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.

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.

Dallas' new defensive coordinator carries a well-earned reputation for safe playcalling. Whether or not that's a winning formula depends on more than just him.
