This is the type of wrinkle that I don't know why we never use. In this play it's the QB, but is normally done with a TE. It's easy plug in, hard to defend, and could be added to any passing play.
QB walks up to the line (the TE would already be on the line) and the running back takes a direct snap.
QB is fake blocking (as a TE would) lol. The running back comes around for the pitch and eventual pass.
The QB sneaks into the second level due to the over-pursuit of the potential run.
The rest is history.
I don't know why we haven't incorporated this into our offense yet. Especially since we run so many RPO's.
