Mtn Corners is a trips-based deep pass concept out of Shotgun Y Off Trips Pats built to attack the corners of the field with a mix of corner routes and underneath breakers. Motion shifts the trips alignment pre-snap to help identify man versus zone leverage, then the outside receivers stem vertically before breaking to the corner while the shallow crosser occupies the middle linebackers. This is a man beater at its core, since the corner breaks create natural separation against trailing defenders, but it also stretches zone defenders vertically if the safety bites on the underneath route. The primary read progression starts boundary corner route, works to the field side corner route, and checks down to the shallow crosser or motion man if both corners are covered.
Watch the deep safety alignment before the snap, since a single high safety indicates man coverage underneath and confirms the corner routes will have favorable one on one matchups outside. Track the cornerback's press or off alignment on the trips side, because press man invites a quick release corner route while off coverage means the receiver needs extra separation before breaking. Key the middle linebacker's depth and reaction to the shallow crosser, since a linebacker who sinks with the crosser instead of blitzing signals zone coverage and should redirect your read to the field side corner route. Identify user controlled defenders lurking in the flat or intermediate zones after the snap, as a smart user playing a robber technique can jump the corner route break and bait an interception if you force the throw too early. Recognize Cover 3 or Cover 4 shells with corners sitting deep and outside, since these shut down the corner routes and require checking down quickly to the motion man or shallow crosser before the pocket collapses.
Use the pre-snap motion to bait linebackers or nickel defenders into revealing man coverage before the snap, since a defender following the motion man across the formation confirms man principles and green lights the corner routes.
Attack this play on second and long or third and medium situations where defenses are more likely to play off man or single high coverage, giving your corner routes room to break outside without getting squeezed by the sideline.
If you see two deep safeties pre-snap, hot route the backside corner into a deep out or comeback to avoid throwing into a natural zone drop, since Cover 2 shells naturally rob the corner route on the trips side.
Pair this play with Mtn HB Corner or Mtn Y Poco in the same set to keep the defense guessing between different corner route shots, forcing safeties to respect multiple deep outside threats on every snap.
Sequence this play after running Scat or HB Power to set up second and short, since defenses will sell out for the run and leave single high shells that this play is designed to exploit.
