Mtn Out N Up Seam is a motion man beater out of Shotgun Spread Dbl Flex Wk that uses a jet or across motion to the boundary before the snap, shown by the light blue arrow crossing the formation. The backside receiver runs an out and up (shown in gold, breaking outside then stacking vertically) while the two receivers to the play side run a seam and a corner breaking route stacked outside the numbers, with the inside receiver climbing straight up the seam (red) and the outside man working an out and up of his own (gold, short kink into a vertical stem). There is no visible run blocking or lead blocker action at the mesh point, confirming this is a drop back pass concept, and the primary read progression starts with the seam route against man coverage, then works to the out and up as a double move if the corner jumps the shorter break.
Watch the corner over the out and up route pre snap, if he lines up with heavy outside leverage he is inviting the out and expecting to jump it, sit on that route with a user defender to bait the throw. Key the middle linebacker or safety depth on the seam route, shallow depth at the snap means he is likely sitting on that concept and will get a fast break, deep depth signals zone drops that will struggle to cover the vertical stem. If the defense shows two deep safeties with corners playing off at the snap, this is Cover 2 or Cover 4 and the seam will get squeezed by the safety rotation, bail out of this play call and check to a shorter concept. Track the defender assigned to the pre snap motion man, a defender who mirrors the motion across the formation confirms man coverage and should trigger an immediate key on the out and up double move. Look for late blitz indicators from the slot or edge defenders after the motion, disguised pressure timed to the snap can collapse the pocket before the seam route develops, so be ready to hit the underneath route or throw the seam earlier in the progression.
Use the pre snap motion to identify man versus zone before the ball is snapped, if the defender follows across the formation you have a strong indicator of man coverage and should key the out and up as your window.
Against man coverage, trust the seam route first since it forces a linebacker or safety to run vertically with your tight end or slot receiver, this is a big play window versus Cover 1 or Cover 3 match.
The out and up on the backside is a double move built to counter aggressive corners that jump routes, hold this route as a second read on third and long when defenders are more likely to sit on the shorter break.
Pair this play with Mtn Corner or Mtn Smash in the same set to keep defenders honest, since both plays start with similar out breaking stems before diverging, this creates hesitation on your pre snap motion read.
Call this on early downs in medium yardage situations to punish teams that show single high safety looks, since the vertical stress from the seam and the out and up overload one half of the field.
