Following his Bears ouster, Eberflus is back in the NFL, this time as defensive coordinator for the Dallas Cowboys. That means he’s effectively the lieutenant of (bizarre) first-year head coaching hire Brian Schottenheimer. And that means he’s in a position to give Schottenheimer advice about what NOT to do as a head coach.

Eberflus came to the Cowboys in 2011 working in a 3-4 defense under Rob Ryan. He left following the 2017 season after working in a 4-3 scheme under Monte Kiffin and Rod Marinelli. In his last two seasons, he served as the passing game coordinator and worked alongside Marinelli in many ways.

Matt Eberflus's run as a head coach with the Bears came to an end after he mismanaged the final seconds of a Thanksgiving loss to the Lions last November, but the ugly end didn't keep him from landing another job.
