The Cowboys defense will be going through some changes in 2020. Obviously there will be personnel changes as players move on in free agency and the team adds players through that same process and in the draft. More than just personnel changes will occur this year, though, as the team has a new head coach and a new defensive coordinator.
Mike Nolan is the man to lead the defense in this new era of Cowboys football, and considering the inconsistent play of the defense recently, he has challenges to overcome. Nolan has a long history in the NFL as a coach and his father was also a coach, so experience and knowledge are in abundance.
