Go's Y-Under is a five man route concept out of Shotgun Spread Y-Slot that stretches the field vertically while working an under route across the middle as the underneath answer. The two outside receivers run go routes straight up the numbers to take the top off the coverage, the slot runs a quick out to the boundary, and the Y (tight end) runs the under route from the backside across the formation into the shallow middle, crossing under the go route traffic while the running back releases into a flat route underneath. This is a man beater with built in zone answers: against man coverage the go routes isolate corners on deep shots, and against zone the Y-Under gives the quarterback a rhythm throw sitting down in the void underneath linebackers. The primary read progression starts with the two go routes for an explosive shot play, then works down to the Y-Under crossing the field, with the flat route from the running back as the checkdown.
Identify two high safety shells pre-snap, this tells you the go routes are covered and the Y-Under crossing route into the void is your primary answer instead. Watch linebacker depth at the snap, if the middle linebacker sinks deep to cover the under route the flat route from the running back becomes open for an easy checkdown. Key the boundary corner's technique pre-snap, if he is playing off man or soft zone the go route to that side is a low risk deep shot with room to work back to the ball. This concept struggles against zone coverages with a robber or lurk defender sitting in the shallow middle since that user controlled defender can jump the Y-Under route and bait the quarterback into a turnover. Watch for disguised blitzes off the edge, since both outside receivers are running vertical routes there is no immediate hot route help outside and a fast rush can collapse the pocket before the go routes clear coverage.
Use pre-snap motion or a quick glance at safety depth to decide if the go routes are live, if both safeties are deep at 10 plus yards this is not your shot play so plan to work the under route instead.
Against single high looks with the corners playing tight man, put your eyes on the boundary go route first since it isolates the corner with no safety help over the top.
Hot route the running back to a check release or stay in protection versus known blitz down and distances since the flat route is your last progression and you need extra time for the go routes to develop.
Pair this play with 45 Quick Base or Bubble Screens in your play calling sequence to keep defenses honest on quick throws before coming back to Go's Y-Under for the deep shot once the defense starts jumping short routes.
Best used on early downs or in shot play situations like second and long, avoid calling this on third and short since the go routes take too long to develop for a conversion throw.
