Breakdown

Double In lines up in Shotgun Empty Base with 11 personnel, spreading five eligible receivers across the formation with no running back in the backfield. Both the outside receiver at the bottom of the formation and the inline receiver run deep in routes that break toward the middle of the field at the same depth, creating a double in concept designed to overload the underneath zone or beat man coverage with natural rub potential. The two outside receivers on the far boundaries run vertical seam routes to hold the safeties, the slot receiver runs a quick pivot out route, and the primary progression starts with the deep in route breaking from the strong side, moving to the second in route working from the weak side, with the verticals as the alert if the safeties bail early.

Defensive Reads

Read the middle linebacker depth at the snap, if he sinks deep into a zone drop the shallow in route will be undercut so look to the second in route or the vertical routes instead. Identify Cover 3 or Cover 4 shells pre-snap since the in routes are designed to settle into the soft spot between the underneath zone and the deep zone defenders. Watch for a user controlled linebacker sitting in a lurk position in the middle of the field, this defender can jump the in routes if the quarterback stares them down too long. Man coverage with no safety help over the top gets exposed by the rub created near the line, so blitzes that leave a single defender on an island get burned by the pick action. Cover 2 with aggressive underneath linebackers can clog both in routes at once, in that case check down to the vertical routes on the outside since the corners are forced to stay deep.

Usage Tips

Check the safety alignment before the snap, if you see two high safeties sitting deep this concept is built to sit the in routes underneath them for easy completions.

Use the vertical routes on both boundaries to occupy corners and safeties, which opens up the crossing in routes in the intermediate middle of the field.

Against man coverage, target the first in route breaking hard across the field since the rub from traffic near the formation can shake a trailing defender.

Pair this play with Four Verticals or Y Cross from the same set so the defense cannot sit on the in route concept snap after snap.

Best called on second or third and medium since the in routes settle in at a reliable depth that consistently moves the chains.
