"We are excited to announce Keith Butler as our defensive coordinator," Steelers coach Mike Tomlin said in a statement released by the team. "Keith has been an integral part of our defensive game planning and schemes for several years and we look forward to him moving into the role of calling the defense. His passion and energy will be important to us taking the next steps to being one of the top defenses in the NFL."
