The Cowboys have serious problems. That was evident watching them this past Monday night. But don't overreact to that game. Washington is worse than Dallas. 
Washington has trailed by double-digits with the ball in every one of its games. Only one team can match that embarrassing mark - and it's not the Cowboys but the Jets. 
Andy Dalton will have had two weeks of working with the Cowboys' first-string offense. He's a decent QB when he's surrounded with skill position weapons, which he has with the Cowboys. Washington can't come close to matching the Cowboys' offensive talent. 
So the Cowboys defense doesn't face a stiff challenge here like they did in five of their previous six games. 
The Cowboys have covered 79 percent of their last 19 division games.
