Mtn Curls out of Shotgun Y Off Trips Wk shows a three-level curl concept with a full-flat protection call underneath. The backside X runs a deep curl at the top of his stem while the two trips receivers work vertical stems that break down into a shallow drag and a deep curl, giving you a natural high-low read on one side of the field and an isolated curl backside. This is a zone beater built to sit in the soft spots of Cover 3 and Cover 2 zone drops, with the primary read starting on the deep curl to the trips side before working back to the backside curl if the zone rotates away.
Watch for two deep safeties presnap, since Cover 2 zone will squeeze the curl windows and force a quicker underneath read If the corner to the trips side sinks hard into his curl zone, that is a sign of Cover 3 and the deep curl route becomes the primary target in the seam Key the flat defender after the snap, if he widens to cover the shallow drag it opens the backside curl for an easy pitch and catch Man coverage with no safety help over the top can jump the curl breaks, so if you see man alignment presnap consider hitting the drag route quickly before the break A disguised blitz that brings extra rushers off the edge will collapse the pocket fast, so identify overloaded fronts presnap and be ready to throw the curl early before pressure arrives
Presnap identify if the defense shows two high safeties or one high, since this concept thrives against zone shells with soft curl-flat corners
Start your eyes on the trips side deep curl first, that route sits down in the window between the linebacker and safety in most Cover 3 looks
If the flat defender jumps the underneath drag route, come off it and hit the backside curl for a favorable one on one
Use this play on second and medium to third and long situations where sitting routes underneath zone coverage creates easy completion windows
Pair this with Mtn Y Cross or Mtn PA Portland out of the same set to keep defenders guessing between shallow crossers and the curl-heavy concept shown here
