Trey Y-Flex Str is a Shotgun 11 personnel set that stacks three receivers to the strong side, with the tight end flexed off the line as the inside man in the trey. The lone X receiver is isolated on the backside. The running back aligns in the gun next to the quarterback. Standard Trips sets in Shotgun put a slot receiver at the #3 spot. This set puts the Y there instead, which creates a size mismatch on the defender responsible for the inside trips receiver. A nickel corner gives up height and physicality to the flexed TE. A linebacker gives up speed. Because the Y is detached, the defense has to declare its trips check before the snap, and that is where most of the set's value comes from.
The trey alignment pulls coverage toward the strong side and leaves the X in a true one on one on the weak side. The RPO Peek Slant, RPO Zone Peek and RPO Zone Peek Pop concepts attack that isolated side, while the inside zone mesh holds the box defenders. The strong side supports classic trips combos. Spot Quads and Flood Sit stretch flat defenders horizontally. Dagger Sit and Verticals Y Cross stress deep middle safeties. Mtn Fade Smash and Mtn Stick use motion to shift the strength of the formation and flip leverage on the defense.
The set is also a legitimate run and screen look. Inside Zone, Outside Zone, 0 1 Trap and HB Draw punish defenses that spin extra defenders to the trey side. RPO Read FL Screen, Mtn Slot Screen and Jet Chip Wasp work the perimeter against off coverage and blitz. The Gadget, 3DRB and SLWR tags reflect that: a dual threat back and a shifty slot receiver both have multiple ways to touch the ball, and the flexed TE forces nickel and dime packages into bad matchups.
Before the snap, read the safety rotation. If the defense spins a safety to the trey side and leaves the X single covered, run RPO Peek Slant or RPO Zone Peek and throw the slant on any inside leverage corner. If the numbers stay balanced, hand off Inside Zone into the lighter box.
On 3rd and medium against zone, call Dagger Sit or Flood Sit. Against man, audible to Verticals Y Cross or PA Crossers and target the flexed TE on the linebacker he draws.
Against Cover 0 or heavy blitz, hot route the RB to a block or an option route, and audible to Mtn Slot Screen, RPO Read FL Screen or Jet Chip Wasp to get the ball out fast to the perimeter.
Use the Mtn plays (Mtn Fade Smash, Mtn Stick, Mtn Verticals) to diagnose man or zone. If a defender travels across the formation with the motion man, it is man, so throw to the leverage winner.
Once opponents start sitting a user in the middle hook, pull the ball down with 0 1 Trap or HB Draw. Also hot route the Y to a streak to clear the user and open the dig or sit behind him.
