Weak I Close tightens the split of both outside receivers down to roughly the numbers or inside them, which is the entire point of the set. Where standard Weak I sets push a receiver to the sideline and give you true isolation, Close compresses the formation so every route stem starts inside the tackle box extension. That means shorter distances to leverage, faster crossers, and stack releases that eat man coverage alive. Personnel is 21 with the fullback offset to the weak side and the tailback behind the quarterback, so you still get a two back run game with a tight end attached, but the compressed splits force defensive backs into tighter alignments where they cannot press with sideline help.
Open with FB Dive and HB Gut to establish the interior run threat, then run PA Boot Lt and PA Boot Slide off the exact same backfield action once linebackers start crashing.
Against single high looks, go straight to Mesh or Bench Switch and let the compressed splits create the rub, and hot route the fullback to a flat or angle route as your check down against man.
Against Cover 3 or Cover 4, Stick and 94 Will are your reads: work the flat and stick portions first, and only push vertical if the safety cheats down on the run action.
Motion an outside receiver before the snap to diagnose coverage, and if a defender follows step for step, kill the zone beater and check to a crossing concept.
Save PA Post Shot for a second and short or first down after a chunk run when the defense is committed to stopping the ground game, and block the tailback to protect against interior heat.
