Breakdown
RPO Peek Slant out of Shotgun Trey Open Offset is a run-pass option built off inside zone action to the backfield, with the offensive line executing a zone blocking scheme up front. The isolated receiver on the backside runs a vertical release straight upfield as the peek read, while on the trips side the outside receiver runs a shallow slant and the adjacent receiver works a quick out or flat breaking route underneath. The primary read is the quarterback peeking the backside vertical route first for a big play opportunity before working back to the zone handoff read and the underneath slant/flat combo if the box is stacked.
Defensive Reads
Check the backside safety depth before the snap, if he is shaded away from the peek route or playing deep middle you likely want to take the run read instead of forcing the vertical shot. Count the box defenders, six or fewer in the box favors the run key while seven or more should trigger the pass option to the slant/flat side. Watch for a linebacker spying the mesh point or crashing hard downhill, which signals a run blitz that the RPO is designed to punish with the quick pass. Zone coverage shells like Cover 3 or Cover 4 that keep the underneath defenders sitting flat can be attacked with the shallow slant since it settles into the void between the linebacker and corner. Man coverage on the backside vertical route is where this play becomes a true explosive play threat, so watch cornerback press alignment and hip positioning at the snap to confirm man technique before pulling the trigger on the peek.
Usage Tips
Use pre-snap motion or a hard count to bait linebackers into showing their run fits before the snap, since this play lives and dies on reading numbers in the box. If the safety on the backside cheats down pre-snap, immediately key the vertical peek route for an explosive shot play. Hot route the flat route into a speed out against teams that sit their underneath defenders in zone to create instant separation. This play pairs well with Inside Zone and HB Off Tackle from the same set since the run action looks identical, forcing linebackers to freeze and second-guess their keys. Best called on early downs or short yardage situations where defenses are more likely to load the box and give you the clean give read.
