the rub, then bends outside to the backside comeback if the corner sits in his face, and finishes with the running back in the flat as the last resort.
Key the cornerback aligned over the trips return route before the snap, since a hard press alignment signals man coverage and a likely pick opportunity for the offense. Watch the safety rotation immediately after the snap, if both safeties bail deep into quarters or two high shells, that confirms zone and the user should sink under the clearout instead of chasing it deep. User the linebacker responsible for the shallow rub zone, since that defender must fight through the traffic to reach the return route or the quarterback will find an easy completion underneath. Spy the flat defender on the running back's release, if he jumps the flat route too aggressively the backside comeback route becomes the bigger threat. Disguise blitz timing by delaying the edge rush call, since this concept is designed to hit quickly and a delayed pressure look can bait the quarterback into throwing into a closing window.
Use pre-snap motion to identify man versus zone before the snap, since the rub concept only creates real separation against man coverage with trailing defenders.
If the defense shows two high safeties, expect the corner to sit on the return route, so be ready to climb the progression to the backside comeback immediately.
Attack this play on second and medium or third and short, where the quick-hitting return route can convert on time without needing the deep clearout to fully develop.
Hot route the running back into a wider flat release against teams that bring a nano blitz off the edge, giving the quarterback an instant outlet before pressure arrives.
Pair this play with Clearout Pick Return or Curls Combo out of the same Trey Open look, since the identical initial alignment forces linebackers and safeties to guess between rub and pick concepts before declaring their drop.
