Y-Sail out of Shotgun Doubles is a classic three level stretch to one side of the field designed to attack Cover 2 and Cover 3 shells. The outer receiver runs a deep corner route to clear the top of the defense, the Y (TE/slot) runs the sail route breaking to the flat/intermediate area at roughly 10-12 yards, and the backside receiver on the play side runs a shallow crossing route underneath while the opposite X runs a vertical stem up the numbers. The backfield RB releases into the short flat as a checkdown option, and the primary read progresses from the deep corner route to the sail route to the flat, working high to low based on the safety and corner leverage.
Watch for two high safeties rotating down into Cover 2, since that alignment tips the sail route as the primary answer against the flat defender's outside leverage. If the corner is playing off coverage at the snap, expect Cover 3 or Cover 4 and target the sail route sitting down in the void before the deep third defender can carry it. Key the flat defender or nickel corner, if he sinks with the corner route the sail route will be wide open underneath, if he jumps the sail route the corner route breaks open behind him. Beware of a hard blitz or nano blitz off the edge, since the sail concept takes time to develop and a fast pressure package can force the quarterback off his spot before the deep routes mature. Man coverage with a single high safety is the toughest shell for this concept, since the crossing route becomes the only real answer and it can get picked off by a linebacker sitting in the shallow zone.
Identify the safety shell before the snap, if you see two high safeties rotate hard to Cover 2 leverage, the corner route should be the first read since it will split the seam between the corner and safety. Against Cover 3, hold the deep corner route as a decoy to hold the deep third defender and work the sail route to the flat defender for an easy pitch and catch. Use this on second and medium or third and short to medium since the flat and sail routes give a quick underneath answer if the defense sits deep. Hot route the crossing route to a hitch or slant if you are facing man coverage with no help over the top, since the sail concept naturally beats zone but needs a quicker answer against man match. Pair this with Four Verticals or PA Dagger from the same set to keep defenses honest, since both plays look similar pre-snap but attack the middle of the field differently, forcing linebackers and safeties to hesitate.
