Mtn All Curl is a four-man curl concept out of Shotgun Spread Y-Slot Wk with pre-snap motion into the backfield. All four vertical stems break down into curls at roughly the same depth, creating a horizontal stretch that settles into the soft spots of a zone shell, with the boundary receiver curling first as the shallowest option and the field-side routes stacking curls behind him. This is a Cover 3 beater by design, since the curls sit down right in the flat-to-hook window that Cover 3 defenders vacate, and the read progression starts with the near curl and works to the far curl based on where the flat defender and hook defenders open their hips.
Pre-snap, check safety depth and cornerback alignment, two deep safeties with corners playing off suggests zone drops that will let the curls settle for easy completions. Watch the linebacker or nickel defender assigned to shadow the motion man, if he sprints across with the motion it confirms man coverage and the play loses its zone-beating value. Post-snap, identify any user-controlled lurk defender sitting in the middle hook zone, since he can jump the inside curl route and bait a turnover if the quarterback stares it down too long. This play struggles against Cover 1 or Cover 0 man pressure because there is no natural rub or pick to create separation, so expect tight coverage on all four curls if the defense shows man before the snap. Blitz packages that bring extra rushers off the edge can collapse the pocket before the curls fully break, so account for hot routes or a quick check down if the offensive line shows a numbers disadvantage against the pressure look.
Use the pre-snap motion to identify man versus zone, if the defender follows across the formation you are getting man coverage and should look to backside curls sitting down against off coverage rather than trying to sit in a phased defender's face.
Against Cover 3 or Cover 4 zone shells, work your progression from the boundary curl to the field curl, since the hook defenders will widen with the motion and open passing lanes underneath.
Throw with anticipation right as the receiver plants and turns, curls sitting down in zone windows get undercut easily if you wait for full separation.
This play pairs well with Four Verticals and PA Comebacks in the same set, since defenders who key the curl breaks on early downs get burned by the vertical push later in the drive.
Best called on second and medium or third and short to medium, where the sit routes give you a high percentage completion against zone linebackers dropping into shallow hook zones.
