Speaking of seeding, I've been dicking around with a playoff simulator and the #2 NFC seed is almost certainly going to come down to who wins the Green Bay @ Arizona game in two weeks.
If Arizona wins, that game alone clinches the division and #2 seed and Philly and Seattle games don't matter (except to possibly knock Seattle out of a wild card spot)
If Green Bay wins that game the #2 seed is theirs, unless Arizona beats Philly AND Seattle, or unless Minnesota wins out and takes the division (Arizona and Minnesota would have the same record in this scenario but Arizona has the tiebreaker). In every scenario where Minnesota and Green Bay finish with the same record, the division goes to who wins their game in week 17.
