Not in any team playbook.
RPO Alert Bubble is run out of Shotgun Tight Y Off with 11 personnel and gives the quarterback a true run/pass alert based on the read defender. On the backside, the outside receiver runs an inside slant while the slot receiver runs a shallow bubble screen underneath, giving a quick horizontal outlet if the alert defender crashes down on the run. To the play side, the isolated receiver runs a corner route up the sideline as the vertical shot if the box count favors throwing. Up front, the offensive line executes an inside zone blocking scheme with the running back reading the alert defender off the edge, making this a true RPO that punishes overcommitted fronts and light boxes.
Identify the alert defender pre snap, usually the weak side end or outside linebacker, since his reaction determines whether the quarterback throws or hands it off. Watch for a slot cornerback or nickel sitting on the bubble screen, this eliminates the easy pass outlet and forces the run read. Look for single high shells like Cover 1 or Cover 3 which leave the corner route in a favorable one on one matchup against off coverage. Cover 2 shells with a hard flat defender crashing the bubble can jump the screen for a big hit or turnover if the quarterback throws to it without checking the flat defender's depth. Watch linebacker run fits post snap, if they crash hard downhill on inside zone with numbers advantage, take the automatic bubble read instead of forcing the ball into a crowded box.
Check the box count before the snap and let the alert defender dictate the read, if he sits inside hand it off, if he widens or crashes the run lane pull it for the bubble or corner. Use this in run heavy early down situations since the play disguises inside zone with a quick pass answer, making it low risk on second and short. Against single high safety looks with a cornerback playing off the corner receiver, take the corner shot for an explosive gain since the alert defender usually respects the run first. Pair this with RPO Zone Alert Bubble and RPO Peek Slant Bubble in the same set to keep the defense guessing on which route combo pairs with the run look. If the defense starts sitting on the bubble screen with a linebacker flying out, go back to the corner route or straight handoff to make them pay for over pursuing.
