Breakdown

FB Flare out of I Form Slot 21 personnel shows the fullback releasing out of the backfield to the flat while the HB runs a check release into a flare route underneath. On the backside, two receivers stack a vertical release with an out and up combo, and the far outside receiver runs a deep vertical to stretch the defense downfield. This is a play-action style pass concept with man beater traits built in, since the FB and HB flare routes create immediate leverage against man defenders who follow their backfield assignments. The primary read progression starts with the FB flare in the flat, checks down to the HB flare underneath, then works vertical to the deep routes if the underneath options are covered or if a blitz is picked up cleanly.

Defensive Reads

Pre-snap, identify if the defense is in a two high shell or single high shell, since a two high look with soft corners invites the quick flare throw to the FB. Watch linebacker depth at the snap, since shallow linebackers who flow hard to the run will get beat by the FB flare release into the open flat. If you are on defense, spy or shadow the fullback with a linebacker who has flare responsibility to eliminate the easy checkdown and force the quarterback to hold the ball longer. Man coverage with no underneath help is vulnerable to both backfield releases, so user a linebacker to jump the FB flare route if you anticipate this concept based on formation tendency. Cover 3 or Cover 4 zone shells with deep safety help can shut down the vertical routes, forcing the quarterback into the flare checkdowns, so squeeze the flat defenders to take away that easy completion as well.

Usage Tips

Use pre-snap motion or a quick glance at the box count to confirm if the defense is selling run, since the I Form alignment with 21 personnel often draws run blitzes that this pass concept can exploit.

Hot route the FB flare to a flat route or drag if you are facing a Cover 2 shell, since the flare naturally sits in the same landmark as a Cover 2 corner's zone.

Target the FB flare quickly against man coverage when a linebacker is matched up, since fullbacks typically win the footrace to the flat against slower defenders.

Pair this play with HB Dive Alert Bubble or HB Blast earlier in a drive to condition the defense to expect inside run action, then hit the FB Flare off similar formation tendencies to catch defenders flat footed.

Use this on early downs or third and short to keep the defense honest, since the quick flare read allows you to throw with anticipation before pressure arrives.
