HB Slip Screen out of Shotgun Trey Y-Flex is a designed screen pass that slips the running back out to the flat behind a wall of blockers while three receivers occupy the second and third levels downfield. Off the diagram, the two outside receivers on the left run vertical seams while the middle X breaks over the top on a deep crosser, and the flexed Y on the right runs a deep in that clears the underneath area for the screen. This is a zone beater built to punish teams that drop into coverage on obvious blitz downs or overplay the vertical stems, and the primary read progression is check the RB screen first, then work back to the crossing routes if defenders sniff it out.
Watch for a defensive lineman assigned to spy or drop into a screen zone, since disciplined defensive ends will sit and read the backfield instead of rushing Key the middle linebacker depth at the snap, shallow linebackers who stay home in the box will jump the screen and blow it up for a loss Man coverage with press corners on the outside receivers is dangerous for the offense since those defenders can peel off quickly to the flat once they read run action Look for a defense showing Cover 2 or Tampa 2 shell, as the deep safeties will stay high and the underneath defenders often bite on the vertical stems, leaving the screen wide open User-controlled defenders who jump the crossing routes early can be baited into an easy screen completion if they abandon their flat and short zone responsibilities
Call this on early downs or after establishing inside zone so linebackers are already flowing hard on run fakes, which opens the screen lane
Check the defensive line pre-snap for wide four man rushes since a fast interior push can blow up the screen before blockers get set
If the defense shows Cover 3 or Cover 4 with deep zone drops, trust the screen immediately since underneath defenders will be sprinting to cover the deep in and vertical routes
Pair this play with HB Draw and HB Pump Draw in the same set so the defense has to respect multiple RB-based conflicts out of the same personnel look
Use motion or a quick pre-snap read on the flexed Y side to confirm if a linebacker is spying the backfield, and if so consider audibling to Fake Screen Wheel instead
