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.

In his new introduction and re-introduction to Dallas on Tuesday, Eberflus said his goal for Dallas’ defense is ‘pretty simple.’

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.
