Quick Reference
Breakdown
Strong Flood floods the strong side with three route levels stacked vertically: the outside receiver runs a deep vertical, the slot runs an out breaking to the flat, and the inline receiver clears out on an out route at the sticks level, while the backside runs a deep out and a shallow drag underneath. The lone red route shows the TE or inside receiver working an in-cut across the middle as a blocking/route conflict for underneath defenders. This is a classic Cover 3 beater that stresses the strong side flat-to-deep zones with three-level spacing, forcing the deep third defender to choose between the vertical and the flat route. Primary read progression starts with the deep vertical on the strong side, works down to the flat route underneath it, then comes back to the backside drag or out as the checkdown.
Defensive Reads
Pre-snap, check the cornerback depth on the flood side. A press corner with no deep safety help over the top signals man coverage and opens up the vertical route immediately. Watch the strong side deep third defender after the snap. If he sinks with the vertical route, the flat route underneath should come open in the void behind the flat defender. Look for a linebacker or nickel defender sitting in a zone drop on the drag route crossing the middle since a user controlled lurk defender can jump this in-cut and bait a turnover. Cover 3 with a hard rotating safety to the flood side shuts this down fast, so if you see that rotation pre-snap, be ready to check into a backside beater instead. Cover 4 or Cover 2 shells with two deep defenders can bracket the vertical, making the flat and drag your primary targets against those looks.
Usage Tips
Pre-snap, identify the deep safety alignment to confirm single-high or split-safety shells before committing to the strong side flood. If you see two deep safeties rotating late, be ready to work the backside drag or out since the flood side gets extra help. Use hot routes to convert the inline out route into a corner route against Cover 3 to attack the seam if the flood is well defended. This play hits hardest on second and medium to second and long, giving the quarterback time to work through the three-level read without needing an immediate checkdown. Pair Strong Flood with Flood Switch in your play calling sequence so the defense cannot key on the same flood side every snap, and mix in Curl Flats from the same set to attack shallow zone drops with a different picture.
