The Cavaliers reshaped the top of their basketball operations department from within, promoting Brandon Weems to general manager and expanding the roles of Jon Nichols, Brendon Yu and José Calderón. The club also brought in Dashiell Flynn as chief technology officer of basketball operations, with each move effective immediately.
Weems, an Akron native who began with Cleveland as a scout in 2015, steps into the GM chair after 11 seasons in the organization. His last four years came as an assistant general manager, following a season as senior director of player personnel and four years directing the scouting department from 2017 through 2021.
His new portfolio puts Weems at the center of the roster-building calendar: managing the roster, handling contract negotiations, overseeing domestic and international scouting, and supervising the club’s daily basketball operations work. He will remain alongside president of basketball operations Koby Altman through the draft cycle, including prospect evaluations, rankings, background work and statistical review.
Altman said Weems’ long record in player evaluation and team construction made him ready for the larger assignment. He pointed to the continuity created by elevating leaders already familiar with the Cavs’ culture and internal processes, while giving each executive more authority in his area.

Nichols moves up to associate general manager after four seasons as vice president of basketball strategy. He joined Cleveland before the 2013-14 season as director of analytics, later spending a year as senior director of strategy and research before taking his most recent post.
He has led the club’s data strategy while contributing to cap and roster decisions, free-agency and contract talks, trade-planning work, long-range operational preparation and collective bargaining agreement applications. As associate GM, Nichols will also take a larger role in building on-court strategy models and new analytical approaches, while continuing to refine the organization’s player-value and draft models.
Yu, now entering his 11th season with the franchise, becomes an assistant general manager after a wide-ranging run through Cleveland’s scouting and developmental pipeline. He was general manager of the Cleveland Charge from 2019 through 2023, with the Cavaliers adding director of college scouting to his responsibilities before the 2022-23 campaign. He previously served as director of G League operations and basketball operations special projects after starting as a seasonal basketball operations assistant in 2014-15.
As director of scouting, Yu led evaluations across college, international and G League talent while overseeing personnel work for the Cavaliers. During his Charge tenure, 16 players received NBA call-ups, including current Cleveland guard Sam Merrill. The Charge finished 30-20 in 2022-23 and reached the G League playoffs for the first time since 2016-17.
Calderón also receives an assistant general manager title. The former NBA guard returned to the organization in 2022 as a special advisor to the front office and has worked across basketball and organizational initiatives, including the Cavaliers’ 2026 training camp at The Embassy in Andalusia.
Before returning to Cleveland, Calderón worked for the National Basketball Players Association as special assistant to executive director Michele Roberts, helping senior union leadership on strategy and issues affecting active players. His 14-year NBA playing career covered seven teams and included Cleveland’s run to the 2018 NBA Finals.
Flynn arrives from Amazon Web Services, where he had worked in machine learning and sports strategy since 2018 and most recently held the title of global head of AI for sports. His task with the Cavaliers will be to develop and integrate new basketball operations technology, while creating the infrastructure and governance needed for the department’s broader projects. Flynn brings more than two decades of experience across technology, government, consulting and strategy work, including time at Accenture.
