Just over three weeks before the Chicago Bulls are slated to begin preseason action, head coach Tiago Splitter has officially finalized his staff for his first year at the helm.

Splitter's group is a combination of new faces from around the league and holdovers from Billy Donovan's prior staff. Former Wizards head coach Wes Unseld Jr. headlines the group as the lone returning assistant coach from Donovan's tenure, while most of the remaining staffers are in the player development department.

Here's everything you need to know about the members of Splitter's 15-man staff of assistants:

Unseld Jr. is entering his third season with the Bulls after serving as Donovan's top assistant. He was a finalist for Chicago's head coaching vacancy before Splitter landed the job and filled in for Donovan for a single game this past February. Prior to joining the Bulls, Unseld compiled a 77-130 record over three seasons as the head coach of the Washington Wizards.

Blake Ahearn was among the first three assistants that Splitter hired to his staff in July, along with Rex Kalamian and Jonah Herscu. The 42-year-old coached the Austin Spurs to the G League Championship in 2018 and was most recently an assistant coach for the Memphis Grizzlies from 2020 to 2024.

The son of longtime NBA coach Nate McMillan, Jamelle McMillan has spent the last three seasons in the Pistons' organization. He was an assistant coach and player development coach for Detroit while leading the franchise's G League affiliate, the Motor City Cruise.

Kalamian has been an assistant coach for the Milwaukee Bucks for the last three years and has worked in the NBA since 1995. He is also the head coach of the Armenian National Team.

Splitter is bringing Herscu from Portland, where the two overlapped last year. Herscu was the head coach of the franchise's G League affiliate, the Rip City Remix, while Splitter was an assistant for the Trail Blazers and then eventually the interim head coach.

Former Bulls forward Taj Gibson is returning to the city that drafted him. After retiring as a player on Monday, the 41-year-old now has his first major coaching opportunity in Chicago, where he played seven-and-a-half seasons.

Martin Rancik is one of a few returners from the prior staff and is entering his seventh season with the Chicago Bulls. He began as a basketball operations associate in 2018-19 before spending two years as an assistant coach for the Windy City Bulls, and he's been a player development specialist since 2022. Rancik's new role is a promotion from his previous one.

Jordan Brink comes to Chicago after helping the New York Knicks win the 2026 NBA Finals as an assistant coach. He is widely regarded as one of the rising stars in the coaching ranks and garnered major praise from Knicks head coach Mike Brown during this postseason.

Pete Crawford returns for his fourth season as a player development coach in Chicago. He joined the Bulls in 2023 after seven seasons with the Dallas Mavericks, mostly as an assistant video coordinator.

LD Williams is entering his third season as a player development coach for the Bulls. The 38-year-old was an assistant coach for the G League's Long Island Nets before coming to Chicago in 2024.

Jeremiah Bonsu joined the Bulls as a senior video coordinator in 2024 and has been promoted to head video coordinator ahead of his third season with the organization. He worked alongside Splitter for the Houston Rockets during the 2023-24 season.

Micah Burno received his first NBA opportunity as a video intern for Chicago in 2023 and spent two years with the Windy City Bulls. He became a video coordinator last year and has been promoted after one season in the role.

Brandon Leftwich has spent the last four years in the G League, working with the Wisconsin Herd and Raptors 905. He went from an assistant coach in Toronto to a video coordinator with the Chicago Bulls, his first job at the NBA level.

A Chicago native, Delvon Johnson was most recently a basketball operations assistant for the Greensboro Swarm, which won the 2026 G League Championship. He played professional basketball overseas from 2011 to 2025.

The son of Hall of Fame wing Penny Hardaway, Jayden Hardaway played for his father at the University of Memphis from 2019 to 2024. He played for the G League's Capital City Go-Go in 2024-25 and now joins Splitter's coaching staff.
