Breakdown

Seam Divide is a five man route concept out of Shotgun Bunch Wide that stresses the field both vertically and horizontally. From the bunch alignment, the outside receiver runs a deep corner, the middle bunch receiver splits the safety with a divide seam that turns into a deep post, and the third bunch man works an out route breaking to the boundary. Backside, the isolated receiver runs an under route to the flat while the running back releases on a deep crossing route toward the opposite sideline. This is a man beater built to attack single high and press man coverage, with the primary read progression starting at the seam divide route up the middle before working out to the corner and then the backside crosser as checkdown options.

Defensive Reads

Pre-snap, identify single high versus two high shells since this concept is designed to exploit the seam that opens in one high looks like Cover 1 and Cover 3. Watch the middle linebacker and free safety relationship at the snap. If the safety bails hard to the post side, the seam window tightens and the quarterback should work to the corner or out route instead. Key the flat defender on the backside crosser. If a user controlled defender jumps the crossing route early, the seam or corner route should be open on the opposite side. Look for disguised two high shells that roll to single high post snap since this can bait an inaccurate throw into the seam if the quarterback does not confirm coverage rotation. Cover 2 and Cover 4 shells with a deep middle safety sitting can shut this down by taking away the seam divide route, so be ready to check down to the flat or under route against those looks.

Usage Tips

Use this on obvious passing downs when you expect single high safety looks since the seam divide route splits the deep middle and creates a natural leverage advantage against Cover 3 or Cover 1.

Pre-snap, check the safety depth and count the defenders in the box. If you see two high safeties rotate down or bail late, hot route the seam runner to a post to attack the void.

Against man coverage, trust the seam divide receiver to win vertically off the free release from the bunch, especially if the defense shows blitz and the linebacker has to widen to cover the crossing back.

Pair this play with Curl Flat or Spacing from the same set to keep the defense guessing between shallow zone beaters and this vertical shot play, forcing the safety to respect both levels.

On third and long, use Seam Divide as a shot play but keep the outside out route and backside crosser in mind as safety valves if the initial seam window closes under pressure.
