Detroit is 6-5, but they have a real tough schedule coming up, so I don't see them making the playoffs.
It will come down to one of these 5-6 Teams against the Giants:
Philly
Washington
Chicago
Minn
Saints
Arizona
Panthers 4-7
It's nearly impossible to predict because all of these teams have been inconsistent as fuck all year.
As much as I hate to say it I don't think da bears will go because they have a tough schedule, with three away games:
NYG (in Chi)
in WAS
in Min
GB (in Chi)
in NO
Philly also has a pretty tough schedule (NYG, DAL, NO, BUF) so they may not make it unless they go 3 out of 4.
Redskins have Chi, NYG, MIN, and Dal. They are out, they will lose 2 of those games.
The Saints and Arizona have the easiest schedule.
I'm going to go out on a limb and say AZ against Giants. Logic says Philly though.
