After acing a two-year trial as graduate assistant, James Barrett steps into a full-time role in 2023-24 as assistant coach.
Head coach Mike Boynton announced the promotion in early August of 2023:
"Coach Barrett has been an integral part of our staff for the last two seasons. He has worn many hats behind the scenes, and I am thankful that we are able to reward his hard work with a promotion to assistant coach. He will continue to help with on-campus recruiting and – with the new staff opportunities available – will also continue to help us with our on-court development program."
Barrett, a Brooklyn native who finished his playing career at Sam Houston State, climbed the coaching ladder as an assistant at the high school and junior college levels and became a key figure in the summer hoops scene through his involvement with EYBL's New York Rens and as founder of the Unsigned Hype Unlimited showcase.
Along the way, Barrett has had a hand in the development of 10 future NBA players, including Isaiah Whitehead, Jose Alvarado, Hamidou Diallo and Jordan Nwora.
In 2020 Barrett was recognized on Silver Wave Media's list of the 50 most-influential coaches in JUCO basketball after helping Seward County (Kan.) and Monroe College to consecutive NJCAA national tournament appearances.
Seward finished 28-6 and won the 2019 Jayhawk West and Region VI titles. Texas State signee Isaiah Small was a first team all-region pick and the conference defensive player of the year.
Monroe was unable to compete for the 2020 national title due to COVID-19 but ended with a 24-9 record and the Region 15 title. Stony Brook signee Juan Felix earned second team All-American status.
Barrett’s relationship with Boynton traces back more than two decades to Bishop Loughlin High School in Brooklyn, N.Y. Boynton was a senior captain during Barrett’s freshman year, and the two stayed in touch.
Barrett eventually transferred to Abraham Lincoln High where he won a state title in 2003 while playing alongside future lottery pick Sebastian Telfair. After two years at the junior college level, he finished his career at Sam Houston State, where he completed his bachelor’s degree in Kinesiology.
