In most cases, it would be premature to call for a head coach's or coordinator's job less than a month into the season. However, it is absolutely warranted in Matt Eberflus' case after the Dallas Cowboys' defense offered zero resistance against a Bears offense that couldn't get out of its own way before Sunday.
It is beyond clear that Week 1 was a product of the Eagles refusing to throw the ball downfield. The Cowboys don't just have the worst defense in football, but they are on pace to be one of the worst defenses in the history of the franchise.
