Heading into Week 17, only one AFC playoff spot was decided. The Kansas City Chiefs won the AFC West last Sunday, but the other six playoff slots were open. A loss to the Cincinnati Bengals on Sunday, though, dropped Kansas City to the No. 2 seed in the conference.
The Bengals clinched the AFC North with the win, while all but eliminating the rest of their division. The Tennessee Titans took over the top spot in the conference, while the Buffalo Bills and New England Patriots also clinched a playoff spot.
Things were a little clearer in the NFC coming into this week, as five of seven spots and three divisions were decided.
