WR Corner out of the I Form Wing 22 personnel shows a three level route concept to the closed side. The outside receiver stems vertical then breaks hard to the corner, the wing/TE runs a deep out that turns upfield into a corner route of his own creating a natural high low stack, and the backside receiver takes off on a deep drag that clears underneath from the opposite side of the formation. This is a man beater built to attack the flat and deep quarter with two receivers occupying the same zone, forcing a defender to pick one. Primary read progression starts with the outside corner route, works down to the wing's corner breaking behind it, and finally to the drag as the checkdown against pressure.
Pre-snap, identify if the closed side corner is aligned inside or outside leverage, outside leverage invites the corner route to break open against the sideline. Check safety depth before the snap, a single high safety cheating to the play side can jump the outside corner route so be ready to check to the wing's route or the drag. Post-snap, watch for a user controlled defender sitting in the flat trying to jump the wing's corner route, if he bites hard the outside corner route stays open longer. Cover 3 with a hard flat defender and a deep third defender staying disciplined can take away both corner routes, look for the drag to bail you out against this shell. Man coverage with no deep help is the easiest shell to beat, the double corner concept overloads a single defender's zone leverage and creates a natural pick situation on the break points.
Take a pre-snap look at the corner and safety alignment on the closed side, if the corner is playing tight man with no safety help over the top the outside corner route wins immediately on the break.
Against zone shells with a deep half or deep third defender sitting outside, work the progression down to the wing's corner route since it settles behind the shallow flat defender and in front of the deep defender.
Use the deep drag from the backside as your answer versus pressure looks, it clears the underneath zone fast and gives the quarterback a safety valve if the corner routes are covered.
This play pairs well with Curls or TE Post from the same set since both hold safeties and linebackers with similar initial keys before breaking away from the corner concept, keep defenses guessing by mixing in HB Lead or HB Power O from the same personnel to sell run first.
Best used on second and long or third and medium when you need a explosive gain, the double corner look stresses defenses that are playing single high or two deep with soft corners.
