SFT Mtn Sail Sit is a bunch-based sail concept out of Shotgun Bunch Spread Nasty that uses pre-snap motion to shift the bunch alignment before the snap. Off the diagram, one receiver runs a deep clearout route to the sideline, a second receiver runs the sail route breaking outside underneath that clearout, and the third receiver in the stack runs a vertical seam that bends into a sit route in the intermediate zone, creating a high-low stretch on the flat and hook defenders. This is a zone beater built to attack Cover 2 and Cover 3 shells by stacking three levels of horizontal and vertical stress on one side of the field, with the sit route as the primary read against zone drops and the sail route as the answer versus aggressive flat corners.
Key the flat defender immediately after the snap, if he sinks into the sit route window rather than widening with the sail route the quarterback should hold the ball and let the play develop. Watch for user-controlled defenders lurking underneath the sit route, since this is the primary read a savvy defender will sit in that throwing lane to bait an interception. Identify safety depth pre-snap, a two-high shell that rotates late into Cover 3 can be exploited by the deep clearout route pulling the corner or safety away from the underneath sit route. Look for man coverage indicators through the pre-snap motion, if the defense blitzes off the edge with man coverage behind it, get the ball out quickly to the sit route before the pocket collapses. This play struggles against aggressive Cover 4 or Cover 6 shells where an extra defender can rob the sit route while the flat defender still carries the sail route, so avoid calling this against heavy pattern-match zones.
Use the pre-snap motion to identify man versus zone before the snap, if the defender travels with the motion man you are getting man coverage and should target the sit route sitting down in the void behind underneath defenders.
Against Cover 3, read the flat defender first, if he widens with the sail route the sit route will settle into the open window for an easy completion.
Against Cover 2, the deep clearout route occupies the safety while the sit route sits underneath in the natural seam between the corner and safety, giving the quarterback a clean throwing lane.
This play works best on second and medium or third and short to medium since the sit route is designed to be an efficient, high-percentage completion rather than a big chunk play.
Pair this play with Mtn Slot Hitch or Mtn Slot Cross from the same set to keep defenses guessing between quick underneath throws and this sail-based zone beater, forcing linebackers to respect multiple route depths from the same formation.
