Who Is the Biggest X-Factor on the Cowboys Defense?

NFL Draft 365Official AccountJune 3, 2012

The Dallas Cowboys and the good people of the Metroplex are beginning to lose the taste of the playoffs, and more specifically, winning playoff games.

The last time they won a playoff game was in the 2009 Wild Card round, but they went no further. Dallas' glory days seem to be a thing of the past, as the Cowboys lack consistency on both sides of the ball year-in and year-out.
Tony Romo can post major numbers, but it's the defense that lets the team down, and the next year, vice versa.
Entering 2012, Dallas should have a solid offense, led by the aforementioned Romo, who has some serious weapons in Dez Bryant and DeMarco Murray. So it's the defense we turn our focus to as training
camp approaches.
It's a defense led by DeMarcus Ware, who ranked second in the league last year with 19.5 sacks. But, beyond Ware, who is going to step up and give Dallas a deep, strong overall defense.
Bleacher Report NFL experts Eric Frenz and Aaron Nagler are keyed into linebacker Sean Lee and defensive end Anthony Spencer to elevate their game next season.
