Flood floods one side of the field with three levels of route depth to overload a single zone defender or cornerback. From the bunch alignment, two receivers from the bunch release outside and up the seam while the third breaks to a shallow flat/drag route, and the backside receiver runs a deep vertical clear-out that occupies the far safety. The blocking is standard pass protection with the HB checking down before releasing to the flat as a fourth option, giving the QB a clean high-low-low read from deep to short on the flooded side. This is a classic Cover 3 beater that isolates the flat defender and hook defender against three stacked routes.
Read the flat defender first: if he widens to the shallow route without depth, throw the intermediate out route sitting behind him for an easy completion. Check the cornerback on the flood side: in Cover 3, he should sink deep with the vertical clear-out, opening a throwing lane underneath for the deep out and shallow drag. Watch for a two-high safety shell pre-snap, since Cover 2 or Cover 4 puts extra help over the top and takes away the deep out, forcing you to work the underneath shallow route instead. Identify blitz packages before the snap by checking linebacker depth, because a nano blitz or overload pressure to the flood side can beat the protection before routes develop, so have a checkdown to the HB ready. Man coverage with no safety help over the top is a green light to attack the deep out route immediately, since the flood concept stresses man defenders who cannot get depth and width simultaneously.
Pre-snap, identify whether the defense shows a single-high shell or two-high shell before the snap, since Flood is designed to stress a Cover 3 rotation and can get eaten up by a sound Cover 4 or Cover 2 shell with two deep defenders on the flood side.
Key on the flat defender and curl/hook player after the snap: if the corner sinks with the deep out and the flat defender widens with the shallow route, the intermediate crosser sitting behind them is usually open.
Hot route the backside receiver into a quick slant or drag if you see man coverage across the board, since the deep clear-out route is wasted against man and you want a quick answer to beat a blitz look.
Use this play on second and medium to long yardage situations where you expect zone coverage, and pair it in a sequence with Curls Y Swirl or Z Spot from the same set to keep the defense guessing between high-low flood concepts and quick spot drops.
Motion is not shown here but consider using a hot route to speed up the flat route against teams that show Cover 3 sink tendencies, forcing the flat defender to declare early.
