It is what it is. The Cowboys are not real contenders.
And all four of those losses are on the road, where it is tough to win against teams that are your equal. On the road, Philadelphia has lost to us and Seattle and edged Kansas City. Their other games against contenders (Buffalo and Miami) have been at home, except San Fran, while we've only played Philly and Seattle at home. Detroit will be a good test of that theory.
However, it doesn't matter, unless Philly loses to the Giants or Cardinals while we don't lose any more games, our path through the playoffs is on the road. And ultimately, we'd probably have to go to San Fran anyway.
