Bills aren't done yet.
JA17 is back has shown he can compete with the best teams in the NFL so winning out doesn't seem as improbable anymore but they would have to do so despite McD and the NFL officiating. If they win their last 5 and the Dolphins drop their week 16 and 17 games against Dallas and Baltimore, the Bills take the Division and 4th seed.
If the Bills drop one more game, they certainly need more help now but it's still possible. All eyes have to be on Pittsburgh and Cleveland. They do have softer schedules but they are not great teams right now so anything can happen.
Cleveland's last 6 games are against the Rams, Jacksonville, Chicago, Houston, Jets and Bengals. Their backup QB Dorian Thompson-Robinson went out of the game with a concussion yesterday so who knows what kind of answer they have at QB going forward. It's quite possible they lose 4 of their last 6 games in which case the Bills get in.
Pittsburgh played slightly better this week but they're still one of the worst offenses in the league this year. They do have a softer schedule to close things out as well but anything can happen when your O can't put up points. Next 6 games for them are Cardinals, Patriots, Colts, Bengals, Seahawks, Ravens. They would also need to lose 4 of those games for the Bills to get in.
