The Dallas Cowboys have rebuilt their defense around new coordinator Christian Parker, but can a new system, new starters and completely different responsibilities come together before Week 1?

On this episode of The Dallas Cowboys Daily Blitz on FanStreamSports.com, Timm “IndyCarTim” Hamm breaks down Parker’s massive challenge—and why the Cowboys’ season may depend more on their defense than on Dak Prescott.

Dallas has serious defensive talent, including Quinnen Williams, Kenny Clark, Rashan Gary, Caleb Downs, DeMarvion Overshown, Donovan Ezeiruaku and Jaishawn Barham. But talent won’t matter if the linebackers hesitate, the secondary can’t communicate or the new scheme becomes too complicated to execute.

Can Christian Parker build a fast, aggressive Cowboys defense? Or will another system change create more confusion than pressure?
