0 1 Trap out of Shotgun Ace Slot Offset is a gap scheme power run play built around a pulling blocker who traps the first down lineman on the play side, letting the HB press the hole and read the trap block. The diagram shows the interior offensive line blocking down while a guard or fullback-type wham blocker crosses the formation to kick out the defensive lineman, with the HB taking a quick handoff and reading the trap for the cutback lane. This is a base run play with no route concept attached, so it is a run beater rather than a man or zone beater, and the primary read progression is the HB reading the trap block first, then the play side crease before deciding to cut back behind the pulling blocker.
Key the play side defensive tackle first, if he is crashing hard down the line he is setting himself up to get trapped, squeeze the gap and force the ball back inside. User the middle linebacker and stay square to the trap block, do not bite on the initial flow because the cutback is the counter to overaggressive linebacker pursuit. Watch for a lead blocker crossing the formation before the snap fires, that pulling lineman or fullback is the tell for a trap concept versus a standard zone run. Stack the box with an extra defender against 12 personnel in short yardage, since this play relies on numbers at the point of attack and a heavy box takes away the natural crease. Beat this play with disciplined gap integrity and a defensive tackle who can two-gap or hold his ground, aggressive fronts that overpursue are exactly what the trap block is designed to punish.
Run this out of 12 personnel when the defense is showing base fronts with linebackers stacked tight to the line since the trap block works best against aggressive interior penetration.
Check the defensive tackle alignment pre-snap, if he is shaded heavy into the play side gap the trap block becomes even more effective because his own aggression pulls him into the kick out block.
Use motion or a hard count to bait linebackers into flowing early, this exposes the cutback lane that 0 1 Trap is designed to exploit.
Pair this play with Inside Zone and Outside Zone from the same set so the defense cannot key run direction or gap scheme based on formation alone.
Save this call for early down and manageable distance situations like first and ten or second and short, since the trap concept is a base gap run and not designed for chunk yardage on third and long.
