After a single standout season at Duke University, Stanley was selected in the 2020 NBA draft and has since played for NBA franchises, NBA G League affiliates, and several teams in international leagues.
Stanley began the 2025 season in France with ESSM Le Portel before signing with BC Šiauliai of the Lithuanian Basketball League later that year. His journey from a Los Angeles prep standout to a global professional circuit reflects the modern path many young American players follow in pursuit of consistent playing time and continued development.
Early Life and Background
Cassius Jerome Stanley was born and raised in Los Angeles, California, growing up in a region of Southern California long associated with elite basketball talent. He attended Harvard-Westlake School in Studio City, California, where, as a sophomore, he averaged 17.9 points, 6.8 rebounds, and 3.5 assists per game, establishing himself as one of the more promising young players in the Los Angeles prep scene.
In 2017, Stanley transferred to Sierra Canyon School in Chatsworth, California, for his final two years of high school. The program has produced a long list of high-profile basketball prospects, and Stanley thrived in that environment. As a senior, he averaged 17.8 points, 6.2 rebounds, and 2.9 assists per game while leading Sierra Canyon to a 32–3 overall record, a season that helped cement his reputation as a top national recruit.
Path to Professional Basketball
Following his senior season at Sierra Canyon, Stanley was widely recruited by top college programs. On April 22, 2019, he committed to play at Duke University, joining a Blue Devils program with a long tradition of developing NBA talent. He enrolled at Duke for the 2019–2020 season, arriving in Durham, North Carolina, as one of the most anticipated freshmen in the Atlantic Coast Conference.
Stanley quickly translated his prep production to the college level. In his Duke debut, he scored 13 points in a 68–66 victory over Kansas, signaling his readiness for major college competition. He later produced a 22-point, six-rebound performance in a 98–96 overtime win against rival North Carolina, a performance that highlighted his scoring ability against elite competition. At the end of the regular season, he was named to the ACC All-Freshman Team. Across his lone college campaign, Stanley averaged 12.6 points and 4.9 rebounds per game while shooting 47 percent from the floor and 36 percent from three-point range before declaring for the 2020 NBA draft.
Cassius Stanley Career
Early Career (2020–2021)
On November 18, 2020, Stanley was selected in the second round, 54th overall, by the Indiana Pacers in the 2020 NBA draft. Shortly afterward, the Pacers signed him to a two-way contract that linked his NBA roster with the Fort Wayne Mad Ants, the organization’s NBA G League affiliate. The arrangement gave Stanley a chance to compete professionally in two leagues while continuing his development under the Pacers’ umbrella.
During his time in the Pacers system, Stanley also participated in the 2021 NBA Slam Dunk Contest, where he was eliminated after the opening round. Although the contest did not produce a title, his inclusion reflected the league’s recognition of his athleticism and highlight-reel ability as a young player.
Detroit Pistons and G League Stints (2021–2023)
On September 28, 2021, Stanley signed with the Detroit Pistons, only to be waived on October 16, 2021, before the regular season began. He was quickly added to the Motor City Cruise, Detroit’s G League affiliate, where he averaged 9.6 points and 4.5 rebounds per game. During that season, Stanley shuttled between the Pistons and the Cruise on a series of short-term contracts, signing 10-day deals in December 2021 and January 2022 and returning to the Cruise roster in between.
On November 3, 2022, Stanley was named to the opening night roster of the Rio Grande Valley Vipers, continuing his work in the NBA G League. The stint with the Vipers allowed him to log consistent minutes as a featured perimeter scorer and helped him refine his game away from the bright lights of the NBA parent organizations.
International Move (2023–2025)
On September 21, 2023, Stanley signed with Hapoel Afula of the Israeli Basketball Premier League, marking his first sustained professional engagement outside the United States. The Israeli league provided Stanley with a heavier on-court workload and a chance to play a featured role on a senior professional roster.
Stanley returned to the United States on October 27, 2024, when he joined the Valley Suns for the 2024–2025 NBA G League campaign. On April 9, 2025, he moved to Europe again, signing with ESSM Le Portel of France’s LNB Pro A, a top-tier French professional league. The French stint gave him exposure to a different style of European basketball before his next career step.
BC Šiauliai Era (2025–Present)
On July 23, 2025, Stanley signed with BC Šiauliai of the Lithuanian Basketball League (LKL), returning to elite-level European competition. The club later released a statement on August 21 indicating that Stanley had not passed his required medical examination, temporarily complicating his availability. He recovered from the injury in the months that followed, and on December 18, 2025, Stanley returned to the Šiauliai lineup, resuming his role as a versatile perimeter contributor in the Lithuanian top flight.
Playing Style and Strengths
Stanley has built his career on a combination of size, length, and above-the-rim athleticism. Listed at 6 feet 5 inches, he is comfortable operating as either a small forward or a shooting guard, and he has shown the ability to score inside the arc, knock down spot-up threes, and finish in transition. His path through multiple G League and international teams has required him to adapt to varying roles, and he has consistently produced as a rebounding wing and secondary playmaker.
Notable Events and Milestones
Among the highlights of Stanley’s career are his selection to the ACC All-Freshman Team in 2020, his invitation to the 2021 NBA Slam Dunk Contest, and his continued presence on professional rosters across three continents. His debut 13-point performance against Kansas and his 22-point outing versus North Carolina stand out as signature college moments that announced his arrival on the national stage.

2025 Season Performance
The 2025 calendar year has been defined by movement across leagues. Stanley opened the year with the Valley Suns in the NBA G League before joining ESSM Le Portel of France’s LNB Pro A on April 9, 2025, a stop that gave him regular minutes in one of Europe’s most competitive domestic leagues.

Looking ahead, Stanley’s role with Šiauliai is expected to center on perimeter scoring, transition finishing, and defensive versatility as the club pushes through the LKL campaign. Continued health and consistency in Lithuania could open the door to extended European opportunities or a return to the NBA system in future seasons.
