Well, we made it through another tiebreaker season.  Thanks to all for your participation, well-thought out comments and feedback.   Atlanta losing on Monday night certainly made for an interesting group of scenarios for the #1 seed in the NFC, but Philadelphia laying an egg on Tuesday night simplified many things in the NFC.   Full scenarios are listed below.

NOTES:
- ATL will be #1 seed UNLESS they lose and either NO or CHI wins
- ATL will be #2 seed if they lose and NO loses and CHI wins
- ATL will be #5 seed if they lose and both NO and CHI win
- NO can only be a #1 or #5 seed and will be #1 if they win and ATL loses
- If NO not #1 seed, they will be #5 and play AT NFC West winner (STL or SEA) Wild Card weekend (Saints beat both teams this year at home)
- CHI is the #2 seed unless ATL and NO both lose and CHI wins...then CHI would be #1 seed
- PHI is the #3 seed and will host the #6 seed (either GB, NYG or TB) on Wild Card weekend
- The STL-SEA winner (or STL in case of a tie) will host ATL or NO (whichever doesn't win the South) on Wild Card weekend
- GB will know by game time if their opponent (CHI) is locked into #2 seed (CHI would need ATL and NO losses in 1pm ET games to have chance at #1 seed).
- If GB wins, they will play at PHI on Wild Card weekend as the #6 seed.
- If TB wins early, GB knows they will need to win to get into playoffs and TB will root for GB and NYG losses to get a trip to PHI.
- TB game only matters to NYG if the Giants tie WAS.
- NYG can only get in as #6 seed and would play at PHI for a third game this season against the Eagles with a WIN and GB loss
- If TB, GB and NYG all win or all lose, GB will play at PHI on Wild Card weekend based on GB winning strength of victory tiebreaker among the three teams at 10-6 or 9-7.   At 10-6, GB would have a minimum wins by defeated opponents of 74 while NYG and TB would have maximums of 65 and 59 wins respectively.  At 9-7, GB would have a minimum wins by defeated opponents of 63 while NYG and TB would have maximum of 61 and 49 wins respectively.

Atlanta wins SOV tiebreaker unless NYG, SF, IND, and PIT all win; if all four win, Philadelphia ties Atlanta on SOV and, since Chicago drops out of tiebreaker, scenario reverts to Step 1 of two-way tiebreaker and Philadelphia wins over Atlanta based on head-to-head victory.]

----------

NOTE: The WORST CASE SCENARIO for PIT in the strength of victory (SOV) tiebreaker with BAL referenced above is a TIE.  That means, to clinch SOV this week over BAL, PIT only needs ONE of the following to occur:
- CIN win/tie over CLE
- ATL win/tie over SEA
- TEN win/tie over HOU
- OAK win/tie over DEN
- ARI win/tie over CAR

Will post PIT/JAC SOV scenario in comments below.
