The Dallas Cowboys hired Rob Ryan as their new defensive coordinator, a league source confirmed Sunday.
Ryan has one year remaining on his contract with the Cleveland Browns, but he wasn't expected to return after the team fired coach Eric Mangini and replaced him with St. Louis Rams offensive coordinator Pat Shurmur. Dick Jauron is the front-runner to take over the Browns' defense, La Canfora reported, although he's also in the running for the Philadelphia Eagles' coordinator job.
The Cowboys had been seeking a full-time defensive coordinator since firing head coach Wade Phillips, who also ran the unit. Paul Pasqualoni served as the interim defensive coordinator under Jason Garrett for the last part of the 2010 season, but he accepted the University of Connecticut's head-coaching job last week.
Under Ryan, the Browns' defense finished 20th in points allowed per game (20.8) and 22nd in yards allowed (350.1). Cleveland went 5-11 for the second consecutive season, leading to Mangini's dismissal.
Ryan played college football at Southwestern Oklahoma State and landed his first pro job when he joined his father's Arizona Cardinals staff as defensive backs coach.
