Duo diagram and notes#
Family: Gap/vertical run
What it is: A downhill double-team run that looks like inside zone but behaves more like power without a puller. The back presses inside and reads linebacker movement.
When to use it: When the offense wants vertical displacement without exposing a pulling guard.
Good against: Odd fronts, light boxes, two-high structures, and defenses that spill power well.
Bad against: Heavy interior movement, slants into the double teams, and linebackers who beat blockers to their fits.
Pairs well with: Pairs with play-action glance, stick RPO, and tight end pop.
