New Orleans Saints: Final seeding probability going into Week 17

What is the possibility the New Orleans Saints get the No. 2 seed?
The top two seeds if they playoffs began right now would be the Green Bay Packers and the San Francisco 49ers. They are both tied with the New Orleans Saints at 12-3, but they have the more divisional wins so they are the higher seeds.
They will remain the higher seeds with wins by both of them. The first thing that has to happen for the Saints to have a shot at this seed is they have to win against the Carolina Panthers. That task is not looking too hard the way the Panthers have played lately.
They will also need one of the two to lose in week 17.
San Francisco will go on the road to the Seattle Seahawks for a divisional finale between two 10 win teams. In their first meeting of the season, the Seahawks got the best of the 49ers in OT 27-24. The ESPN Power Index gives the 49ers the win with a 56.3%. This is anyone’s game.
The Green Bay Packers will go on the road as well to the 3-11-1 Detroit Lions. This game will most likely be a high-scoring, one-sided game. The ESPN Power Index gives the Green Bay Packers a 69.7% chance to win this game.
Probability of ending with the No. 2 seed: 47%
