The Mike McCarthy-era is over in Dallas, and the time has arrived for Brian Schottenheimer to lead the Cowboys. Despite hiring his new head coach from within, the lack of urgency from owner Jerry Jones allowed for the contracts of all of his assistants to expire along with that of McCarthy. 
Schottenheimer has already made the two most important hires in his first career head coaching gig, bringing on Klayton Adams as offensive coordinator and Matt Eberflus as defensive coordinator. Now, both coordinators have begun building their new staffs.
On offense, the team has hired Derrick Foster as their new running backs coach, per Nick Harris of the Star Telegram. Foster first came to the NFL after three years as a running backs coach at Iowa. He began in Los Angeles, where he coached Austin Ekeler through his two best seasons as a Charger, before spending last year in New Orleans coaching Alvin Kamara. He’ll inherit a running backs group that returns Rico Dowdle, Deuce Vaughn, and Malik Davis, though his position has certainly been bookmarked as one needing improvements in the offseason, potentially through the draft.
We saw the Cowboys interview one of its former running backs, Tashard Choice, for the position, as well. According to Clarence Hill Jr. of All City DLLS, Choice will be staying in his current role with the Longhorns. Though he was also in consideration for roles with the Raiders and Saints, a raise in excess of $800K will keep Choice in Austin.
While Adams brings plenty of offensive line experience to the offense, the Cowboys have brought in Kansas State co-offensive coordinator and offensive line coach Conor Riley as their new offensive line coach, per Hill. Riley has been an extremely well-respected position coach in the college coaching ranks with his other stop being at North Dakota State. He’ll make his NFL coaching debut in 2025.
Also on offense, we saw wide receivers coach Robert Prince depart for Miami. While his replacement has not yet been hired, Tiquan Underwood will be on hand after getting hired as assistant wide receivers coach, according to Albert Breer of Sports Illustrated. He takes over the position after holding the same job with the Patriots last year.
On the defensive side of the ball, ESPN’s Todd Archer reports that a slew of former Bears assistants have followed Eberflus to Dallas. We already saw reports on the arrival of defensive pass-game coordinator Andre Curtis and linebackers coach Dave Borgonzi with Eberflus, but Archer adds that David Overstreet will follow as assistant defensive backs coach and Bryan Bing will join as assistant defensive line coach. Both Overstreet and Bing held those same positions on Eberflus’ defense in Chicago.
There are still some vacant positions on the Cowboys staff to fill out, but Dallas is working quickly to make some big hires after getting a late start to the market. With Schottenheimer’s inexperience as an NFL head coach, the supplemental ability of his coaching staff will be crucial.
