Vikings (6-4) at Bears (7-3)
Oddly enough, the Vikings really don't concern me.. though they do have the same record as us, we have the H2H tie-break over them. I think in this case, we treat the Vikings like the Packers. A buffer zone is better in the long run than beating the Bears and creating a 3-way tie for the NFC North lead if the Giants also defeat the Packers. Go Bears in this case.
This is the only one where I disagree with you. The Vikings' remaining schedule is the Bears twice, Packers twice, at Houston, and at St. Louis. They should be dogs in every one of those games and IMO will be lucky to get to 8-8. I'd rather the Bears lose because they're much more likely to be fighting for a spot with us at the end of the season.
In the NFC North the Vikes and Lions have the toughest schedules. The Bears schedule isn't a cake walk either. They have the VIkes twice, Seattle, GB, Zona and the Lions. As of right now though they do pose the biggest threat for the Wildcard since GB will most likely take the division with their easier schedule. I still think the Hawks have a legit chance to take the NFC West.
