HB Off Tackle out of Singleback East 12 personnel is a gap-scheme run play that sends the HB behind the playside tackle and TE for a downhill hit with a lead blocker sealing the edge. The offensive line pulls or combo blocks to create a wall at the point of attack, with the TEs providing extra beef in-line to strengthen the edge against odd fronts. This is a pure run play with no play-action or pass option attached, and the primary read is the playside double team at the tackle and TE, bouncing outside if the alley defender or force player crashes down too hard.
Watch linebacker depth pre-snap: stacked or crept-up linebackers signal a run blitz that can beat this play if your lead blocker gets picked off. Identify the force defender, usually the strong safety or outside linebacker, since his read on the TE's block determines whether you should stick inside or bounce it outside. This play struggles against overload run blitzes and heavy 4-3 under fronts where an extra defender is stacked in the playside gap. It beats light boxes and defenses in nickel or dime packages that are trying to defend pass first, since the numbers advantage at the point of attack becomes easier to exploit. Post-snap, key the playside DE and OLB leverage: if they squeeze down hard to string it out, cut back against the grain since the backside will be thinner.
Run this out of 12 personnel when the defense shows base or heavy fronts, since the extra TE gives you a numbers advantage at the point of attack.
Check the box count pre-snap: if the defense has 6 or fewer in the box, this play has a clean lane and you should stick with your blocking scheme instead of bouncing early.
User the FB or lead TE through the hole to manually clear out the first defender that shows in the alley rather than trusting the AI block.
Pair this with HB Dive and Counter U in your play-calling script so the defense has to respect multiple gap schemes and can't sit on one blitz fit.
Use this on early downs (1st and 10 or 2nd and short) to stay ahead of the sticks, then set up HB Slip Screen or PA Boot Slide off the same personnel once the defense starts crashing the edge hard.
