Breakdown
Cluster Bunch is a five man route concept out of a tight bunch alignment on the right side with a single receiver split to the left. The bunch releases into a flood combo: the outside receiver runs a deep Go, the middle bunch receiver breaks off a quick Out to the flat, and the inside bunch man climbs a Corner route to attack the void behind the Out. The single receiver to the left runs a deep crossing route that settles into a Flat/Comeback look, giving the offense a five level stretch from the flat all the way to the deep sideline. This is a man beater built on natural rub traffic from the bunch, and the primary read progression starts with the Corner route working outside leverage defenders, then works down to the flat Out, and checks back to the crossing route as the outlet against man coverage.
Defensive Reads
Watch the depth of the corner aligned over the bunch pre-snap since a tight press alignment signals man coverage and increases risk of getting picked on the rub route. Identify if the defense is playing Cover 3 with a single deep third defender, because the flood concept with the Go, Corner and Out routes overloads that one defender and forces a coverage bust. Key the flow of the middle linebacker after the snap, since a fast drop to the flat can jump the Out route and cut off the shortest read in the progression. Look for a user controlled defender sitting in the shallow zone or lurking near the crossing route, as this is the most common way defenses take away the checkdown against this concept. If the defense shows two deep safeties rotating hard to the bunch side pre-snap, expect help over the top on the Corner and Go routes, which should push your progression to the single receiver crosser or flat route instead.
Usage Tips
Use pre-snap motion or a quick glance at the corner over the bunch to confirm man coverage before the snap since the rub concept is most effective against man defenders who have to fight through traffic. If you see two high safeties with the corners playing tight off the bunch, expect a man beater bonus since Cover 2 man leaves seams for the Corner route to work behind underneath defenders. Hot route the single side crosser into a deeper Dig if you diagnose zone coverage, since it gives you a better answer against zone drops than the shallow crossing route. This play pairs well with Mesh Whip or Mesh Post out of the same Cluster set because both threaten similar horizontal stress but attack different levels, keeping defenders guessing pre-snap. Best used on third and medium to third and long where the Corner and Go routes can pick up chunk yardage against man coverage, or in the red zone where the flat Out and Corner combo creates natural pick opportunities in tight man coverage.
