Weak Flood is a three level flood concept run from Shotgun Doubles that overloads the weak side of the field, hence the name. The outside receiver on that side runs a deep vertical to clear out the corner and safety, the slot receiver runs a quick out to the flat right at the numbers, and the tight end or third receiving option runs an inside breaking route from the backfield area to the flat as well, sitting underneath at a shallower depth than the flat route. On the backside, the isolated receiver runs a simple corner or out breaking route on his own, giving the quarterback a bailout option away from the flood. This is a classic Cover 3 beater because it stretches the deep third defender vertically while overloading the flat defender with two options at different depths, so the primary read progression starts with the vertical clear out to influence the deep defender, then works down to the flat route and finally the underneath route sitting in the void.
Key the flat defender first snap to snap, if he sinks with the underneath route or widens too far with the vertical clear out you have an easy window to the flat or the shallow route behind him. Watch the deep third safety or corner depth pre-snap, if he is playing a soft shell more than ten yards off, expect him to be late getting over the top of the vertical clear out route. Identify Cover 3 by checking for a single high safety with corners aligned deep off the line, this shell is exactly what the flood concept is designed to exploit. Man coverage with underneath robbers or a hard blitz shuts this down quickly since the flood routes take extra time to stack levels, so if you see Cover 1 or Cover 0 pressure indicators like a safety creeping into the box, expect the quarterback to bail to the backside isolated route. Watch for a user controlled defender sitting the shallow flood route or lurking the flat, since that user driven read can jump the underdeveloped part of the concept before the ball is thrown.
Use pre-snap motion or a quick glance at the corner and flat defender depth to confirm Cover 3 before the snap, since this play is built to punish that shell.
If the corner sitting in the deep third widens with the vertical route, immediately look to the flat route since the throwing lane opens up instantly.
Hot route the backside isolated receiver into a quick hitch or slant against man coverage looks if you diagnose Cover 1 or Cover 0 pressure pre-snap, since the flood side routes take longer to develop against man.
Pair this call with Curl Flats or Curl Combo earlier in a series so the defense starts respecting shorter zone drops, then hit Weak Flood to attack the same shell vertically once linebackers start jumping curls.
Best used on second and medium to second and long where defenses lean on zone shells, since the flood concept needs a beat to develop and rushed throws against tight man leverage will get contested.
