While KC has a lot of problems as an NFL defense, they tend to be a pretty good fantasy defense. If you league favors defense action over offensive inaction (i.e. Two sacks are worth enough to overcome a game where they give up 36+ pts), KC can be a good option. If your league gives pts to def for return yards and/or Return TDs, KC becomes even more valuable because of Hall. Plus they get to play the Chargers twice and the Raiders twice.
