For 15 years, through championships and an unparalleled run of playoff berths and success, R.C. Buford and Gregg Popovich seemed to work as one brain. Popovich was the coach but also team president, Buford the GM, and together they built an NBA powerhouse.

Buford is moving on from that role. Or, more precisely moving up into a new management role, and assistant GM Brian Wright is taking over as GM, reports Jabari Young of The Athletic.

After a little more than 15 years serving as GM, Buford is getting prepared to bequeath the role to assistant GM Brian Wright, league sources have confirmed to The Athletic. Wright will report directly to Buford, who will officially get a new title that some around the NBA believe will be a role helping to oversee Spurs Sports & Entertainment. When the Spurs initially hired Wright in 2016, he stayed behind the scenes and focused mainly on scouting. But sources have informed The Athletic over the last year Wright has been more involved, even fielding calls and packages for the trade of Kawhi Leonard the previous summer.

Wright came to the Spurs from the Pistons a couple of years ago. That said, don’t expect a big change in how things are done in the Spurs front office. For one thing, Popovich is still there. Also, Wright has an excellent reputation around the league as being smart and a straight shooter. On top of all of that, Buford will remain his ultimate boss, although Buford’s role will change into one of more of a business manager for Spurs Sports & Entertainment.

Young hints there could be more changes coming. Obviously, the biggest would be when Popovich decides to step back in his dual roles as coach and president, but there could be shifts in the assistant GM ranks as well.

Just don’t expect the Spurs to stop being the Spurs.
