On the first weekend of December, four teams made the NFL playoffs.
With four weeks to go in the regular-season, New England owns the AFC East title, Denver has the AFC West and Atlanta won the NFC South.
Houston has not clinched the AFC South, although it has a three-game lead over Indianapolis, but it secured at least a wild-card spot on Sunday.
The Patriots beat Miami 23-16. Denver defeated Tampa Bay 31-23, and with that loss by the Bucs, the Falcons were guaranteed their division title.
The Texans beat Tennessee 24-10.
