There are 8 games left in the season. Right now they are 3-5, but 3 of the remaining games are against Division rivals. The Nov. 20 game against the Giants is one that is a must win, as is the December 24 game against the Cowboys, even though by the Cowboys game we'll probably already have a good idea of how they have to do or if it's a moot point.
In a better position are the Cowboys, who play 4 of their last 8 games against Division rivals, including 2 against the Giants. At 4-4, beating the Giants twice would even the Division for them. In addition, the Cowboys last games are against decidedly poor opponents (going by records only, of course).
In the last 8 games, the Cowboys only play 3 games against teams with a winning record - and two of those are the Giants. The other is Buffalo and it's in Dallas.
Home games:
Buffalo - 5-3
Miami - 1-7
Giants - 6-2
Philly - 3-5
Away Games
Washington - 3-5
Arizona - 2-6
Tampa Bay - 4-4
Giants - 6-2
So I see the next 8 games going about 6-2, which would put them at 10-6 for a good shot at at least a wild card.
