If the Packers lose at Minnesota and finish the season in a tie with New Orleans at 12-4 they would clinch the #2 seed if the Saints lose to the Panthers in week 17.
Yeah I know, that would be based on conference record. If they tie on conference record via losing one more game to an AFC team (which would now have to be @ Tennessee), I don't see the Packers having a way to win the SOV tiebreaker is what I'm saying.
