In your dreams... The Cowboys didn't win on their own merit. Eli dip shit gave the game to them... and me thinks the Cowboys aren't gonna be as strong as you think this year. The Jets will surprise many.
Putting stock in the first games of the season is usually a waste of time, the last ones are the most important and are the best indicator of the team as a whole. I've seen teams start 6-0 and end up 8- 8 if not worse.
