If we lose, it is over. 8-8 will not win the division considering tie-breakers, especially if 3 teams are involved.
The playoffs started for Dallas with the Miami game. I think we need to get to 9-7 and win out, to hold any tie breakers.
I don't follow this about the tiebreakers.
If we sweep the Commanders, we finish 4-2 in division and hold the tiebreaker against them.
The Giants and Eagles still have a game against each other. The loser will have a division record no better then 3-3.
If the Commanders manage to beat the winner of the Giants-Eagles game, then we hold all tiebreakers in the division.
That's four games, and nothing unreasonable or unlikely about any of them. Let's look at only those games. If the Giants beat the Eagles and lose to the Commanders, the records are:
Giants: 6-6
Cowboys: 5-7
Eagles: 4-7
Commanders: 5-8
If the Eagles beat the Giants and lose to the Commanders:
Giants: 5-6
Eagles: 5-7
Cowboys: 5-7
Commanders: 5-8
In either case, it's very easy to envision the 8-8 Cowboys winning the division.
