Their next 2 games are for Jax and at TN. If they win those and get to 5-5, they'll still think they're in it. Hopefully the stretch of Bills-Colts-Chiefs will put that to rest between 11/20-12/7.
But even if they come out of that 6-7 (the kids will love it!) then they have very winnable games vs. the Cards and the Raiders that could get them to 8-7. Then @ Chargers and home for the Colts. 
Unless there's a total collapse, I have a bad feeling they tread water the rest of the year and don't try to have some tactical losses.
