The Cowboys have finalized their staff with the addition of Adam Kleffner as assistant offensive line coach. Kleffner joins the Cowboys from Missouri where he was a quality control coach focusing on the line and earned positive marks from offensive coordinator Derek Dooley, the former Cowboys' receivers coach, and offensive line coach Brad Davis. Marc Colombo was named the offensive line coach midway through last season and Hudson Houck ended the year as a consultant. Colombo signed a new deal after the season. Steve Brown, who helps with running backs and is an offensive assistant, will return as will Andre Gurode and Phillip Tanner as defensive end special teams assistants respectively.
