Quick Reference
Breakdown
Inside Zone Split is a base zone run out of Singleback U Off Stack with 12 personnel on the field. The diagram shows the offensive line flowing in a zone blocking scheme with double team combo blocks up front while the HB takes a slight split path behind the QB, reading the first level of the defense before picking his gap. Both stacked receivers on the left run straight vertical releases upfield to occupy corners and safeties, clearing space and removing extra defenders from the box. The primary read progression is the HB reading the playside double team block first, then bouncing to the backside cutback lane if the play defenders overcommit.
Defensive Reads
Pre-snap, count the box defenders and check safety depth, this play struggles against eight man fronts or heavy blitz looks with both safeties down. Look for linebacker alignment over the play side guard and center, if they are shaded hard to one gap the cutback lane on the backside opens up. User controlled defenders flowing hard downhill to the mesh point can be baited into overpursuit, letting the HB cut back against the grain for a big gain. Watch for Cover 0 or man blitz shells pre-snap, since the corners will be locked on the stacked receivers with no help, making this a good spot to hot route a vertical into a quicker option if you smell pressure. Zone shells with linebackers sitting flat footed in their drops tend to get gashed by the interior double teams, this play beats those coverages consistently when the defensive line fails to control gaps.
Usage Tips
Use this play on early downs, first and second and short, when you want to establish tempo and keep the defense honest against your play-action shots from this same formation.
Check the box count pre-snap, if the defense has six or more defenders stacked in the box, consider audibling to a passing concept or motioning the HB to check the run.
The two vertical releases from the stack can be hot routed into quick outs or slants if the defense shows Cover 0 or man blitz, giving you a built in answer if you diagnose pressure.
Pair this with PA Boot Slide and PA Dagger U Cross from the same set to sell the run action and hit explosive shots once the defense starts crashing down on inside zone tendencies.
Against light boxes with two high safeties, trust the interior double teams and let the HB press the line before making his cut, patience on the read wins reps here.
