Amid a season full of offensive struggles, Oklahoma has a new offensive coordinator.

Per ESPN's Pete Thamel, Washington State offensive coordinator Ben Arbuckle has agreed to a three-year deal with the Sooners. He replaces Seth Littrell, who Oklahoma fired in October.

Arbuckle took over as Washington State's offensive coordinator in 2023 and found immediate success, coaching Cam Ward, now a Heisman Trophy candidate at Miami, as he threw for 3,735 yards and 29 touchdowns a season ago. The Cougars' current John Mateer, threw for 3,139 yards and 29 touchdowns this year.

Before he arrived at Washington State, Arbuckle was the offensive coordinator at Western Kentucky in 2022, when quarterback Austin Reed led the national in passing yards with 4,746.

Under Arbuckle, the Cougars finished No. 12 in scoring offense, No. 9 in pass efficiency and No. 22 in total offense on their way to an 8-4 record.

In its first season in the SEC, Oklahoma finished 121st nationally in total offense and went 2-6 in conference play and 6-6 overall. It fired Littrell on Oct. 20 following a 35-9 loss to South Carolina.

Arbuckle will have plenty of pieces to work with in Norman assuming the Sooners retain most of their key players this offseason. The group is highlighted by sophomore Jackson Arnold, who was the No. 4 quarterback in the Class of 2023 according to 247Sports Composite.

Arnold had a forgetful first season as the Sooners' starter, throwing for just 1,421 yards and 12 touchdowns, but could be due for a big leap in Arbuckle's offense.

While Oklahoma's offense struggled in 2024, its defense performed well, coming in at No. 22 nationally in total defense. If the Sooners can continue their defensive approach while getting an offensive boost from Arbuckle, they could be on their way to a turnaround season.
