Packers or Cowboys?

That question isn't what you think, so let me explain. The stats say that teams with a first round bye are overwhelmingly favored to advance to the championship games of their respective conference. We also know that teams that are playing their best football going into the playoffs tend to keep their momentum going. So, given that the Cowboys have been playing less than stellar football and are banged up, and the Packers have been showing some weaknesses that culminated in a miserable game against the Bears, I think we are going to see an upset in the divisional round of the NFC playoffs. My question to you is, not knowing any pairings yet, which team is more likely to be upset, the Packers or the Cowboys?
