The Vikings not only have a decimated offensive line, but they don't have a QB identity either. McCarthy's injury hurts, and now the injury to Wentz. They're snake bit.
The Packers learned years ago that you need to use players who can effectively play multiple positions on the line effectively if you want to maintain some sort of strength going forward. The Vikings haven't got that luxury at this point. I don't doubt that those injuries have led to their QBs taking some hits that might not have been nearly as severe with a line that wasn't hurting.
If they do heal and get their team on a level keel, they could be in the playoffs Being 3-4 at this point doesn't eliminate them from anything.
As far as coaching, they have a pretty good staff.
My problem is, I don't like the Vikings and hope they flop but at the same time, I believe the words "credit where credit is due" goes above my personal feelings about them. They are "not" a rivalry to the Packers. They're the snot nose kids who came to the party late, shoot their mouths off about how good they are, and never deliver on their promises.
