Mtn H Sneak from Shotgun Split Y Off shows a three level route concept to the trips side with a shallow crosser underneath. The two outside receivers run vertical stems that convert into a corner route and a deep out, while the inline TE releases outside then breaks flat to occupy underneath zone defenders. The lone receiver to the closed side runs a shallow drag across the field, giving the quarterback a quick answer versus man coverage while the deeper routes work zone voids on the backside. This is a play-action style dropback passing concept built to attack both man and zone shells with a clear high low read from the corner route down to the shallow drag.
Watch for two high safeties pre-snap since this concept is designed to stretch deep zone coverage vertically with the corner route. If the defense shows man coverage with a defender shadowing the H back through his motion, expect the shallow drag to be the quarterback's first look. Zone shells with underneath linebackers sitting in hook zones can undercut the shallow drag, so track linebacker depth before the snap. A user controlled defender lurking near the flat can jump the TE's flat route, which forces the quarterback to climb to the deep out or corner instead. Cover 3 with a hard flat defender is the toughest shell to beat here since it clogs both the shallow drag and the flat route simultaneously.
Check the safety alignment pre-snap, if you see two high safeties bail into deep halves the corner route from the outside receiver will have room to work against off coverage. Use motion pre-snap to identify man versus zone by watching if a defender follows the H back across the formation. Against man coverage key the shallow drag as your first read since it creates instant separation off the break. Against zone coverage looks to layer the ball into the deep out or corner route once the underneath defenders flow with the shallow crosser. Pair this play with Mtn H Angle or Mtn H Angle N Out in the same set to keep defenses guessing between quick game and the deeper Sneak concept, especially on second and medium or third and long.
