The strength of the team is their D. Turnovers or not they don't allow teams to score much against them. Their ppg is one of the best in the AFC and not too far off from Seattle or Minny.
With Denver's problems on offense I don't see the Chiefs getting swept by them but I could see them stumbling at Denver, and the offenses of Oak, Tenn and Atlanta could definitely give them trouble. Not too many teams can pile up wins vs. quality opponents, it wouldn't' surprise me for the Chiefs to finish 3-3 with their remaining schedule.
