Quick perimeter screen to a slot receiver retreating behind the line of scrimmage.

The design

How Bubble Screen works

Standalone quick screen to a slot receiver.
The target releases backward and outside on the canonical Bubble banana arc, catches 0-3 yards behind the line of scrimmage, and immediately turns up the sideline.
The nearest outside receiver occupies or stalks the corner while backside receivers clear coverage.
Unlike Bubble RPO, this is a called pass with no run read or handoff option.

Call sheet

PressureCall it when the defense gives the slot a numbers or leverage advantage, especially against pressure or a soft apex defender.
Defensive lookThe ball should be out immediately so the receiver catches with space and blockers in front.
Defensive lookUse fast motion or a stack to uncover the bubble against press.
Game planIn no-block flag rules, have the outside receiver occupy the corner with a short hitch instead of modeling an illegal stalk block.
Game plan

On a compressed field, shorten the receiver split so the bubble still has room to arc outside.

Cover 0: Anything that develops slowly — pressure gets home first Better answers: Four Verticals, Mesh, Slant-Flat, Smash
Cover 1: Outside vertical shots — the free safety caps them over the top Better answers: Mesh, Drive, Smash, Y-Cross, Four Verticals, Levels
Cover 2: The flats — the corner squats and jumps anything quick outside Better answers: Smash, Four Verticals, Flood
Tampa 2: The deep middle — the Mike runs it, so a straight seam is contested (unlike base Cover 2) Better answers: Smash, Flood
Cover 3: Deep outside — the three-deep shell caps outside verticals Better answers: Curl-Flat, Slant-Flat, Smash, Flood, Four Verticals, Snag, Dagger, Stick
Cover 4: Deep shots — four deep defenders make it very hard to win over the top Better answers: Stick, Snag, Slant-Flat, Curl-Flat, Mesh

Troubleshooting

Avoid it against press leverage that can collision the bubble target or when the defense has more perimeter defenders than available receivers.
It is a quick numbers throw, not a slow-developing route concept.
The receiver runs forward before widening; the bubble must retreat first so the throw stays clean behind the line.
The quarterback holds the ball instead of catching and throwing immediately.
The outside receiver releases vertically without accounting for the corner, leaving the bubble target one-on-one at the catch point.
