Breakdown

Mtn PA Flood Under is a play-action flood concept out of Shotgun Tight Slots 11 personnel that sends a jet motion man across the formation pre-snap before the fake, holding linebackers and setting up the run fake read. Post-snap, the outside receiver runs a deep corner route while the inside receiver works a seam to flat combo underneath, creating a true three-level flood to one side of the field with the offensive line sliding to sell the run action. This is a Cover 3 beater by design: the corner route occupies the deep third defender while the seam to flat stretches the flat and hook defenders horizontally, and the primary read progression goes deep corner first, then the flat route underneath if the cornerback squeezes the corner.

Defensive Reads

Watch the play side cornerback pre-snap, if he is aligned with outside leverage and deep, he is likely sitting in the deep third and will be your primary obstacle for the corner route. Track the flat defender after the snap, in Cover 3 he should be dropping to the flat late while reading run action, if he bites hard on the run fake the underneath flat route will be wide open. This play struggles against Cover 4 or Cover 2 shells where a safety can rotate over the top and squeeze the corner route, so check pre-snap for two deep safeties before committing to the deep read. Man coverage with a linebacker or safety following the jet motion man signals a blitz or man beater opportunity, since the flood concept stresses man defenders horizontally on the flat and seam levels. Watch for a lurking linebacker or safety sitting in the flat to jump the underneath route, if you see a defender sinking into that throwing lane post-snap, hold the ball and trust the corner route defender is occupied deep.

Usage Tips

Use the jet motion to identify man versus zone before the snap, if the defender follows the motion man across the formation you are likely facing man coverage and should look to attack the flat route on the underneath crosser.

Sell the play action fake fully by letting the animation play out, this holds linebackers and safeties just long enough for the corner route to clear the deep third defender in Cover 3 shells.

Best called on early downs (first or second and medium) when defenses are more likely to sit in base Cover 3 or Cover 4 shells and less likely to bring pressure that beats the play fake.

Pair this play with Mtn PA Slide or PA Seam earlier in a series so defenders start jumping the flat and seam routes, then hit this deep corner shot when they overcommit underneath.

If the corner route is covered, check down quickly to the seam to flat combo since the play action fake eats clock and a late checkdown can result in a sack if you hold the ball too long.
