offense / gap run
A downhill gap run that uses a pulling guard to create an extra blocker at the point of attack.
Animated assignment view
The quarterback confirms the play-side linebacker and the tight end identifies the force defender.
Ball: center
How it works
Play-side blockers collapse defenders inward while the backside guard pulls across the formation. The puller handles the force player and the back follows his leverage into a deliberately created gap.
Outnumber the defense at one chosen gap and give the runner a clear physical entry point.
Stay tight to the puller's block and get vertical.
One guard runs behind the line and leads the runner through a new opening while the other blockers push defenders away from that spot.
The puller's kick-versus-log decision changes the runner's path; spacing between the down blocks and puller must not create a run-through lane.
Decision point
The puller's leverage determines whether the runner stays inside, follows around, or bends away from congestion.
Hit the crease inside when the guard logs the force defender outward.
low riskStay on the puller's outside hip when he kicks the defender inward.
medium riskCut behind the down blocks if the front overfills the designed gap.
