Thinking about this a lot more, I'm thinking the Cowboys have the best counter to many of the top NFC teams. The Cowboys, at least how they've shown this game, are able to just grind the time of possession game to 1) Make up for their weaker defense and 2) Keep the stronger high powered offenses like Atlanta, Green Bay, etc off the field.
I hate to say it because I dislike the Cowboys, but I can honestly see them going deep into the playoffs because this running game/time of possession game is a big deal
