The coaching carousel is spinning, and another familiar face from the Boston Celtics' bench is getting a shot at the big chair. Ben Sullivan, a 42-year-old Boston native and former Celtics assistant, has reportedly interviewed for the Portland Trail Blazers' head-coaching vacancy.

Sullivan, who served as an assistant in Boston from 2021 to 2023, is making his second consecutive offseason push for a top job. According to HoopsHype senior NBA insider Michael Scotto, the Blazers brought him in for discussions after he also interviewed for the Phoenix Suns' head-coaching position last summer.

What makes Sullivan an intriguing candidate? He's been a coaching chameleon, learning from some of the league's best minds. He spent time under Ime Udoka in both Boston and Houston, worked with Joe Mazzulla during the Celtics' recent resurgence, and cut his teeth alongside Mike Budenholzer in Milwaukee and Atlanta. That's a résumé that blends championship pedigree with modern NBA strategy.

Before returning to the Rockets—where he now works alongside Udoka—Sullivan was part of Boston's coaching staff that helped guide the team to the 2022 NBA Finals. His journey also has a local connection: he played college ball at the University of Portland, giving him a natural tie to the Pacific Northwest.

For Blazers fans hoping for a fresh direction, Sullivan represents a new-school thinker with deep roots in winning cultures. And for Celtics fans watching from afar, it's another reminder that Boston's coaching tree continues to branch out across the league.
