The success of the cowboys will mostly be dependent on two things moving forward. Getting Collins/Smith back and for them to remain healthy. If the OL plays well that sets the table for the the cowboys and their prolific weapons to score alot of points. Secondly the DL has to not only get consistent pressure on the QB but also can't be porous against the run. The pressure on the QB will give much needed help to our suspect secondary. Diggs I think will be a stud but the others have not looked good. Nolan's schemes may be a factor hard to tell how much, but the secondary is getting burned way too often.
