Playbooks

HB Ace Power is a gap scheme power run out of Singleback Bunch 11 personnel, with the bunch alignment stacking receivers to one side to influence numbers at the second level. The play pulls a blocker across the formation to lead through the hole while the offensive line down blocks to create a wall, sending the HB on a downhill path off the pulling guard's track. This is a straightforward power run play, not a play-action or RPO, so the primary read is the running back keying the pulling lineman's landmark and pressing the hole before deciding to bounce outside or cut back based on how the frontside defenders react.
Watch linebacker depth before the snap, since stacked or blitzing linebackers will crash the pulling blocker's path and blow up the power lane before it develops. Key the play side defensive end and outside linebacker leverage, if they squeeze hard inside the lead blocker can still turn it up for a cutback. Against a nine or eight man box, this run gets sold out immediately, so recognize overloaded fronts and be ready to bail into a different call. User linebackers who sit and read the mesh point rather than flowing with the play fake out patient ball carriers and are the biggest threat to gap scheme runs like this. Bunch formations often trigger a defensive shift or safety rotation toward the stack, so check if the backside is left thin enough to negate the run fit entirely.
Check the box count before the snap and only run this into light boxes with six or fewer defenders in the tackle box since power concepts get gang tackled against stacked fronts.
Identify if the defense shifts toward the bunch formation, since that alignment often pulls linebackers and safeties out of position and opens the backside cutback lane.
Use manual control on the fullback or lead blocker to seal the edge defender rather than trusting the CPU logic, especially against user defenders flowing hard downhill.
Pair this with HB Slam or Duo out of the same Bunch look to keep the defense guessing between gap schemes and force linebackers to hesitate on their run fits.
Save this play for early down situations like first and ten or second and short, since the deliberate blocking setup needs time to develop and gets blown up on predictable third and short calls.
