ESPN Insider analysis Joe Theismann on Dallas Cowboys

This is from his ESPN Insider analysis of the NFC East: Dallas Cowboys

So far this season, the Cowboys have shown they are one of the better teams in the league some weeks and one of the more mediocre teams in other weeks. It's interesting to see that from a Bill Parcells team, especially one he has put his stamp on pretty hard. This team has to start playing more consistently because it's extremely important for Dallas to start winning the games it has in hand. The Cowboys can't afford to cough up a game the way they did against the Seattle Seahawks earlier this season.The Cowboys have a strong team offensively and defensively and could very well be the best team in the division. They simply must become more consistent or they won't be the team some believed would win this division.
