Maybe this will help with deciding who to play tomorrow.....from Fox sports.
NFC Scenarios

Atlanta (12-3)


Best-case scenario: Atlanta secures the No. 1 seed and home-field advantage throughout the playoffs with a home victory over lowly Carolina (2-13).
Worst-case scenario: Atlanta drops to a wild-card spot with a loss to the Panthers and New Orleans victory over visiting Tampa Bay.

Chicago (11-4)
Best-case scenario: The Bears win at Green Bay, Atlanta gets upset by Carolina and New Orleans loses to Tampa Bay. That would give Chicago the No. 1 seed over the Falcons because of a better winning percentage against common opponents. The Bears would be 4-1 (.800 winning percentage) in games against Green Bay, Seattle, Carolina and Philadelphia; Atlanta is 3-1 (.750) vs. those same foes.
Worst-case scenario: New Orleans wins, Atlanta loses and Chicago falls to the Packers. That would give the Saints the No. 1 seed.

Philadelphia (10-5)
Best-case scenario: Because of the Vikings loss, Philadelphia is locked into the No. 3 seed win or lose Sunday against Dallas.
Worst-case scenario: None.

New Orleans (11-4)
Best-case scenario: New Orleans takes the NFC South with a win over Tampa Bay and an Atlanta loss to Carolina. That would assure the Saints of at least the No. 2 playoff seed. New Orleans could then claim the No. 1 seed if Chicago lost at Green Bay.
Worst-case scenario: Atlanta wins. That would automatically relegate New Orleans to the No. 5 seed.

St. Louis (7-8)
Best-case scenario: A win Sunday night at Seattle gives the Rams the NFC West crown.
Worst-case scenario: The Rams are eliminated with a Seahawks victory.

Seattle (6-9)
Best-case scenario: Backup quarterback Charlie Whitehurst steps up and the Seahawks become the first division winner in NFL history with a losing record by topping visiting St. Louis.
Worst-case scenario: The Seahawks lose their fourth straight game and sixth in their past seven to end Pete Carroll’s first season as head coach on a down note.

AFC Scenarios

New England (13-2)
Best-case scenario: The Patriots already have achieved it by clinching home-field advantage throughout the postseason.
Worst-case scenario: New England loses a player to injury in Sunday's meaningless season-finale against visiting Miami. The Patriots already had qualified for the postseason in 2009 but tried to secure the No. 3 seed by playing starters in Week 17 against Houston. Wide receiver Wes Welker tore two knee ligaments in the first quarter and was lost for the playoffs. The Patriots then lost at home the following week to Baltimore.
Pittsburgh (11-4)
Best-case scenario: A victory Sunday against slumping Cleveland would secure the AFC North title and the No. 2 seed that brings a bye week.
Worst-case scenario: The Steelers lose to Cleveland, Baltimore defeats Cincinnati and the New York Jets top Buffalo. The Ravens would win the AFC North and Pittsburgh would fall to the No. 6 seed behind the Jets because of New York's 22-17 victory at Heinz Field in Week 15.

Kansas City (10-5)
Best-case scenario: Defeating visiting Oakland would clinch the No. 3 playoff seed.

Worst-case scenario: The Raiders win and Indianapolis defeats Tennessee at home. That would drop Kansas City to the No. 4 seed because of the Colts having defeated the Chiefs 19-9 in Week 5.

Baltimore (11-4)
Best-case scenario: The Ravens defeat Cincinnati and Pittsburgh loses to Cleveland. That would give Baltimore the No. 2 seed.
Worst-case scenario: The Ravens lose or Pittsburgh wins. If the Ravens and Steelers both finish with the same record, Pittsburgh gets the tiebreaker nod because of a better division record (5-1 to 4-2).

New York Jets (10-5)
Best-case scenario: The combination of a Jets win over Buffalo and either Pittsburgh or Baltimore losing. That would elevate New York to a No. 5 seed.

Worst-case scenario: A loss to Buffalo would further accelerate New York's late-season slide entering the playoffs. This could very well happen with the Jets not planning to play quarterback Mark Sanchez (shoulder) for the entire game if at all.

Indianapolis (9-6)
Best-case scenario: A No. 3 playoff seed. That will happen if the Colts defeat Tennessee and Kansas City loses at home to Oakland. The Chiefs and Colts would both finish 10-6 but Indianapolis would hold the tiebreaker edge for the No. 3 seed because of its prior victory over Kansas City.
Worst-case scenario: The Colts get eliminated with a loss to the Titans and a Jacksonville win at Houston. That's because the Jaguars would have a better division record (4-2) than Indianapolis (3-3).

Jacksonville (8-7)
Best-case scenario: Indianapolis gets upset at home by Tennessee and the visiting Jaguars best Houston to win the AFC South.
Worst-case scenario: The Jaguars can't overcome the absence of quarterback David Garrard (thumb) and running back Maurice Jones-Drew (knee) and eliminate themselves by losing to the slumping Texans.
