There are two things we can be assured of: it’s the beginning of a new decade and the final week of the NFL regular season.

What we can’ be assured of is what teams will make the AFC playoffs; and the AFC playoff scenarios have seemingly endless possibilities.

What we do know is that four teams have clinched an AFC playoff spot: the Colts, Patriots, Bengals and Chargers. Six other teams are vying for the final two AFC playoff spots: the Jets, Ravens, Steelers, Texans, Jaguars and Dolphins.
