Playbooks
Buck Sweep out of Shotgun Wing Trips WK is a gap scheme run play that pulls the backside linemen (typically the guard and tackle) around the edge to lead block for the ball carrier, similar to a traditional sweep or GT concept. The frontside blockers execute down blocks and reach blocks to seal the edge while the pullers stack in front of the runner on the perimeter. The primary read progression is the runner reading the first puller to decide whether to bounce outside or cut it up through the alley created by the second puller, all while pressing the edge before making that final cut.
Key the play side outside linebacker and strong safety pre-snap, if either is stacked tight to the line of scrimmage in run support the sweep will get blown up before the pullers reach the edge. Watch for user-controlled defenders flying downhill off the snap, aggressive edge defenders who read pulling guards immediately can string this play out for a loss. Identify the coverage shell before the snap, single high safety looks with the strong safety cheating into the box are the biggest counter to this play, while two high shells that keep safeties out of the box give the sweep more room. Look for scrape exchange linebackers who trade gap responsibilities post-snap, since this defensive answer specifically targets gap schemes like Buck Sweep and can cut off the cutback lane. Diagnose blitz packages pre-snap, an overload blitz to the play side with extra defenders crashing the edge will beat the sweep to the perimeter and force a negative play.
Run Buck Sweep out of 11 personnel when you see light boxes or defenders cheating inside against inside zone tendencies, since the pulling linemen need room to get outside before defenders flow.
Use pre-snap motion or check the alignment of the strong safety and outside linebacker to the play side, since a fast flowing OLB or a safety sitting in the alley can blow this play up before the pullers get set.
Hot route the trips receivers into stalk blocks or quick outs if you expect an extra defender crashing the edge, this keeps the corner from squeezing the pullers.
Pair Buck Sweep with Power Read and PA Inverted Veer in this set to keep the defense guessing between gap schemes and read option looks, forcing linebackers to hesitate on their fits.
Best called on early downs (first and ten or second and short) when defenses are still base personnel and have not shown an overload blitz look, since Buck Sweep needs numbers on the perimeter to work.
