Former defensive coordinator Rob Ryan was shown the door after the Cowboys missed the playoffs this season. Everyone knows that Jones isn't going anywhere and for some strange reason head coach Jason Garrett remains safe in his job. So someone had to go.
The Cowboys are looking to fill their defensive coordinator void and have former Tampa Bay Buccaneers defensive coordinator Monte Kiffin topping their list. Kiffin,72, won a Super Bowl in Tampa Bay, recently resigned from the same job at USC, where his son Lane was the head coach. If Kiffin is named defensive coordinator look for the Cowboys to move from a 3-4 alignment to a 4-3, which would be a key to the Cowboys changing to a Tampa 2 defense.
There was talk of Kiffin possibly joining Andy Reid on the Kansas City Chiefs staff, but the story is that Kiffin wasn't interested in the job.
Jones, Kiffin, or Garrett couldn't be reached for comment, so as of now this is more rumor than fact.
