Mtn Corner Slot Choice out of Shotgun Trio Y-Flex sends the backside receiver in motion across the formation before the snap, adding horizontal window dressing to the pre-snap picture. At the snap, the outside receiver on the boundary runs a deep corner route stemming to the sideline, the tight end works a choice route breaking outward underneath, and the inside receiver runs a vertical seam to hold the middle of the field while the running back stays in as an outlet or check release. This is a man beater built on the corner and choice combo, with the primary read starting on the corner route against single high looks and working down to the choice route underneath when defenders sink deep.
Read the safety alignment before the snap, since a single high safety cheating toward the boundary tips Cover 1 or Cover 3 and signals the corner route as the top read. Watch the flow of the defender assigned to the pre-snap motion man, since man coverage defenders will mirror the motion while zone defenders will stay in their landmarks. Key the underneath linebacker depth on the tight end's choice route, since a linebacker sitting shallow forces the choice route to break outside while a linebacker dropping deep opens the inside break. This play struggles against two high safety shells like Cover 2 or Cover 4 where the corner route runs into help over the top, so be ready to check down to the choice route or the running back. Beware of a disguised blitz off the edge on the boundary side, since the corner route takes time to develop and a user-controlled rusher timing the snap can force a quick throw before the route matures.
Use the pre-snap motion to identify man versus zone before the snap, since a defender following the motion man confirms man coverage and opens up the choice route against a trailing linebacker.
Attack single high shells like Cover 1 or Cover 3 with the corner route since the deep third or man defender on the boundary has to respect the vertical seam threat first.
Hot route the tight end's choice route to a quicker option if you see a linebacker sitting underneath in zone, since the choice route naturally settles versus zone and breaks outside versus man.
Pair this play with Mtn Corner Y-drag or Mtn Mills in your call sheet to keep defenses guessing between corner shots and shallow crossers out of the same formation.
Best used on second and medium to third and long situations where the defense is more likely to play zone coverage, allowing the choice route to sit in the soft spot underneath.
