Four non-division leaders in the NFC have better records than Seattle and Arizona at present. But ESPN's NFL Playoff Machine does show scenarios whereby Seattle or Arizona could qualify for postseason.
The scenarios I put together show Dallas winning the NFC East at 8-8. The New York Giants, Chicago Bears and Atlanta Falcons would miss the playoffs at 8-8. Arizona or Seattle would emerge as the fifth seed, with 9-7 Detroit as the sixth seed.
There are other ways to make these playoff dreams come true.
The Cardinals have three of their final four games at home, with a road game against Cincinnati. Arizona and Seattle play in Week 17.
The chart shows remaining schedules for Arizona, Seattle and five other NFC teams in the hunt.
