The most important thing on Saturday night is that the Dallas Cowboys beat the Detroit Lions. A win keeps Dallas alive in the NFC East and, thanks to what would be a victory over the Lions specifically, for the #2 seed in the conference. Given that Dallas is a much better team at home than on the road, the more games that they can play at AT&T stadium, especially if it is two that separates them from the conference championship game, the better.
But there are a number of things also on the line on Saturday night even if they are lower than an overall priority.
