Last week began a change in the Dallas Cowboys organization that has been a decade in the making. After nine and a half years under one head coach, the Cowboys finally having a new lead voice.
Even though there have been a few defensive coordinators during that time span, the defense has largely been the baby of Rod Marinelli. Marinelli came to Dallas in 2013 as the defensive line coach under coordinator Monte Kiffin.
Kiffin, for multiple reasons, lasted just one year. From that point forward, Marinelli has been the defensive coordinator, be it nominally or in actuality.
