I believe Dallas is going to win just because I think they are the better team and through the last several years, their roster has been more consistent than the team that Snyder and co puts on the field. Danny just can't pass up that big name free agent signing that supposedly puts them over the top. Supposedly being the key word
Saying that, I aint going to worry until after Thanksgiving. Just like the last several years, I'm going to reserve judgement for the end of the year. Last year I was ecstatic because Dallas finally put together that strong end of the year run I had been waiting on, instead of the end of the year collapse I was used to seeing.
A few years ago...remember when the Patriots fielded their team in September that started with the surprise cut of their SS Lawyer Milloy. NE went to Buffalo the first game and got rolled 31-0... Nobody went into panic mode but the Pats only accumulated a 14-2 record, the last loss coming to a hungry upstart Steeler team that fell short in the playoffs to the same team. NE found the wherewithal to stay the course and whip their way to another Super Bowl victory.
It's all about finishing for me and not starting. But yes to the OP I agree that Dallas will win in DC.
