RPO Zone Peek is a run-pass option built off an inside zone blocking scheme out of Shotgun Spread 10 personnel. The QB reads the play side second level defender (usually a linebacker or slot defender) after the snap: if that defender steps up to fill the run gap, the QB peeks and throws to the vacated area, and if he sits back in coverage, the QB hands off or pulls it to run the zone lane. It functions as both a run play and a light zone beater since it punishes linebackers who crash down on the run fit.
Pre-snap, identify if the defense has a linebacker cheating toward the box or sitting in a passing depth alignment, since that determines whether the RPO throw or the run is live. If the defense shows a two high safety shell with linebackers staying at normal run depth, the QB should lean run since the peek defender is not conflicted. Man coverage with press corners on the outside makes the peek throw riskier since the flat or slot defender may have safety help underneath, so crashing linebackers become the priority key. User-controlled defenders who spy the mesh point or sit the peek route with a linebacker will shut this down, so mixing in play-action rollouts like PA Slot Slide punishes that aggressive keying. A fast inside blitz or nano blitz package beats the zone run before the mesh point develops, so audible to a quick game concept like Quick Slants if you see a heavy blitz alignment pre-snap.
Pre-snap, check the box count and see if the defense is in a run-heavy front with light second level numbers, since that tells you the give read is live.
Watch the slot or peek defender before the snap to confirm he is aligned to actually threaten the run fit, otherwise the RPO read becomes obvious and slow.
Use hot routes sparingly here, since the base design already gives you a clean conflict defender, but you can adjust the backside receiver to a quick out if you are facing man coverage.
This play works best on early downs (1st and 2nd) when defenses are guessing between run and pass, and it loses value in obvious passing situations like 3rd and long.
Pair this with Inside Zone and RPO Peek Slant in the same series so the defense cannot key on formation tendencies, forcing linebackers to freeze on every snap.
