If you have plans on Sunday afternoon, you might want to cancel them, because the NFL will be giving us what should be one of the best regular-season games of the year when the Buffalo Bills host the undefeated Kansas City Chiefs in a game that will be kicking off at 4:25 p.

Week 11 NFL power rankings have the Chiefs climbing up the leaderboard but even at 9-0, the reigning champs still don't top every list.

The Chiefs' 15-game winning streak dating back to last season isn't an NFL record, either. The longest combined winning streak between the regular season and postseason belongs to the Patriots, who ripped off 21 straight victories from the 2003 regular season, through the 2003 playoffs and into the 2004 regular season.
