Tight Y Off Flex is Singleback's hybrid 11 personnel look that splits the difference between a condensed run set and a spread passing set. You get a tight end attached to the line on one side, the Y off the ball in a flexed alignment away from the core, and a flanker plus split end stretching the numbers. That off-ball Y is the whole point of the set: he is not covered up by a tackle, so he can motion, arc release, insert on Counter Y, or run the full route tree without getting jammed by a defensive end. Compared to standard Singleback Wing or Tight sets, you keep the same heavy run shell but gain a detached receiver who reads as a mismatch target against base personnel.
The run game here is as complete as it gets in Singleback: 0 1 Trap, Wide Zone, Inside Zone Split, HB Dive, HB Slam, Counter Y, HB Zone Wk, HB Toss, and Jet HB Power give you gap, zone, and pin-pull answers from the same alignment. That variety matters because the defense cannot key the Y's alignment for run direction when Counter Y pulls him one way and Split Zone sends him the other. The Gadget and SLWR tags show up in Jet Sweep, Zone Fake Jet, PA Jet Sweep, and Jet HB Split Zone, where pre-snap jet motion forces the defense to spin coverage or commit a flat defender before the ball is ever snapped.
Through the air, this set leans heavily on play action off the run identity. PA Boot Slide, PA Deep Out, and PA Y Middle Screen all sell the same downhill action you are already running, while Shallow Cross, Stick Spacing, Rams Pivot Dig, Under Z Curl, and Smash Hammer cover the full man beater and zone beater spectrum. Because the Y is flexed, defenses that stay in base personnel are stuck putting a linebacker or box safety on him in the slot, which is exactly the isolation you want on Stick Spacing and Rams Pivot Dig. If they check to nickel, you run Jet HB Power and Counter Y into a lighter box.
Use jet motion on early downs to diagnose coverage: if the defender chases the motion man across the formation, you are in man and Shallow Cross or Rams Pivot Dig is live. If the defense passes him off, run Stick Spacing or Under Z Curl into the zone windows.
Establish Wide Zone and Inside Zone Split on first and second down before calling PA Boot Slide or PA Y Middle Screen. The play action only works once the linebackers are stepping downhill.
On third and medium, motion the flexed Y inside and hot route him to a slant or option route to attack the linebacker matchup directly. That is the cleanest way to convert against base personnel.
Against heavy box looks (eight in the box, single high), check to Jet Sweep or PA Jet Sweep to attack the edge horizontally rather than banging Trap or HB Dive into the teeth.
Block the running back on Rams Pivot Dig and Smash Hammer when you expect pressure. Losing the check release costs you very little because both concepts are built around the outside and intermediate levels anyway.
