Tight Flood is a three level flood concept to the same side of the field designed to stretch a Cover 3 cornerback and flat defender vertically. The backside receiver runs a deep dig across the middle as a hot read against zone drops, while the playside stack releases a deep vertical clearout and a corner route that settles underneath it, and the running back releases to the flat to complete the flood. There is no visible extra protection tag on the diagram, so this is a standard five man protection with the flood concept doing the work against zone shells. The primary read progression starts with the corner route in the flood, works down to the flat with the running back, and comes back to the deep dig if the flood side is capped.
Watch the flood side cornerback at the snap, if he sinks with the vertical clearout the flat route to the running back is wide open underneath. Check the middle linebacker depth before the snap, a shallow drop signals he will not be able to wall off the deep dig coming across the field. Identify any user controlled defender flashing down toward the flood side, this usually means a lurk or spy is sitting on the corner route and the quarterback should reset to the flat or dig. Cover 2 shells with two deep safeties tend to shut down the vertical clearout but leave the flat and dig lanes open, so key the safety rotation post snap. Man coverage with press corners on the flood side can disrupt route timing early, so look for the running back to break open late in the down if the corner route gets jammed.
Use pre-snap motion or a hard count to identify if the corner is playing off man or a soft zone before the flood side, since this play is built to attack Cover 3 and Cover 4 zone drops.
If you see two deep safeties splitting the field evenly, expect the flat and corner route to have a clean window since the flood stresses one cornerback and one underneath zone defender.
Hot route the running back to a checkdown or protect the edge if you see a nano blitz coming off the flood side, since the back is your emergency valve when protection breaks down.
Pair Tight Flood with Curl or DBL Stick from the same set so the defense has to respect both a three level flood and a quick game concept, keeping linebackers honest on their zone drops.
On third and medium to long, throw the deep dig if the cornerback jumps the flat route, since that route sits behind the underneath zone flow and punishes a defender selling low.
