Wide Slot Right WK is a 3x1 leaning Shotgun set out of 11 personnel that pushes the slot receiver far outside the numbers on the right side, creating a genuinely wide split alignment rather than the tighter trips or bunch looks you get elsewhere in Shotgun. The "WK" tag means the weak side gets isolated: you have a single receiver working alone away from the strength, and that man on an island read is the entire point of the set. With 1 RB and 1 TE on the field, the defense has to declare whether it wants to stay in base personnel and eat a speed mismatch on the wide slot, or go nickel and lose a run fitter against HB Draw, Inside Zone Split, and Counter Y.
What separates this set from standard Shotgun spread looks is the horizontal stretch built into the formation itself. Because the slot is aligned so far outside, zone defenders have to expand before the snap, which naturally widens throwing windows for interior concepts like Mtn Slot Cross, Mtn Z In, and Mtn Post Curls. The wide alignment also makes bubble and swing releases immediate: RPO Glance Bubble and Slant Swing get the ball out with real leverage because the flat defender is already stressed. Against man coverage, that same split gives the slot a two way go with nothing but grass, which is why isolated crossers and choice routes hit so consistently here.
The gadget element is where this set gets dangerous in competitive play. Mtn Double Pass punishes users who bite hard on the underneath throws you have been hitting all game, and the RPO package (Mtn RPO QB Draw, Mtn RPO QB Power) turns any unblocked edge defender into a read rather than a problem. Pair that with the 3DRB tag, meaning you can field a receiving back on HB Slip Screen and PA Deep Choice, and you have a set that runs your entire progression of run, quick pass, RPO, and shot plays out of one alignment with minimal tells.
Check the flat defender's depth pre-snap: if he is aligned inside the wide slot, throw RPO Glance Bubble or Slant Swing immediately for free yards on the perimeter
Against single high looks, run Mtn Slot Cross or PA Deep Choice and user the isolated weak side receiver, since there is no help defender anywhere near that side of the field
Use HB Draw and Mtn RPO QB Draw on second and long when the defense drops into shell coverage, then come back to Strong Flood or Mtn Post Curls once they start crowding the box
Save Mtn Double Pass for a moment after you have hit HB Slip Screen or the bubble concepts multiple times in the same game, ideally in plus territory when the user is jumping underneath
Hot route the tight end to a drag or sit route on Curls and Mtn Z In when you diagnose zone, giving you a reliable checkdown against Tampa 2 and Cover 4 drop looks
