PA Switch Curl runs a play-action fake out of I Form Slot with 21 personnel, holding the fullback and offensive line in run fake protection while three receivers work a switch release concept to one side of the field. The two outside routes cross paths near the line of scrimmage (the switch element) with one receiver breaking outside on a deep comeback/out while the other climbs into an intermediate curl at the sticks, and the third route runs a deep crosser away from the switch to hold backside coverage. Primary read progression starts with the curl sitting in the void created by the switch release, then works to the deep out breaking to the boundary, using the deep crosser as a late escape valve if the play-action freezes linebackers long enough for it to develop.
Presnap, identify whether the defense shows single high or two high safety alignment since the switch release is engineered to confuse man defenders in Cover 1 and Cover 3. Key the flow of the linebackers after the snap, if they bite hard on the run fake the curl route will sit wide open in the vacated zone. Watch the cornerback assigned to the switch release, if he trails through the crossing point without help he will lose leverage on the deep out breaking to the sideline. Against Cover 2, the curl route sits in the classic seam between the underneath zone defender and the deep half safety, so a user controlled linebacker sinking with depth can take this route away. Disguised zone blitzes or fire zone pressure can beat this play if the play-action fake does not sell, since the protection is built around the run look and will collapse against an extra rusher off the edge.
Sell the run fake by pairing this call after you have established HB Stretch or HB Power O from the same I Form Slot set so linebackers respect the play fake and step up.
Look for single high safety shells presnap since the switch release concept is designed to confuse man corners and create natural picks against Cover 3 and Cover 1.
Hot route the deep crosser into a shallow drag against Cover 2 if you need a faster underneath outlet versus a two deep shell that squeezes the curl window.
Use this on second and medium to second and long where defenses expect run action out of 21 personnel, since the play fake holds linebackers just long enough for the curl to sit open.
Sequence this with HB Toss or Jet Sweep earlier in the drive to bait aggressive run fits, then dial up PA Switch Curl to attack overpursuing linebackers and safeties creeping into the box.
