The Vikings game on Sunday against the Detroit Lions isn't so much must-win as can't-lose.
A loss would effectively end the competitive portion of a season and, perhaps, eradicate an entire organization.
Lose to the Lions on Sunday, and the Vikings will or should be on their way to a new general manager, coach, coaching staff and quarterback.
The Vikings are 1-3. A loss to the Lions would leave them 1-4 entering a difficult and perhaps season-defining six-game stretch against contenders.
If this sounds like too much emphasis on a game against woeful Detroit, please consider that the Lions' historic woefulness is exactly what makes this a vital game.
The Lions have lost eight in a row. The Vikings have won their past seven games against the Lions, with an average margin of victory of 12 points.
The Lions feature a new coach, Dan Campbell, who talked about biting opponents' kneecaps during his introductory news conference. Given Lions history, if Campbell spent every minute of every game on his hands and knees, trying to bite the legs of opponents as they ran by the Lions' sideline, that act would qualify him as one of the Lions' most effective coaches of the past 30 years.
The Lions are historically and persistently bad, and their mere existence has elevated the Vikings franchise. The Lions are the Purple People Feeders.
