0 1 Trap is a gap scheme run play out of Shotgun Doubles HB Wk that pulls a play side lineman across the formation to trap the first down lineman while the rest of the front blocks down. The diagram shows the HB starting offset behind the QB and running a hard angle through the A gap off the trap block, with no routes shown for the receivers since this is a designed run. This is a power run play, not a man or zone beater in the passing sense, and the primary read is the HB pressing the trap hole and reading the block on the first down defender before deciding to bounce outside or stick inside.
Watch defensive line alignment pre-snap, since a shaded nose tackle or 3 technique can disrupt the trap timing if he reads the puller. Key the play side linebacker depth, if he is sitting tight to the line he can beat the trap block to the hole and blow up the run. Look for safety rotation into the box pre-snap, a stacked run fit with two safeties down signals the trap will get gang tackled for minimal gain. Post-snap, identify any user controlled defender crashing hard down the line, since that is the classic counter to trap concepts and forces the HB to bounce outside quickly. This run struggles against odd fronts with a plugged nose and versus overload blitzes to the play side, but it beats light shell fronts and defenses that flow hard to zone read fakes.
Use pre-snap motion or a quick glance at the box count to confirm you have a numbers advantage before snapping this run.
Call this against light boxes with six or fewer defenders in the tackle box, since the trap block is designed to remove a fast flowing defensive lineman.
Combine 0 1 Trap with RPO Zone Peek or RPO Power Peek in your play calling sequence so the defense has to respect both the trap action and a peek route off similar HB alignment.
User the fullback or trap blocker manually if you are worried about a nano blitz linebacker crashing the trap hole untouched.
Save this play for early down and medium distance situations where a positive gap run keeps you on schedule, and avoid it versus heavy blitz looks that stack the A gap.
