True, in theory. But in that scenario, I believe conference record would be the tiebreaker and we'd be 4-4, Seattle would be 4-4 but Atlanta and Detroit would have been conference records.
If the Vikings beat Detroit, Detroits conf. record would be 4-4 as well. Atlanta is a problem though. They seem to hold all the tie breakers. They have head-to-head over Det, Dal, and Seattle. Their conf. record is also 5-1 right now. Their schedule is pretty brutal though. They have NO twice, Min, and they finish against Carolina...which might actually be a game we want them to win, depending on how things go the next few weeks. Carolina still also has NO and Min (and I am not counting out a Jets surprise this weekend).
This is what I meant by these teams play each other still, and some twice.
Vikings have Lions, Falcons, Panthers, GB, Bears, and Bengals too. So actually we need to root for them to beat the 3 teams we competing with on that list. And also get ahead of the Eagles, as not to have the Eagles having HF advantage.
Panthers, if they drop some games too would help, to Vikings, GB, NO, even get upset by Jets and TB. Then they and Falcons play the last game of the season.
There are quite a few scenarios like this giving teams losses that we are competing with.
