Dylanvir · The playbook room
RIVER.
Find the space.
One play. A changing defense.
Make a read, keep your reasoning, then see what changes when the defender responds differently.
Go deep. Make the corner account for downfield space.
Push upfield, then break out at an intermediate depth.
Move toward the sideline close to the line of scrimmage.

RIVER is an original Dylanvir teaching exercise. The drawings show chosen assignments, not film, tracking data or a simulation of an NFL outcome. The other defenders and protection must enter a fuller study before this becomes a complete play model.
For wider coaching context, Anthony Stone distinguishes pre-snap and post-snap reads; Clayton Cason’s report of Kyle Cogan’s coaching explains how route-matching responsibilities can change a simple zone picture.
