Looking at this thing big picture, it's more about their record over four of their remaining games against Minn, Nawlins, Philly, and Seattle. If they don't go at least 2-2 in those four games vs playoff-level opponents they'll be a second tier team come playoff time.
So losing in Minnesota, if that happens, isn't the end of the world. All that aside though, yeah this is a huge game. And also of note is that Minnesota might be the least of that group of four teams, or below both Philly and Nawlins. Because both the Eagles and Saints not only play strong defense but also are explosive offensively.
