Breakdown

RPO Alert Bubble is a run pass option out of Shotgun U Off Trips that pairs an inside handoff look with a bubble screen to the slot receiver. The diagram shows the slot receiver sitting down into a bubble route behind the line while the outside receiver in the trips bunch runs a shallow crossing route underneath to occupy flat defenders. The QB reads the alley defender or flat defender: if that defender crashes to stop the run, pull and throw the bubble, and if he sits or widens to the bubble, hand the ball off on the inside run scheme.

Defensive Reads

Watch the alley defender or nickel/linebacker aligned over the trips bunch before the snap, his run fit dictates whether the bubble or the run is live. Cover 3 and Cover 1 with an aggressive flat defender crashing downhill get gashed on the run side of this RPO. Zone defenses that widen a linebacker to the bubble receiver at the snap take away the quick throw and force the QB to hand it off into a lighter box. Man coverage with a corner locked on the crossing route can create a rub if the defense blitzes off the edge, so track for a user spy or contain defender crashing the mesh point. Disciplined defenders who stay square and read the mesh point without committing early neutralize both options and force a checkdown or a stuffed run.

Usage Tips

Check the alignment of the defender over the bubble receiver before the snap, if he is playing off or shaded outside the run is live.

Use the flick or hot route to adjust the bubble receiver into a quick screen against teams that walk a corner down into the box.

This play shines on early downs (first and ten or second and short) where defenses commit extra bodies into the box to stop the run.

Pair this with Read Option or Inside Zone from the same set so defenses cannot key on the bubble action without opening up the interior run game.

Snap the ball quickly against aggressive user blitzers, since holding the snap count lets defenders diagnose the RPO and squeeze both the run lane and the bubble throwing lane.
