The Vikings will make the playoffs if:
This week:
1. The Vikings beat Green Bay today.
2. Washington loses in Chicago this week (or against the Giants next week).
3. Tampa Bay loses at New Orleans.
Keep in mind:
If Detroit wins at Dallas on Monday, the Lions clinch the NFC North and the three-way tie scenario next week becomes moot. If Detroit loses, there's an added layer for the Vikings.)
Next week:
1. The Vikings beat Chicago on New Year's Day.
