As for who would win each tiebreaker based on each possible scenario, remember: Who owns tiebreakers can EASILY change based on results of games to come, especially if those tiebreakers don't involve head-to-head play - ESPECIALLY if it is a multi-team tiebreaker, so take any "they own the tiebreaker" statements with much more than a grain of salt.
Those tiebreakers will be even more complicated based on the games to come - many head-to-head against other contenders:
Seattle (8-4, Packers would win head-to-head tiebreaker)
- 12/10: at Jacksonville
- 12/17: vs. Los Angeles Rams
- 12/24: at Dallas
- 12/31: vs. Arizona
Atlanta (7-5, would win head-to-head tiebreaker over Packers)
- 12/7: vs. New Orleans
- 12/18: at Tampa Bay
- 12/24: at New Orleans
- 12/31: vs. Carolina
Dallas (6-6, Packers would win head-to-head tiebreaker)
- 12/10: at New York Giants
- 12/17: at Oakland
- 12/24: vs. Seattle
- 12/31: at Philadelphia
Detroit (6-6, head-to-head tiebreaker would be tied if Packers win rematch; Detroit leads now)
- 12/10: at Tampa Bay
- 12/16: vs. Chicago
- 12/24: at Cincinnati
- 12/31: vs. Green Bay
Among other teams in the hunt, New Orleans (8-4) leads Carolina (8-4) by a tiebreaker. The Saints would win a head-to-head tiebreaker with the Packers, so it would be advantageous for the Saints to win the South and have Carolina be the wildcard contender between them. The Packers would win a head-to-head tiebreaker against Carolina if they beat the Panthers on Dec. 17.
Don't worry. Those tiebreakers will play themselves out.
