Jon Diebler recently completed his fourth season on Thad Matta’s Butler staff. Originally hired as the program's director of recruiting in April of 2022, Diebler moved into an assistant coaching role when the NCAA expanded the number of staff members who could serve as on-court instructors.
Diebler is involved in all aspects of the program with an emphasis on player development, recruiting and scouting. Diebler has helped Butler to a pair of postseason berths as the team made the 2024 NIT and the field for the inaugural College Basketball Crown in 2025. The Bulldogs have won two in-season tournaments -- the 2024 Arizona Tip-Off and the 2025 Greenbrier Tip-Off -- during his time on staff as well.
Michael Ajayi earned both AP All-America honorable mention and All-BIG EAST first team recognition during the 2025-26 season, setting a new Butler single-season rebounding record.
After retiring as a player, Diebler started his coaching career with the Charlotte Hornets, serving in a video/basketball operations position during the 2021-22 season.
Diebler played for Matta from 2007-11 before being drafted by the Portland Trailblazers in the second round of the 2011 NBA Draft. He then embarked on a professional playing career over the next decade with stops in Greece, Turkey, and Israel.
Diebler is one of the most prolific scorers and shooters in Ohio State history. His 374 career three-pointers are the most in program history (only Jordan Bohannon of Iowa has made more in Big Ten history), while his 1,536 points are No. 15 in the Buckeyes’ record book. Diebler shot 41.6 percent from three-point range for his career, including a 50.2-percent mark as a senior, the best in Ohio State history.
Selected as Ohio's Mr. Basketball in 2007, Diebler once scored 77 points in a game, averaged 41.2 as a senior and ended his high school career with 3,208 points, still the state record.
Diebler and his wife, Caitlin, have a daughter, Ava, and a son, Jayce (who are twins).
