Rob Ryan's defense is under siege

The Dallas Cowboys' defense is under siege.

In the last 22 drives it has defended the unit has allowed 11 scores, including eight touchdowns.

It doesn't matter what quarterback the Cowboys face; defensive coordinator Rob Ryan is not going after him. He's not sending five or six defenders at rookies or veterans. He's going to be conservative with four, maybe five pass rushers.

Whatever he's doing is not working. It doesn't look good when DeMarcus Ware knocks rookie quarterback Nick Foles down on the Philadelphia Eagles' first offensive play of the game but doesn't get to him on a consistent basis thereafter.

The Cowboys' defense is better than this, or so we think.

With four weeks remaining in a regular season that can shape the futures of many players and coaches, Ryan's defense has to perform better than it has been.
