Flood Drive out of Shotgun Tight Y Off (11 personnel) sends three receivers into a vertical flood on one side while a drive concept works underneath, giving the QB a clear high-low progression. The outside receiver stems vertical then breaks back on a deep out, the TE runs a corner route stacked behind the flat route, and the inside slot runs a shallow drive/flat underneath, while the backside receiver runs a deep post to hold the safety. This is a Cover 3 and Cover 4 beater built to overload one side of the field, with the primary read progression starting on the deep out/corner combo before working down to the flat and drive routes underneath.
Pre-snap, identify if the cornerback to the flood side is playing off man or bailing into a deep third zone, since this route combo eats up defenders who cannot handle the out and corner simultaneously. Watch the flat defender at the snap, if he sinks with the corner route the deep out will be wide open, if he jumps the out route the corner route behind him is the answer. Key the single high safety, if he cheats toward the flood side pre-snap it signals Cover 3 or Cover 4 rotation and the QB should anticipate the deep out sitting down in the void. User linebackers sitting in underneath zones can jump the drive route, so watch for a lurking defender crashing down on the shallow crosser before committing to that read. Man coverage with no safety help over the top is the biggest risk since the corner route can be undercut, so check for two-high shells to confirm this play is live against man beaters.
Look for single high safety alignments or Cover 3 shells pre-snap since the flood concept is designed to stress the deep third defender on the boundary.
Use the deep out as your first read against zone coverage because the corner sitting in the flat zone cannot cover both the out and the corner route breaking behind him.
Against man coverage, work the underneath drive route quickly since the flood side occupies defenders vertically and opens a natural rub for the shallow crosser.
Pair this play with Mesh Spot or Stick from the same set to keep defenses guessing between horizontal stretch concepts and this vertical flood, forcing linebackers to respect multiple route depths.
Best called on second or third and medium when you need a defined progression read and want to attack a defense sitting in zone shells near the numbers.
