And for the same reasons.
The Vikings are battling Green Bay for the division, while the Cowboys are battling Philadelphia.
But the prize in this contest is "confidence", with each team needing to know they are for real.
Minnesota has been very good, but the games they have lost led to speculation that nearly derailed their season about the quality of Kirk Cousins as their quarterback.
The Cowboys are still hoping they are one of the league's best, and they need to KNOW this heading into the toughest stretch of the season.
Sunday night will be a tell-tale sign to each club; and the repercussions of losing could very easily destroy the season for whomever fails, as doubts begin to creep in and the futures of coaches and players on the bubble begin to be decided.
Not to mention the respective division battles of each club.
