Romo's QB rating for the season is 78.8. But his QB rating for the season when throwing a play action pass is 135.4. That's a huge difference.
Call more play action pass. That's one way of having your QB play better.
But in order for the play action to work well, we have to run better. Bottom line is, we run better, Romo can pass better if our OC knows what he is doing.
