Is it possible that when Kelly runs, he's consciously giving not so much deemphasizing the passing game, but keeping in check his desire to put up gaudy offensive numbers. I.e., its not so much his not being stubborn as it is putting his ego off to one side. Remember the story of what he said to Collaros in the 2nd half of a big Cincy upset, something along the lines of "...remember, I'm in control here, I could have you put up more points if I wanted...'.
Regardless, he's a damn fool if he can't do a simple compare and contrast on the types of results he gets when he commits to a balanced offense. Our run game is there.
