HB Stretch Alert Bubble is an outside zone run out of Singleback Doubles with an alert audible built in for the slot receiver. The offensive line flows laterally to the play side executing zone steps and combo blocks to seal the edge, while the running back reads the stretch flow and presses the line before cutting upfield off his blockers' leverage. The alert tag turns the backside slot receiver's route into a bubble screen, giving the quarterback a pre-snap or post-snap outlet against overloaded fronts, making this a run play with a built-in RPO style bubble alert rather than a straight dropback pass.
Read the defensive line's gap alignment pre-snap, a heavy shade towards the play side signals the defense is selling out to stop the stretch run. Check the slot corner or nickel defender's depth and leverage, if he is playing tight man coverage with inside leverage, the bubble alert is a bad matchup and you should stick with the run. Watch for backside linebackers flowing hard to the play side post-snap, overpursuit here opens up the cutback lane for the running back. This play struggles against disciplined zone defenses that keep a linebacker sitting in the flat area, since that defender can jump the bubble route immediately. Beware of run blitzes from the play side edge, if a defender is crashing down pre-snap with no regard for outside contain, consider bouncing the run wider or checking to the bubble for a quick answer.
Use pre-snap to identify if the defense is stacking the box or bringing extra defenders towards the run side, since that is your trigger to throw the bubble alert instead of handing it off.
If the slot corner or nickel defender is playing off coverage with soft leverage, the bubble screen is nearly automatic for a easy five to seven yard gain.
Run this on early downs like first and second down to keep defenses honest and force linebackers to respect both the stretch run and the quick bubble read.
Pair this play with HB Stretch, Jet Sweep, and PA Stretch in your play-calling sequence so the defense cannot key on run tendencies from formation alone.
Motion the slot receiver pre-snap to check numbers on the perimeter, if you get a numbers advantage outside, take the bubble immediately off the snap.
