Flood attacks one side of the field with three levels stacked on the same landmark out of Bunch Open Offset. The isolated receiver runs a corner route into the deep third while the bunch releases a vertical seam and a flat route underneath, creating a high low low flood read on the field side. Blocking is standard pass protection up front, and this is a clear Cover 3 beater since it overloads one zone defender with three vertical stems at different depths.
Watch the flat defender and curl to flat zone defender since Flood is designed to put them in an impossible high low bind between the corner and the seam. If the cornerback on the isolated receiver is playing outside leverage with a deep half safety over the top, the corner route window shrinks and you should progress inside to the seam quickly. Man coverage with no safety help over the top gets exposed by the corner route beating a trail defender, so check for single high shells with no clear deep half rotation to that side. Blitz packages that bring a linebacker off the edge can disrupt the timing of the deep corner throw, so key the box count and any late linebacker walk up before the snap. Zone defenses that roll two deep safeties to the flood side can take away both the corner and seam, forcing the checkdown to the flat, so recognize two high shells rotating toward the strength of the bunch as a sign to move on to another concept.
Pre snap, identify if the safety is showing a two high shell or rotating down to single high, since this concept is built to punish single high Cover 3 looks. Your first read is the deep corner route from the backside isolated receiver, then work down to the seam and finally the flat if the corner window is squeezed by an over the top defender. Use this on early down and medium to long distance situations where defenses are more likely to sit in zone shells rather than blitz. Hot route the flat runner into a quicker option against disguised blitz looks if you see extra defenders creeping toward the line pre snap. Pair this with Reload Flood X-Choice or Y Trail from the same set so defenses cannot sit on the flood concept once they start keying the bunch release.
