I was watching a video, can't remember where, where the analysts were discussing the state of the Dallas Cowboys. They were saying that the offense was the big question mark going into the season. They talked about how the offensive line is weak and who was going to be the 3rd receiver as well as could Dez and Miles stay healthy. They also questioned the running backs and their ability to stay on the field. I alway thought the offense was overall in pretty good shape and the defense was much more of a concern. I know we have question marks on the Oline but the D is what let us down last year. Which side of the ball needs the most improvement? I say the defensive side.
