Koy Detmer, Jr., Wolverine
Koy Detmer, Jr. has been hired as Michigan’s quarterbacks coach under Kyle Whittingham.
Detmer is the son of former Colorado and NFL quarterback Koy Detmer and the nephew of former BYU Heisman-winning quarterback Ty Detmer. Koy, Jr. played at BYU and Texas A&M-Kingsville, where he was a record-setting quarterback (records set: 37 completions and 65 attempts in one game) and once threw for 450 yards in a game. Koy, Sr. is now a high school head coach at Somerset (TX) Somerset.
Detmer the Younger became a running backs coach at Texas A&M-Kingsville in 2020-2021 and then moved on to Syracuse as a graduate assistant in 2022-2023. He followed offensive coordinator Jason Beck from Syracuse to New Mexico in 2024 and then to Utah in 2025.
I know some people have wanted a big name as a QB coach for Michigan, but if we’re being honest, most “big names” who work with quarterbacks are going to be offensive coordinators or passing game coordinator and not just QB coaches. Detmer is an up-and-comer who has worked with high-powered offenses and who has a couple former NFL quarterbacks in the family, so just on its surface, this seems to be a pretty solid hire. And as far as names go, there really aren’t many bigger family names than “Detmer” in the quarterback world.
