Celtics president of basketball operations Brad Stevens can’t speak about contracts publicly yet but he made one thing clear on Thursday at the Auerbach Center: He wants Jaylen Brown to stay in Boston.

Brown earned an All-NBA second team selection this season, which means that beginning on July 1, the Celtics have the opportunity to lock in their star to a five-year supermax extension worth about $295 million, which would start in the 2024-25 season. Asked if he would offer that extension, Stevens couldn’t answer directly but expressed his commitment to the two-time All-Star who he once coached.

“I’ve had nothing but great conversations with Jaylen, but we can’t talk about all that stuff,” Stevens said. “I’m not allowed to talk about A, the contract details, let alone the extension because it’s not of that time right now. His window is between July 1 and October or whatever it is. But I can say without a doubt, we want Jaylen to be here and he’s a big part of us and we believe in him and I’m thankful for him. …

“I’m really thankful for when those guys have success, they come back to work and when they get beat, they own it and they come back to work. So I know that’s what they’re about and that’s hard to find. … Those qualities, they aren’t for everybody. Jaylen had a great year, All-NBA year. He’s a big part of us moving forward in our eyes.”

Brown, after the Celtics’ Game 7 loss on Monday, said he’s unsure how contract extension talks will play out this summer when he was asked what his expectations were. It will be the biggest storyline of the Celtics’ offseason, especially given the uncertainty of Brown’s desire to stay in Boston long term after being non-committal about his future this season.

“I don’t even really know how to answer that question right now, to be honest,” Brown said. “My thought process is take it one day at a time, focus on getting better. Focus on what the future holds and see where we are from there. I guess I don’t know really know how to answer that.”
