Reunite norv turner with ron rivera and u become effective on both sides of the ball.
That may not even work. I wonder if more of your o issues lie with running the Coryell. I used to be a huge proponent, but in the last 2 years I've changed my tune watching PR run McCoys O (Erhardt-Perkins with ZBS).
I know your OL talent is much better suited for that since plays don't need to develop like the Coryell plays do. It's just the question of whether the WRs can get earlier separation and Cam can make the right reads/throws.
