Clayton Custer was named an Oklahoma men’s basketball assistant coach on Aug. 23, 2023.
Custer returned to the Sooners after a brief stint as an assistant coach at his alma mater, Loyola Chicago. Before his time on staff at Loyola, Custer spent two seasons as the director of video operations and player development at OU from 2021-23.
During his time in Norman, Custer has worked closely with head coach Porter Moser on the Sooners’ offensive attack. He has been instrumental in the development of Oklahoma guards Xzayvier Brown, Nigel Pack, Dayton Forsythe, Javian McCollum and Milos Uzan among others.
The Sooners have won 20 or more games in each of his three seasons as an assistant coach with an NCAA Tournament appearance in 2025 and a runner-up finish at the College Basketball Crown in 2026.
In 2025-26, Oklahoma averaged 82.9 points per game as Pack (16.8 ppg., 123 3FG) and Brown (15.4 ppg., 122 assists) formed one of the top scoring backcourt tandems in the SEC. The Sooners finished the season ranked second in the conference in 3-point percentage (.365), while making the second most 3-point field goals (357) in program history.
The 2024-25 campaign saw Oklahoma return to NCAA Tournament play as Jeremiah Fears (17.1 ppg., 140 assists) emerged as one of the top lead guards in the SEC. He went on to earn All-Freshman Team honors before being selected with the No. 7 pick in the 2025 NBA Draft by the New Orleans Pelicans.
In his first season as an assistant coach, Custer helped the Sooners to a 20-win season as McCollum (13.3 ppg., 54 3FG) garnered Honorable Mention All-Big 12 honors.
Prior to his first stint on staff at OU, Custer spent one season on Moser’s staff at Loyola as director of player development in 2020-21. The Ramblers finished the year with a 25-4 record, won the MVC regular season and tournament championships and advanced to the NCAA Tournament’s Sweet 16. Loyola knocked off Georgia Tech in the NCAA first round and toppled No. 1 seed Illinois in the second round, finishing the year No. 17 in the AP poll.
Custer starred at Loyola during the 2016-17 through 2018-19 seasons, starting 99 games in his three seasons and helping the program to a 70-34 (.673) mark.
He was named Missouri Valley Conference Player of the Year as a redshirt junior in 2017-18 and started all 33 games on the Ramblers’ run to the Final Four as a No. 11 seed. Loyola finished the season 32-6 and made the Final Four for the first time since 1963. Custer earned honorable mention AP All-American accolades and averaged 13.2 points, 2.2 rebounds, 4.1 assists and 1.5 steals per outing while shooting 45.1% (60-133) from 3-point range.
He was named a third-team Academic All-American and a third-team All-MVC selection as a redshirt senior in 2018-19. Custer won the men’s 3-point title at the State Farm College Slam Dunk and 3-Point Championships at the Final Four in Minneapolis to conclude his collegiate career.
Before he joined Loyola, Custer appeared in 12 games as a freshman at Iowa State during the 2014-15 season.
He prepped at Blue Valley Northwest High School in Overland Park, Kan., earning three first-team Class 6-A All-State honors and securing a No. 92 national recruit ranking by Rivals.
Following his collegiate playing career, Custer played professionally for part of the 2019-20 season in Poland.
