Mtn HB Slip Screen is a screen pass out of Shotgun Spread Y-Flex Wk with 11 personnel that uses pre-snap motion to sell run action while the offensive line invites the pass rush upfield before slipping out to lead block. The three receivers to the top of the formation run vertical clear out routes (two seams and a corner breaking route) to drag coverage downfield and empty the underneath area, while the motioned receiver sets the edge with a shallow crack path. The HB slips out behind the fake line fire, catching the screen in space with blockers stacked in front. This is a zone beater and blitz beater play designed to punish aggressive pass rush and off man coverage, with the primary read progression starting and ending on the HB screen, since the clear out routes exist solely to occupy defenders rather than serve as actual reads.
Pre-snap, check if linebackers are creeping toward the line of scrimmage or showing blitz indicators, since an unblocked rusher crashing the pocket is exactly what triggers the slip screen success. Watch the motion defender, if a linebacker or slot corner follows the motion man in man coverage, the screen side is leveraged in your favor with blockers releasing into space. Post-snap, key any user-controlled defender who stays home instead of biting on the vertical clear outs, since a disciplined lurk defender sitting in the screen lane can jump the throw. Identify if the defense drops into a zone shell with linebackers reading the quarterback's eyes, because a zone defense that does not overpursue the play fake can rally quickly and limit the screen to minimal yardage. Look for edge defenders who consistently crash hard upfield off the snap, since that aggressive rush lane is the exact gap this screen is designed to exploit.
Call this on early downs or third and short when defenses are keying run action or bringing pressure off the edge, since the slip screen thrives against blitz looks. Use the motion pre-snap to identify if the defense is in man coverage, if the defender follows the motion man across the formation you know you are getting man and the screen has a numbers advantage on the perimeter. Hot route the two vertical seam routes into deeper clear outs if you see two high safeties sitting soft, this keeps linebackers from sitting on the screen lane. Pair this play in sequence with Mtn HB Swing or RPO Alert Screen from the same set to keep defenders guessing between quick game and screen concepts, forcing linebackers to hesitate on their run fits. Avoid calling this against disciplined zone defenses with linebackers that stay square in their drops, since spy linebackers can blow up the screen before blockers get set.
