Over the last few years, the Boston Celtics have seen some serious attrition on their NBA coaching staff. 

Of course, the team let former head coach Ime Udoka go for non-basketball reasons after the 2021-22 campaign, and then they lost assistant Will Hardy to the Utah Jazz before the 2022-23 campaign. Fast forward to 2023-24 when the Celtics won the NBA championship but lost assistant Charles Lee after the title run: He became the head coach of the Charlotte Hornets.

And now the Celtics could be on the verge of losing another assistant: 34-year-old Tyler Lashbrook is reportedly one of five finalists for the Portland Trail Blazers head coaching opening. As reminded by Zack Cox of the Boston Herald, Lashbrook was the head coach of the G-League's Maine Celtics in 2024-25 before coming back to the NBA this past season.

He helped the Celtics go 56-26 and earn the No. 2 seed in the Eastern Conference playoffs, but they were eliminated in the second round by the Philadelphia 76ers.

In addition to being on the bench with the Celtics, the Kentucky native also worked in player development for the Celtics from 2023-24. Before that, was with the 76ers from 2018-23.

He attended college at Western Kentucky from 2010-14.

The team placed Chauncey Billups on indefinite leave after an investigation tied him to illegal poker games and gambling rings. There was no word that he was ever officially fired, but given that the team is going through a coaching search, that appears to be the case.

Billups is a Basketball Hall of Famer.

Under interim head coach Thiago Splitter, the Blazers went 42-40, earning the No. 7 spot in the Western Conference playoffs. They were beaten by the San Antonio Spurs in the first round and the Spurs are still playing in the Western Conference Finals.

--The NBA has agreed to sweeping changes to the NBA's Draft Lottery process, aimed at hurting "tanking" teams. The Celtics don't aspire to have to have to care about the draft lottery any time soon, but here's what's happening. 

--Speaking on Wednesday as part of a radio segment on ESPN Cleveland, ESPN NBA Insider Brian Windhorst said he hasn't heard any real trade traction involving Giannis Antetokounmpo and the Celtics. Those comments were mirrored by Chris Haynes, who spoke on Sirius XM as well. The Bucks should have a resolution by the start of the draft on June 23.
