Mtn PA Flood is a play-action flood concept out of Shotgun Trey Open HB Str that stacks three routes to the closed side of the field. The backside receiver runs a corner route stemming vertically before breaking outside, the middle receiver runs a deep vertical seam, and the underneath receiver runs a flat route that flat outs to the sideline, creating a high low low flood read on one side. The lone receiver to the open side runs a comeback out route at intermediate depth, giving the QB a bailout option away from the flood. This is a classic Cover 3 beater since it floods one third of the field with three levels, forcing the corner and flat defender to choose who to cover while the seam route splits the middle defender, and the primary read progression goes flat to corner to seam based on how the zone defender leverages the flat.
Identify single high safety pre-snap since Cover 3 defenses struggle to defend all three flood levels with only one deep third defender and one flat defender. Watch the flat defender post-snap, if he sits on the flat route the corner route window opens behind him, if he bails to the corner the flat route is wide open underneath. Beware Cover 4 or Cover 2 shells with two deep safeties since they can double up the flood side and force the QB to check down to the backside comeback route. Key on blitzing linebackers off the edge since the play action fake can leave the offensive line vulnerable if the defense brings a nano blitz through the play side gap. User controlled lurk defenders sitting in the middle of the field can jump the seam route, so track any manual defender drifting toward the vertical stem before committing to that throw.
Look for single high safety shells like Cover 3 or Cover 1 before the snap since this flood concept exploits defenders trying to cover three levels with two players.
Use play action from run heavy personnel or after establishing HB Str run tendencies so linebackers bite on the fake and open passing lanes for the flood.
If the defense shows Cover 2 or Cover 4 with two deep safeties, work the backside comeback route since the flood side will be more condensed and harder to isolate.
Pair this call with Mtn Spot Y Corner or Four Verticals in the same set to keep defenses guessing between flood concepts and vertical shots off similar formation and motion looks.
Best used on early downs or second and medium when defenses are more willing to sell out on the run fake, and consider hot routing the flat route to a quick out if you see aggressive slot corner blitzes.
