The easiest route into playoffs (and it isn't easy) with the best odds of happening is for the Bills to win Texans, Jets (those are must wins) and 2 of the 3 NFC games. They don't need to win out. The Steelers, facing all AFC teams from here on, can't lose more than one of their remaining games and they face Colts in Indy this weekend, Bengals in Cinci, Broncos at home and then Baltimore and Cleveland both away. That is not easy for Pitt either. I believe big Ben may be out this weekend which could be a big break.
I know there is a lot of doom and gloom here and I'm not saying it will happen, I'm just presenting the facts.
