It is always difficult to take away too many things from the first game of an NFL season, because some teams come in playing at or near their mid-season form, while others are essentially playing a preseason game and still figuring things out. The Dallas Cowboys looked a lot more like the latter in week one, while their opponent, the Carolina Panthers, were much closer to the former. While that means it is hard to learn a lot about the teams in that opening contest, for the Cowboys, one lesson seems clear: Preseason is important for some players and positions, and Dallas did not get enough done this year.
