Kc Post is a play-action oriented dropback pass out of Shotgun Spread Y-Slot 11 personnel that attacks the deep middle and intermediate zones with a post concept as its foundation. The route combo pairs a deep post from the boundary receiver with underneath crossers and an out or flat route to hold linebackers and flat defenders, creating a natural high low read against zone coverage while also giving you a hard breaking man beater against off coverage. Your primary read progression starts with the post: if the safety bites on the underneath crosser or bails hard to the sideline, throw the post immediately, otherwise work down to the intermediate crosser as your secondary option and check down to the flat or shallow route if both are covered.
Pre-snap, identify single high versus two high safety alignment since single high shells are the primary weakness this play exploits with the post route. Watch cornerback depth at the line, soft or off coverage on the post side signals an easier throwing window while a jammed corner on the line suggests you should look underneath first. Post-snap, key the safety's first three steps, if he crashes down on the crosser or bites on the play-action fake, the post is wide open behind him. Look for user controlled lurk defenders sitting in the passing lane between the numbers, this play struggles against a rat in the middle of the field defender who can undercut both the crosser and the post. Man coverage with a blitz behind it is the biggest threat to this play, since the post takes time to develop and a free rusher can force an early or inaccurate throw before the route breaks.
Motion the slot receiver pre-snap to identify man versus zone based on whether a defender follows across the formation.
Against single high safety shells like Cover 1 or Cover 3, trust the post to win over the top since there is only one deep defender to account for the middle of the field.
If you see Cover 2 or Cover 4 with two deep safeties, be ready to work the underneath crosser or the flat route instead of forcing the post into a squeezed window.
Use hot routes to convert the flat route into a quick out if you diagnose a Cover 3 sky or cloud rotation, giving you a faster access throw against flat defenders sitting on shorter routes.
Pair Kc Post with Kc HB Draw or Kc Under Y-out in your play calling sequence, since defenses that key on the post's play-action shell will bite on the draw fake, and Under Y-out punishes defenders who overplay the post read.
