The San Francisco 49ers moved swiftly to address their defensive coordinator position, as head coach Kyle Shanahan relieved Steve Wilks of his duties, he announced on Wednesday.
It had been an up-and-down year with Wilks at the helm, as the 49ers defense had struggled at times, especially late in the season before performing well in the Super Bowl.
In justifying his decision, Shanahan pointed out the struggles with how Wilks utilized the front seven, which led to an inconsistent run defense and an apparent disconnect between the head coach and the coordinator.
