Imagine what kind of pressure it would put on the defense if the Cardinals ran RPOs (run/pass options) with David Johnson (and Chase Edmonds when he’s in the game). On a key third down, Josh Rosen could run with the ball to move the chains (on a slide) if the end crashes down...but most of all, Rosen can fake the handoff and then pass into the open areas behind the linebackers. The Vikings and Eagles did this very well last year with Keenum and Wentz/Foles.
Why have a FB on the roster and not use him?
So—-OC Mike McCoy is not keeping the LBers honest with RPOs—-he isn’t even running head-on iso blocks with a FG on them.
