He was also on the wrestling and track teams.
The four star tackle committed to Clemson over a number of other offers that included Ohio State.
Miller impressed early on at Clemson, becoming only the fourth true freshman on the offensive line to start since 1972 for the Tigers. He ultimately started all 14 games and was named a Freshman All-American.
He started 13 games for the Tigers in 2023 and was named third-team All-Atlantic Coast Conference.
