As expected, the Pittsburgh Steelers lost defensive backs coach Ray Horton to the Arizona Cardinals. Arizona has pursued Horton following Super Bowl XLV and announced Wednesday that he will become the team's new defensive coordinator.

There was speculation the Cardinals and head coach Ken Whisenhunt, a former Pittsburgh assistant, would go after defensive coordinator Dick LeBeau or linebackers coach Keith Bulter, but neither were leaving the Steelers. Butler is considered the top in-house candidate to replace LeBeau if he retires.

Horton will look to bring Pittsburgh's aggressive style to Arizona and did a solid job coaching players such as safety Troy Polamalu and Ike Taylor. The Steelers were No. 2 in total defense last season.
