8. Kansas City Chiefs (9-3, Previous: 6)
After jumping out to a 21-7 lead over the Broncos on their home turf, the Chiefs succumbed to the majesty of Peyton Manning’s arm and suffered their third-straight loss after a 9-0 start. Alex Smith was much more than the "game manager" he is derisively called, but his receivers and their butterfingers couldn’t make the crucial catches. On the other side of the ball, Kansas City’s suffocating defense seems to have softened over the past few weeks, giving up far more yardage than earlier in the season and collecting just two sacks in the last six weeks.
