Breakdown

Mtn RPO Alert Swing is a run pass option out of Shotgun Y Off Trio Close that pairs an inside zone run look with a swing route out of the backfield. The diagram shows the offensive line blocking down for zone run action while the halfback motions out and swings wide to the flat, giving the quarterback a pre-snap alert read on the perimeter defender. The yellow arrow shows the give read into the mesh point, meaning the primary progression is handoff first, swing route second if the flat defender bites down on the run fit.

Defensive Reads

Key the play side linebacker and flat defender immediately after the snap, since their reaction to the run action determines the correct give or throw decision. Against man coverage, look for the defender assigned to the halfback to trail him through the swing motion, which signals the quarterback to hand the ball off instead of throwing outside. Against zone coverage, especially Cover 3 or Cover 4 shells, watch the curl-flat defender's depth, since a defender sitting too far inside opens up the swing throw to the flat. Blitz-heavy defenses that crash extra defenders into the box create explosive run lanes, but if the defense shows a nano blitz off the edge, get the ball out quickly on the swing before contain collapses. Be wary of user-controlled defenders lurking in the shallow flat, since a heads-up human defender can jump the swing route and turn it into a pick-six if the quarterback locks onto the alert read too early.

Usage Tips

Use pre-snap motion on the halfback to identify if the defense is playing man or zone based on whether a defender follows across the formation.

This play works best against light boxes with six or fewer defenders in the run fit, since the RPO read punishes overaggressive linebackers crashing downhill.

If the flat or curl defender widens with the swing motion, pull the ball and throw the swing quickly before the edge defender can recover.

Pair this play with Mtn Inside Zone and Mtn Same Side Zone in the same set to condition the defense to sell run fits, then hit them with this RPO once they start cheating linebackers into the box.

On third and short or second and manageable, this is a great called-run alternative that still gives you an answer if the defense stacks the box.
