Indianapolis Colts coach Chuck Pagano had hoped to tap into the Pittsburgh Steelers' coaching tree to fill his coordinator spots. He was successful in luring Bruce Arians to run his offense but Keith Butler, his choice to run the defense, reportedly won't be coming. The Pittsburgh Post-Gazette reported that Butler, Pittsburgh's linebackers coach, decided to cancel his scheduled Tuesday interview with the Colts after meeting with Steelers president Art Rooney II and coach Mike Tomlin on Monday.
