Breakdown

Curl Flats out of Shotgun Spread Y-Flex is a three level flood concept to the boundary side paired with a curl and flat combo on the field side. The backside receiver runs a deep dig/post breaking route while the two receivers on the strong side stack a curl and flat, with the near receiver sitting down on the curl and the outside receiver working the flat underneath. This is a zone beater designed to stress cornerbacks and flat defenders in Cover 2 and Cover 3 shells by putting a high low read on the underneath defender, and the primary progression starts with the curl route before working down to the flat.

Defensive Reads

Key the flat defender first since his depth at the snap tells you whether he is sinking to the curl or staying flat footed to jump the flat route. Watch for a user controlled linebacker sitting in the shallow curl window, which signals you need to speed up your progression to the flat. Against Cover 3, the deep third defender to the strong side will often widen with the flat route, opening the curl behind the underneath zone. Man coverage with no safety help over the top is a green light to attack the curl route immediately since the route breaks away from most man defenders. Watch for a blitz off the edge on the strong side since the flat route serves as a built in outlet against pressure looks.

Usage Tips

Use this play on second and medium to second and long when defenses are likely sitting in zone shells rather than pressing man coverage.

Pre-snap, identify if the corner over the flat receiver is playing off or squatting at the sticks, since that tells you whether the flat or curl will be open first.

Hot route the backside dig into a deeper post if you diagnose Cover 3 to attack the deep middle vacated by the flat defender.

Pair this play with Y Stick or All Hitch from the same set to keep the defense guessing between quick game and intermediate zone beaters.

Against Cover 2, work the curl to the seam since the flat defender will widen out, opening a throwing lane between the corner and safety.
