Off Tackle out of Singleback Y Off Trips is a gap-scheme run play designed to attack the edge just outside the offensive tackle. The offensive line down blocks toward the play side while the fullback or H-back logic is replaced by TE and slot help pulling to seal the edge defender, creating a natural running lane between the tackle and the trips receiver alignment. This is not a man or zone beater since it is a pure run play, and the primary read progression starts with the play side alignment: identify whether the edge defender is squeezed or widened, then read the flow of the second level linebackers to decide between the designed off tackle lane or bouncing outside.
Watch the play side defensive end and outside linebacker pre-snap to see if they are squeezed inside or widened to take away the edge, since a widened alignment kills the natural off tackle lane. Key the safety rotation before the snap, a single high shell with the strong safety creeping down into the box signals extra run support that can beat this play. Post-snap, track the play side linebacker's first step, if he fills downhill immediately without hesitation the defense has likely diagnosed the run and a cutback may not be available. User controlled defenders spying the running back or sitting in the hole between the tackle and trips side can blow up this concept, so be ready to bounce the run outside if you see a user flowing to the point of attack. Look for run blitzes or contain packages from the edge that bring extra defenders off the trips side, since Off Tackle relies on the offensive line winning one on one blocks against a standard front.
Use pre-snap motion or a quick glance at the trips side to confirm the defense is not overloading the play side edge with an extra defender.
Identify base 4-3 or 3-4 fronts with a standard defensive end alignment since this play struggles against heavy edge blitzes or five man fronts that clog the tackle box.
Hot route the trips receivers into quick stalk blocks or leave them on their normal releases to hold off corners from crashing down on run support.
Pair this play with HB Power O and Counter Y in the same set to keep the defense guessing between gap schemes attacking different edges, then mix in HB Dive to punish linebackers who overcommit outside.
Best used on early downs in normal or run heavy personnel situations where the defense has not yet declared an obvious run blitz look, and avoid calling it into stacked eight man fronts.
