The first key is; "Charles can't be in charge,." That is Chiefs running back Jamaal Charles, who's been known to take over a game running the football during his career. If you let him get started early, he can be a load.
The second key is to limit the big plays. Nearly half of the Giants 450 yards passing last week came on just six of Eli Manning's 21 throws. The Cowboys must do a better job of squeezing the Kansas City Chiefs wide receivers inside, and making sure their safeties attack underneath.
The third key is to watch for the blitz. With the Kansas City Chiefs new 3-4 alignment, they like to do a lot of blitzing. As a matter of fact, in the season opener against the Jaguars they blitzed a lot and ended up with six sacks. The Cowboys can't have that and especially with quarterback Tony Romo playing with those bruised ribs.
Those are your Silver Star Nation keys to a Cowboys victory against the Kansas City Chiefs.
