Sensational KC D not sustainable
Defense has ignited a huge turnaround for Chiefs, but it could soon falter
While the offensive improvement with new coach Andy Reid and quarterback Alex Smith is getting a healthy share of the accolades for the Chiefs' surprising 2013 turnaround, the real headline lies on the other side of the ball. The 2013 Chiefs defense is off to a blistering start. So good, in fact, that warning sirens should be blaring in every corner of Arrowhead Stadium.
Defenses that have dominated in similar ways to the Chiefs have a bad history of fading late in the season and in the playoffs -- with one notable exception.
To see why Kansas City's defensive luck may soon run out, you must be an ESPN Insider.
