In a matter of hours, Dallas Cowboys head coach Jason Garrett appeared to reverse course on whether his coaching staff will remain intact over the offseason.

During an interview Monday on 105.3 The Fan in Dallas, Garrett said offensive coordinator Scott Linehan would be back for the 2019 season and that he didn't plan on reshuffling his staff (h/t the Dallas Morning News' Jon Machota).

Later in the day, Garrett appeared less certain:

According to the Star-Telegram's Clarence Hill Jr., Garrett added that team owner Jerry Jones will have the final word on the team's assistants.

Stephen Jones, the team's executive vice president, also said on 105.3 The Fan the Cowboys aren't prepared to make any guesses about the structure of the coaching staff, per Machota:

"At the end of the day, we had a good year, but at the same time we have to really analyze this. I know certainly overall it was a good season, but we also know that we've had some good teams around here that haven't taken the next step. We've got to figure out what that is, and obviously we're going to be doing a lot of work in trying to uncover every stone to see how we can take that next step."

Linehan would be the most obvious assistant whose job could be in serious jeopardy.

The Cowboys gained just 308 total yards in their 30-22 NFC Divisional Round defeat to the Los Angeles Rams. Their general offensive futility was a theme throughout the year.

Dallas averaged 343.8 yards per game (22nd) and ranked 24th in offensive efficiency, per Football Outsiders. The arrival of Amari Cooper provided a momentary boost, but the effect faded toward the end of the regular season and into the playoffs.

Nobody would be surprised if Garrett and Jones decide to let Linehan go in the hope of turning the unit around in 2019.
