The Cowboys finalized the hiring of Rod Marinelli as defensive line coach Friday, beginning a trickle-down effect for the rest of the defensive coaching staff.

PODCAST
Cowboys defensive end Jason Hatcher joins Ben and Skin in studio to talk about his famous response to the leadership question the last time he was on the show, his development as a player, the transition to Monte Kiffin's Tampa 2 defense and much more. Listen

With Marinelli on board to coach the defensive line, Brian Baker's time with the Cowboys appears to be over.

The defensive coaching staff will have some familiar faces in 2013, with Jerome Henderson (secondary) and Matt Eberflus (linebackers) returning to the coaching staff. If Rob Ryan becomes the defensive coordinator in St. Louis, it will be interesting to see if he tries to hire Eberflus. But the Cowboys might block any potential move by Eberflus.

The offensive coaching staff still needs some work. Skip Peete, the Cowboys' former running backs coach, has been hired in Chicago, and the Cowboys have yet to hire a replacement.

Former Arkansas and Ole Miss coach Houston Nutt interviewed with the Cowboys this week for an offensive position, maybe the running backs job or possibly the tight ends gig. Tim Spencer, who was released of his duties in Chicago this week, is a possibility. Anthony Lynn, a former Cowboys coach now with the New York Jets, has one year remaining on his contract. The Cowboys have tried to hire Lynn in the past, but the Jets have not allowed them to interview him.

John Garrett is still employed at Valley Ranch as the tight ends coach, but he applied for a head coaching job at Delaware and didn't get an interview. Dave Brock, an assistant coach at Rutgers, took the job Friday.

There are rumors Garrett might not return in 2013. If Garrett leaves, there's a chance Mike Tice, the former offensive coordinator in Chicago, could take the position.

The Cowboys also need to hire a special teams coach to replace Joe DeCamillis, who took that position in Chicago and was also named assistant head coach.

Steve Hoffman, a former Cowboys kicking coach, is free after his time in Kansas City ended in 2012. Rich Bisaccia, the San Diego Chargers' special teams coach the last two seasons, who also worked in Tampa Bay when Monte Kiffin was there, could be considered.
