The Dallas Cowboys made a major change with the defensive staff entering Week 16, announcing that defensive coordinator Matt Eberflus will not be on the sideline for the final three weeks of the sideline as speculation about the hot seat heating up.

Eberflus will be in the coaching booth for the remainder of the season, while defensive line coach Aaron Whitecotton will be given increased duties moving forward.

According to Eberflus, Whitecotton will be the man “spearheading” adjustments on defense.

It’s an interesting move with three weeks remaining, and following comments from owner and general manager Jerry Jones that the final games will be used for evaluation of the players and coaching staff, including Eberflus.
