Not exactly. Beating the Redskins, Philly could still finish 9-6-1 with a Week 17 loss to the Cowboys, and Dallas, Chicago, and up to 2 of Minnesota, Tampa, and Atlanta can all still finish 10-6.
I'm only talking about this week. I'm not worried about next week until this week is over. Of course I understand all the possibilities, but if Philly wins today, they will be in the #6 seedd, or #5 if Atlanta loses. Then comes next week.
