AJ Johnson

Johnson is a young NBA guard who arrived in the league via a professional stint in Australia's National Basketball League. He played for the Illawarra Hawks before signing with the Dallas Mavericks, joining an organization with playoff ambitions. His path to the NBA included a notable physical transformation and a brief but eventful high school journey across multiple programs.

Born on December 1, 2004, in Fresno, California, Johnson spent his early years in the same basketball circles as Phoenix Suns guard Jalen Green, whom he described as a big-brother figure. Around 2020, during the COVID-19 pandemic, Johnson experienced a growth spurt that took him from 5 ft 10 to 6 ft 5. That shift dramatically altered his basketball trajectory and recruiting standing.

Johnson began his high school career in Fresno before transferring to Taft High School for two years. He emerged as one of the most significant risers in the 2023 class, parlaying his newfound size into combo-guard status. For his senior year, he enrolled at Donda Academy in Simi Valley, California, but after the school closed, he completed his final season at Southern California Academy. He signed with agent Bill Duffy and WME Basketball representation ahead of his professional move.

Rather than pursuing the traditional collegiate route, Johnson signed with the Illawarra Hawks of the Australian NBL. He spent the season developing against adult professionals in a league known for producing NBA-ready prospects. His Australian tenure provided experience in physical, pace-driven basketball before he transitioned to the Dallas Mavericks roster.

On the court, Johnson operates as a combo guard with the size to play off the ball and the handle to initiate offense. His late growth spurt gave him wing measurements while retaining guard skills, allowing him to defend multiple perimeter positions and attack closeouts. His development focus centers on consistency as a shooter and decision-maker against NBA-length defenders.

Johnson begins the 2025–26 season as a developmental guard on the Dallas Mavericks. His résumé includes professional experience in Australia, a rapid physical ascent during his mid-teens, and a high school career that spanned Taft High School, a brief stay at Donda Academy, and Southern California Academy.
