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 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.”

What’s next for Grant?

It was certainly an interesting season for Grant Williams, who did not come to terms with the Celtics on a new contract in October before what became a bumpy and frustrating season for the fourth-year forward.

Williams started the season strong, but fell out of favor and out of the rotation during the second half. After becoming such an important player in his first three seasons, his minutes were never guaranteed as the playoffs began but seemed to come through whenever he was given an opportunity. He eventually earned some trust back and was key for the Celtics as they fought back to even the Eastern Conference Finals. But his future with the franchise remains cloudy entering the summer.

Williams will be a restricted free agent, which means the Celtics can match any offer he gets from another team. It’s unclear exactly how much he could command after an up-and-down season – earlier this season, it was reported Williams will seek a deal that will earn him around $20 million per season – but he could certainly depart if the C’s aren’t willing to pay up for him.

“Grant’s a good player,” Stevens said. “Grant has been a good player. I can’t talk about, as you know, with Jaylen, Grant, or whoever, I can’t talk about details of contracts and specifically with Grant’s own restricted free agency, all those are down the road right now as far as when we can discuss those things with him or with you. But he is a good player who was on a really deep team. And with that, with the addition of (Malcolm) Brogdon last year, that was going to require that guys that had gotten a little bit more opportunity weren’t going to get as much. And that obviously hit a few of our players, Payton (Pritchard) included, and Grant was another one of them.

“But everybody around the league knows that Grant can add value to a winning team. We know that. We’re big fans of his and I thought he played, did a lot of good things when he got the opportunity. But I don’t think it was an easy roster to always decide who would play because we did have a lot of good players.”

Limping to the finish

Malcolm Brogdon, who suffered a partial tear of a tendon in his right forearm, was a shell of himself in the Eastern Conference Finals and acknowledged he may need surgery this offseason. That determination hasn’t been made yet.

“We’re going to put our heads together and he’ll put his head together with his agent and figure out what he wants to do with regard to next steps,” Stevens said.

Jayson Tatum suffered a left ankle sprain on the first play of Game 7 and was nowhere close to himself. He played through the injury as he logged 42 minutes and scored just 14 points. Stevens said he was doing “a little bit better.” Stevens said Derrick White suffered just a hyperextension and small sprain in his right knee in Game 7 that forced him out in the fourth quarter.

Stevens didn’t want to make excuses for the sudden injury toll the Celtics took to end their season.

“We had a number of guys by the end, but probably no more than every other team does,” Stevens said. “So certainly not excuses. … We’ve got a couple of other things that we’ll have to address and look at here moving forward, but that’s no different than anybody else that plays till May 29 or whatever.”
