He spent last season (2022) as Arizona State's offensive coordinator and quarterbacks coach, where he helped help develop a rushing attack that saw Xavier Valladay rush for 100 yards in seven games and notch the tenth-best rushing mark in school history as the transfer ran for 1,192 yards and 16 TDs, tied for fourth-most in Sun Devil history. Additionally, under Thomas's tutelage, QB Trenton Bourget broke the ASU record for all-time completion percentage in a single season (71.4%).
Prior to Arizona State, Thomas was the offensive coordinator and quarterbacks coach at UNLV (2020-21). He helped lead the Rebels to several historical accomplishments during that time, including helping running back Charles Williams break the program's career rushing record and achieve MWC First-Team All-Conference honors, becoming the first UNLV running back to earn a first-team all-league honor more than once in a career (2019). In each of Thomas's seasons at UNLV he contributed to the development of the Mountain West Freshman of the Year. In 2020, wide receiver Kyle Williams achieved the honor, while QB Cameron Friel was named to the award the following season.
