I've heard that's the plan. They will try to work the schedule so as to have the Vikings play as few late-season contests at TCF as possible.
Kind of a two-edged sword though especially if they're in position to make a late playoff push but wind up having to play a lot of those games on the road. And honestly, I don't see why the Vikings should get any more help avoiding cold weather games than teams like the Packers, Bears, Steelers, Pats or Bills get. For those 2 years they are going to be an "outdoor" team whether they like it or not.
