Here's a cool simulator you can play around with.

Trying to pick realistic outcomes it boils down to this if the Vikings can go 2-1 down the stretch with their only loss being to the Packers.
They need the Saints to lose one, and they have a pretty easy schedule ahead.
They need the Rams to lose tonight, and then the Vikings obviously need to beat them next week. The Rams then have two games left, at Baltimore and at home against the 49ers, and both are not an easy feat. The Rams would have to lose out if the Saints win out. If the Rams win tonight, this scenario is eliminated.
The easiest path is the Vikings going 2-1 and the Saints just have to lose 1 of their last 3, and the Vikings are in. The Vikings could still make it if they only win 1 more game and the Saints drop 2.
The Saints beating the Bucs was very bad for the Vikings on Sunday.
