‘All of those things mattered': Inside Neemias Queta's breakout with Celtics originally appeared on NBC Sports Boston
Neemias Queta’s NBA future was murky at best when the Sacramento Kings cut him in September of 2023.
The Boston Celtics, despite an overstocked frontcourt that would soon deliver the franchise’s 18th title, were convinced they could mold Queta into the sort of player who could aid a championship quest.
“They told me right away, like, ‘OK man, you’re here, we’ve got these guys ahead of you, they’re really good, and you can become one of them. But you’ve got to put in the work,’” said Queta. “We’ve got to put you through these situations where we can develop you and try to get the best version of yourself.”
A dramatic frontcourt overhaul this past summer cleared a pathway for Queta to elevate to a starting role. But it was Queta’s relentless desire to improve, including over the course of the 2025-26 season, that confirmed Boston’s decision and helped Queta emerge as one of the best value contracts in the league.
On Friday, the NBA will announce the winner of this year’s Most Improved Player. Queta is not one of the three finalists — Atlanta’s Nickeil Alexander-Walker, Portland’s Deni Avdija, and Detroit’s Jalen Duren will vie for the honor — but Queta should slot somewhere close behind that trio.
Queta and the Celtics have more pressing issues, anyhow. Queta’s postseason performance could play a major role in the length of Boston’s playoff stay.
Joel Embiid — the league’s reigning MVP at the time Sacramento cut ties with Queta — returned to Sixers practice on Thursday and soon could be back in game action. If the Celtics outlast Philadelphia in Round 1, Queta might be tasked with defending the likes of New York’s Karl Anthony Towns and Mitchell Robinson or Cleveland’s Evan Mobley and Jarrett Allen — or maybe get his own MIP showdown with Duren.
It’s crazy to think that, less than three years ago, Queta wasn’t certain what the next step in his NBA journey would be. The Celtics were certain they could tap into his potential.
“From that point on, it was just a matter of putting in the work, being in the lab, watching film,” said Queta. “And, honestly, I think the structure made my life so much easier. And the setup from workouts every day, we were doing individual work, the film sessions as a group, the individual film sessions, [coach] Joe [Mazzulla’s] attention to detail, too — all of those things mattered.”
Mazzulla said it was a series of spot starts that Queta made last season when Celtics’ veteran big men were resting that helped Queta earn the trust of the coaching staff. After Al Horford, Kristaps Porzingis and Luke Kornet all departed this offseason, Mazzulla made sure Queta knew he was going to be the starting big man for the 2025-26 Celtics.
“We had guys out [last season] and he won a game for us,” said Mazzulla. “There’s been a bunch of times where Al or KP had sat, or guys were out, and Neemi played, and the minutes that you give are so impactful. And I thought it was important to empower him to be the starting center of the Celtics after what he did for us over the last couple years in Maine, [and] in those games where guys are out. And he’s taken that responsibility and ownership very seriously.”
Queta and Mazzulla huddled early in the summer of 2025, and Mazzulla laid out the plan to elevate Queta to a starter.
Get your mind right. You have to figure it out. I don’t want to hear any s—.

“We went to dinner and we just chopped it up for a couple hours, and it was pretty special,” said Queta. “When we had that conversation, it was more about, ‘OK Neemi, you know what’s going on. You know what’s going to be ahead of you for the future. Make sure you get ready. Do your thing, work as hard as you can, but be prepared, because it’s a different level of expectancy, [and] it’s a different level of responsibility as well.’ So, knowing that I’d be counted upon every night to deliver was huge for me, knowing that the season was going to be big for us.
“My ability to go into the summer, knowing every day that I’d be counted on, and just going out there working as hard as I could, just opened up the mindset for me to come in every night and deliver.”
Mazzulla pulled no punches with his advice for Queta.
“Get your mind right. You have to figure it out. I don’t want to hear any s—,” Mazzulla said of his instructions after naming Queta starter. “I’m telling you now so that by the time the season starts, you have an understanding of what the expectation is, what we need from you.
“Credit to him, he cares, he wants to get better, pushes himself. He’s really quiet, so you don’t get to see the competitive mindset that he really has on wanting to get better and get it right, but he cares, man. He’s good.”
Queta just wants to do all the dirty work to aid winning. He jousts with bigs and hunts rebounds. He finished second in the NBA in screen assists (274) and screen-assist points (668), trailing only Minnesota’s Rudy Gobert in both categories.
Queta owned the best net rating in the entire Eastern Conference (minimum of 50 games played and 25 minutes per game) as the Celtics outscored opponents by 13.2 points per 100 possessions in his floor time. (Duren was second at +11.8). Queta also had the best defensive rating in the East at 105.6 (second: Detroit’s Ausar Thompson at 107.2).
Queta ranked 18th in ESPN’s new Net Points metric that uses box score data to quantify a player’s two-way impact. Queta finished third overall in Defensive Net Points, trailing only San Antonio’s Victor Wembanyama and Oklahoma City’s Chet Holmgren. Wembanyama was the Defensive Player of the Year, while Holmgren finished second in the voting.
Queta doesn’t take the opportunity for granted and just wants to keep improving.
“It’s surreal still to me, being able to find my way in this league, finding a place where I’m believed in, a coach that trusts me and wants the best for me, is just huge for me,” said Queta. “And I want to come out here and do my best to deliver.”
Queta doesn’t need a Most Improved trophy to know just how far he’s come.
