The Cardinals will attempt to sign Steelers linebackers coach Keith Butler as their new defensive coordinator, according to Jason La Canfora of the NFL Network.
Butler and Arizona head coach Ken Whisenhunt worked together in Pittsburgh from 2003-06 when Whisenhunt served as Pittsburgh's tight ends coach and offensive coordinator.
Butler would likely accept the position if it were offered to him, according to La Canfora.
The way we see it
The Cardinals finished with the league's 29th-ranked defense last season. Butler would bring a rich tradition of successful Steelers defenses with him as the Cardinals' organization attempts to turn things around.
