Two different types of playoff races are taking place in the AFC and NFC.
The AFC only has nine teams with more than three victories and the Kansas City Chiefs have a clear lead over the rest of the field in the race for the No. 1 overall seed.
The Buffalo Bills are doing their best to put pressure on the Chiefs. They downed the Miami Dolphins with a walk-off field goal in Sunday's early afternoon window.
Over in the NFC, 13 teams have at least three wins and three of the four division races are tightly contested.
