For the first time since we began taking an annual look at the NBA’s longest-tenured head coaches a decade ago, Gregg Popovich‘s name doesn’t sit atop the list.
The longtime Spurs head coach had been on the sidelines in San Antonio for nearly three decades, having taken over coaching duties in December 1996. However, he gave way to assistant Mitch Johnson last November after suffering a stroke and then announced this spring that he had decided to end his coaching career at age 76.
Popovich retires from NBA coaching as the league’s all-time leader in regular season wins (1,390) and overall victories (1,560). He was also the oldest coach in league history and was the NBA’s longest-tenured coach by over a decade.
The shake-up at the top of our list starts with Popovich, but definitely doesn’t end there. In total, four of the NBA’s six longest-tenured head coaches have been replaced since we checked in last summer, with Michael Malone of the Nuggets (June 2015), Taylor Jenkins of the Grizzlies (June 2019), and Tom Thibodeau of the Knicks (July 2020) having been dismissed by their respective teams in recent months.
While the total number of coaching changes in the past year – six – isn’t abnormally high, it’s unusual for us to be removing so many names at the top of our list.
With all that in mind, here’s the current breakdown of the NBA’s longest-tenured head coaches by team:

Spoelstra is the new name at the top of the list of longest-tenured coaches, with a comfortable six-year margin between him and second-place Kerr. Incredibly, the gap of six-plus years between Kerr and third-place Donovan is larger than the gap five years between Donovan and Brown, the head coach most recently hired.
In other words, Spoelstra and Kerr are now the only coaches in the NBA who have been with their respective teams for longer than five years, which is a testament to just how difficult it is for a head coach to stick in one place.
Steve Kerr has been the worst HC in the NBA since 2023. Name any other HC who can get away with literally admitting they are bad at developing players and cannot even install plans to do so with lottery picks.
Moses Moody had a 30 point game when he was 19? Bench him for 4 years! – Kerr
Having a difficult time wrapping my head around it’s only been five years Donovan has been coaching the Bulls.
Not a lot of job security as NBA HC. Over half (16) have two years or less on the job.
2 things hit me about this list…
1… Bulls fans have to be irate…
2… Timberwolves fans must feel weird to be a picture of stability…
Wow. Davey J, self-proclaimed Warriors Superfan, in his daily “I hate Steve Kerr” rant, says that Moses Moody has been on the bench the past 4 years. Funny. How did Moody accumulate 57 starts and 4200+ career minutes played?
