As an example, look at what Denver did last year. Awful Manning who threw tons of picks with an awful offense. They won the Super Bowl on Defense. The Vikings won't be quite as good as Denver, but their offense should be better anyways, with all of those receivers and AP to boot. The Vikings will be fine. People like to call everything "the worst thing ever" or "the best thing ever". The Vikings have an easy schedule too. Just look at it!
Titans, Packers, Panthers, Giants, Texans, Eagles, Bears, Lions, Redskins, Cardinals, Lions, Cowboys, Jaguars, Colts, Packers, Bears
Assume the Vikings lose both games to the Packers. They still win tons of games here. Totally soft schedule.
