Mtn Swing Screen out of Shotgun Trey Offset is a designed screen pass built off jet-style motion, with the diagram showing the ball carrier looping from the backfield toward the sideline while the offensive line sets up a wall in front of him. The interior linemen and TE hold their blocks at the line of scrimmage momentarily before releasing to the perimeter, creating a convoy for the swing man as he stretches to the boundary. This is a pure screen play designed to bait aggressive pass rushers and beat man coverage or blitz-heavy fronts by getting the ball out quickly to the flat with blockers leading the way. The primary read is simply the swing man himself: get the ball out fast off the snap and trust the wall of blockers to spring him upfield.
Key the linebacker depth and flow at the snap, since fast-flowing linebackers who chase the motion man will run themselves out of the screen lane if you stay disciplined. Watch for a spy or a defender staying home in the backfield, which is the biggest indicator this screen is diagnosed and will get blown up for a loss. User a linebacker or slot defender and hold at the line of scrimmage instead of biting on the play-action or run fake, then attack the swing man as he catches the ball before blockers set the wall. Cover 3 and Cover 4 shells with aggressive edge blitzes are most vulnerable since the rush creates natural running room for the screen once it develops. Zone defenses with disciplined flat defenders sitting on shorter routes shut this down quickly since they can read the eyes of the quarterback and jump the throw.
Call this against defenses showing pressure indicators like walked-up linebackers or overloaded fronts, since the blitz creates natural running lanes once blockers release outward.
Use the motion pre-snap to identify if the defense follows with a linebacker or defensive back, which tells you if they are in man coverage and susceptible to the screen.
Throw this quickly off the snap, do not hold the ball, since the timing of the screen depends on blockers getting out ahead of the rush before it collapses the pocket.
Pair this with Read Option or Inside Zone from the same Trey Offset set to keep the defense honest on run fits, then hit them with the swing screen when they start crashing hard on run action.
Avoid calling this into disciplined zone defenses with linebackers sitting in short flat zones, since they can read the screen and blow it up before the wall forms.
