Breakdown
Double Ins is a trips-side passing concept out of Shotgun 4WR Trips Strong that isolates the boundary WR on a deep comeback while the trips side stacks two in-breaking routes underneath a vertical clear-out. The outside trips receiver and slot receiver both run 12-15 yard in routes that sit in the same window at different depths, with the third trips receiver running a vertical seam to occupy the deep defenders and create the horizontal stretch. This is primarily a zone beater that attacks the middle of the field between the underneath zone defenders and the deep safeties, with the primary read progression going from the deep in route to the shallow in route, then working back to the comeback route on the backside if the trips window is taken away.
Defensive Reads
Presnap, check safety depth and spacing because two deep safeties with soft outside corners is a green light for this concept, while a single high safety with aggressive underneath zone defenders can clog both in routes. Watch the middle linebacker's depth and drop angle since he is the key defender who can jump the shallow in route if he sits instead of dropping with the vertical clear-out. Key on the slot corner's technique presnap: if he is playing inside leverage in man coverage, the deep in route has a natural rub advantage off the formation traffic. User the deep middle safety to rob the in route window if the offense is throwing this concept repeatedly, since both in routes cross through the same intermediate zone. Blitz packages that bring extra rushers off the edge can beat this quickly because the routes take time to develop, so a well timed nano blitz or edge pressure forces the quarterback to speed up his read before the in routes are open.
Usage Tips
Presnap, identify whether the defense is showing two-high or single-high safety look because this concept thrives against split safety shells that leave a soft spot between the hash and the numbers. If you see man coverage with no safety help over the trips side, hot route the vertical clear-out receiver to a deep post or fade to punish the leverage instead of settling for the in routes. Use this on second and medium to second and long since the in routes need time to develop and the sticks are usually beyond the shallow in breaker's depth. Pair this with Double Slants or Stick X-Slant from the same set to keep the defense guessing between quick underneath throws and the deeper in route combo. Against zone heavy defenses, throw the deep in route first since it settles right behind the linebackers and in front of the safeties for an easy completion window.
