Former Duke men's basketball captain Amile Jefferson joined the staff at his alma mater in July 2021. He spent his first season as the team's director of player development before being promoted to assistant coach by head coach Jon Scheyer in April 2022. It was announced in July 2023 that Jefferson had accepted an assistant coaching role on the staff of the NBA's Boston Celtics.
In his first season on staff, Jefferson helped the Blue Devils claim the ACC regular season title outright and advance to the Final Four for the 17th time in program history. Promoted to assistant coach prior to his second year at Duke, Jefferson was part of the the team's ACC Tournament title during Scheyer's first year as head coach.
Jefferson was anchor on the defensive end for Duke during his playing career and carried that mentorship to the coaching ranks with the development of Mark Williams in 2022 and Dereck Lively II in 2023. Williams was the ACC Defensive Player of the Year as a sophomore after leading the conference and ranking 12th nationally with 110 blocked shots. Lively earned spots on the ACC All-Defensive Team, the ACC All-Freshman Team and the ACC All-Tournament Team after his 82 blocks ranked second in the ACC, eighth nationally and led all Division freshmen.
The Philadelphia native rejoined the Blue Devils in 2021 after a professional playing career that included time with the NBA G-League's Iowa Wolves (2017-18), Orlando Magic (2018-20), Boston Celtics (2020) and the Turkish Basketball Super League's Galatasaray (2020-21).
As a five-year letter winner, a national champion and three-time team captain at Duke from 2012-17, Jefferson played in a program-record 150 games with 103 starts, averaging 7.2 points and 6.3 rebounds per contest. He played in 67 home victories (most in program history) and 124 total victories (third most in program history), while his .971 home winning percentage (67-2) ranks as the second best among any Duke player.
Off the court, Jefferson remains the only player in Duke history to be named to the All-ACC Academic Team four times. He served as a team captain for three seasons – becoming the only Blue Devil in the Coach K era to do so – and was a finalist for the Senior CLASS Award in 2016-17. He earned his undergraduate degree in history from Duke in 2016 and received a master's degree from Duke's Divinity School in 2017.
