Eberflus served as a Cowboys assistant coach under Jason Garrett for seven seasons. He joined the team as a linebackers coach with Rob Ryan as defensive coordinator, running a 3-4 scheme and remained when the Cowboys switched to a 4-3 under Monte Kiffin and Rod Marinelli.

The Chicago Bears have already made a major splash in their offseason when they hired Ben Johnson as their new head coach. The former Lions offensive coordinator was rated as the lead head coaching candidate for teams that needed new sideline bosses and the Bears were able to secure his services shortly after Detroit's season came to an end.
