The only way Atlanta gets in is a three way tie in record of the vikings, seattle and atlanta. In that case head to head goes out the window because all three teams haven't played each other as atlanta did not play seattle. It actually gets down to strength of schedule which is 4th or 5th on the list (basically how many victories do the teams have that you beat) and the vikings would come out third on that.

It's very slim, but possible. The vikings and seattle would have to loose out and atlanta would have to win out.
