Before kickoff on Sunday afternoon, there were still a lot of looming questions surrounding the Dallas Cowboys defense. Hopes were high that Mike Zimmer would be able to improve this defense, but it was hard to be confident how everything would play out in just the first game of the season. Although it is only one game, the defense took the opportunity to clear the muddy waters and show the world that they were more than ready. Hopefully it is just a glimpse of what else is to come this season.
