The Dallas Cowboys remain behind head coach Jason Garrett despite another 8-8 season where they missed the NFL playoffs. They plan, however, to move on from his defensive coordinator, Monte Kiffin.

Fox Sports' Jay Glazer reports while Garrett is "safe", Kiffin "will be gone" after just one season on Garrett's staff. According to multiple reports, the 73-year-old is expected to be either fired or pushed into retirement.

Kiffin replaced Rob Ryan and installed a 4-3 defense, but despite an increase in takeaways, the Cowboys got gashed by air and ground in terms of yardage. Although injuries played a big part, they were undisciplined, giving up big plays and struggling on third down. Dallas finished last in total defense, 30th in pass defense and 27th in run defense.

The Cowboys should keep their 4-3 base, and candidates to take over their Tampa-2 scheme include current defensive line coach Rod Marinelli and just-fired Minnesota Vikings head coach Leslie Frazier.
