Week 4 of the 2010 NFL season is in the books and it is that time of the week to update the NFL power rankings.
Another week, another set of surprises.
The Kansas City Chiefs are the final undefeated team in the NFL after both the Bears and Steelers lost their first game of the season.
Week 5 will be tough for the Chiefs since they get to face the Indianapolis Colts, who just lost their second game of the season and Peyton Manning will be playing as hard as ever.
Without delay, I am Daniel Wolf and I am the AFC Featured Content Coordinator and Assignment Desk Editor for Bleacher Report and here are your NFL power rankings.
