It's quite possible that Monte Kiffin is still on the Dallas coaching staff because of Rod Marinelli's wishes and accepting or rejecting the defensive coordinator job. With that being said, if the Cowboys would've allowed Bill Callahan to go to Cleveland or Baltimore as the OC, I believe that Frank Pollack would have followed him. The Cowboys were more afraid of losing Pollack, and not so much Callahan. It's pretty apparent that the running game (when committed to) and the offensive line progressed in 2013, and I believe it was mainly because of Pollack. Thoughts?
