I believe Calgary has a better chance of making it,
After D. Sutter got fired in Calgary the Flames went on a 17-3-2 run all the way to March. Achieving the most points out of any other NHL team from January - March. If they continue that trend look for them to get 4th this upcoming season.
As for the Wild, they lost Brent Burns, HUGE loss for the team IMO, he has great upside.
