Cheat Bunch Switch Flood

Watch the flat defender and curl to flat player pre-snap, since their initial depth tells you if the defense is sitting in Cover 3 or Cover 4 quarters. If the safety stays high and does not rotate down after the motion, expect a two high shell that clogs the deep flood route and forces you to rely on the shallow crosser or drag as your first read. User controlled defenders sitting in the flat or hook zone are the biggest threat, since a smart user can jump the shallow flat and take away the easy completion, so account for that before locking onto the checkdown. Blitz packages that bring extra pressure from the bunch side can disrupt the switch release timing, so identify if the defense is showing an overload look before the snap and be ready to get the ball out on time. Cover 3 with a hard cheating corner rolled to the flood side is where this concept is most vulnerable, since a well timed jump on the deep out or corner route can lead to a big play against you if the quarterback does not see the corner sink late.
