How would you rate Norm Chow as an offensive coordinator?

I know the common answer is to talk about how he has done with VY. As I've expressed in another post, Young is realistically not great. Our offense has looked like a division II team at times. We are horrible in the red zone. Take the JAX game for instance. I believe we took something like 12 or 13 snaps in the first half inside the 10 yard line, and didn't throw one ball into the endzone. Who does that? With VY's mobility one would believe that we could draw up some plays that would fool defenses, but we haven't seen that. Your thoughts.....

i think he did a good job attacking the defense horozonaly i would like to see more of it cornelius
