HB Off Tackle out of Shotgun Trips X Nasty is a straightforward gap run designed to hit the edge with a lead blocker leading through the hole. The diagram shows the HB taking a lateral step before cutting upfield off tackle, following the double team and down blocks from the offensive line to seal the edge defender. This is a run play with no route concept to read, so the primary progression is simply following the HB path and reading the play side blocking to decide between the designed hole and a potential bounce outside.
Pre-snap, count defenders in the box and check if the defense has shifted toward the trips side, which can weaken the off tackle run fit on the backside. Look for linebackers creeping up to the line of scrimmage, which signals a run blitz that can beat this play if not accounted for with the right protection or blocking assignment. Post-snap, key the edge defender and outside linebacker to see if they are getting sealed or if they are penetrating and forcing the HB to bounce outside. Watch for user-controlled defenders spying the HB or flowing hard to the play side gap, since a good user player can blow this play up if the blocking is slow to develop. This play struggles against gap-sound fronts and disciplined edge defenders who stay square, but it can gash light boxes and defenses that overcommit to pass coverage from Trips looks.
Check the box count before the snap and confirm you have a numbers advantage in the box relative to the defensive front.
Use this play on early downs like first or second and short to medium yardage to stay ahead of the chains without tipping your hand.
Pair this with Inside Zone and HB Mid Draw from the same Trips X Nasty set so the defense cannot key on a single gap or blocking scheme.
If the defense shows a stacked box or overloaded run blitz look, audible to a pass concept like Quick Unders or Hi Lo Cross to punish the aggression.
Use manual control on your lead blocker at the snap to help seal the edge defender when the defense sends extra run support to that side.
