WALTHAM — There are comings and goings on the Celtics staff these days, with assistant coach Darren Erman set to leave to become associate head coach for New Orleans under new leader Alvin Gentry. Also, Alex Barlow, who just completed a four-year playing career at Butler, is joining the C’s as assistant video coordinator.
Said director of player personnel Austin Ainge of Erman, “I know they are in discussions. I don’t know if anything’s final or what, but Erman’s a great guy, and if he does leave, we’ll miss him.
