Last summer, there wasn’t much to expect from Celtics President of Basketball Operations Brad Stevens approaching the 2025 NBA Draft. Boston entered the night with three late selections — No. 28, 46, and 57 — yet still managed to reel in a little-known prospect with the potential to impact winning more than most rookies in his class: Hugo González.
Stevens took González at No. 28 in a move that wasn’t regarded as noteworthy at the time, considering the organization had just traded away Kristaps Porziņģis to begin their roster overhaul. But Stevens had a vision for González from day one.
“He’s tough, he’s hard-playing, he cuts, he goes after the ball, he competes,” Stevens told reporters the following day after the first round. “He’s got all the intangibles of a winning basketball player. There’s things he can get better at, just like everybody else at that age, but competitiveness is at a high level.”
González was a unique case, joining the Celtics with more professional experience than most entering the NBA. Coming from Spain, fresh off three seasons with Real Madrid, González had already played alongside former NBA pros, including Serge Ibaka, Facundo Campazzo, Dennis Smith Jr., and Bruno Fernando. During his run in the Liga ACB, he rarely got minutes off the bench, buried behind Real Madrid’s veteran-loaded roster, which nearly slid González’s draft stock down to the second round.
It had nothing to do with his potential and everything to do with his limited sample size in Spain.
Stevens saw González as a spark plug capable of providing the Celtics with valuable minutes off the bench to maintain their intensity while starters rested. Stevens recognized González’s ability to make Real Madrid’s roster as a valuable prerequisite, speaking to the then-19-year-old’s ability to become a major rotation piece down the line if placed in the right development system.
Boston head coach Joe Mazzulla and his staff already checked off that box.
González, like many on the 2025-26 roster, was thrust into the spotlight. No Jayson Tatum for the first 62 games of the regular season meant it was up to everyone else to keep Boston’s ship from sinking. González had only logged 10.2 minutes through 69 games the previous year for Real Madrid, so there was an immediate pressure to perform whenever his open mic opportunities arrived.
On Oct. 24 against the Knicks at Madison Square Garden, González made his NBA debut and showed flashes, scoring six points with four rebounds, two steals, and one assist as Boston’s leader in plus-minus (+7). Teammate Jaylen Brown took notice of González’s motor and its ability to flip off and on at any moment, and suggested the Celtics “(needed) more of that.”
It wasn’t long before González earned the fan base’s approval, too.
The upside revealed itself from the start. González, unlike most rookies, didn’t need to score to keep himself on the floor. Mazzulla knew that through his defensive pressure to corner opposing offenses into compromising positions, possession after possession, González was a piece that needed time on the floor to flourish and develop. He earned that.
On Jan. 24 against the Nets, González committed a major defensive miscue, allowing Brooklyn’s Michael Porter Jr. to drain a wide-open 3-pointer. Immediately, Mazzulla sat González on the bench, which the young guard admitted was deserved. Later that same night, with 2.5 seconds left in overtime, González came off the bench in a desperation possession and nailed a clutch, game-tying corner 3-pointer to help secure a road victory in double overtime.
Little by little, González made it known that he wasn’t only a piece for the future, but also a piece ready to make a difference in real-time. He didn’t squander the opportunity to play in over 14 minutes across 74 appearances — including three starts — for the Celtics in his rookie campaign. Instead, González did everything to reward the team every chance he could.
On March 2, he accepted the challenge of guarding 6-foot-11 Giannis Antetokounmpo in just his third career start.
González rose to the occasion, with Brown and Neemias Queta sidelined, and set career-highs in points (18), rebounds (16), blocks (three), and steals (two). Tasked with the daunting defensive assignment of covering Antetokounmpo, he overcame the size mismatch and held his own — limiting the two-time MVP to just one made basket across five possessions.
Mazzulla recognized the performance as proof positive for both González and Stevens.
“This was them,” Mazzulla told reporters in Milwaukee. “I think Brad does a great job of finding guys with high competitive character. When you come into the locker room, you want to play for the guy next to you. You look for nights to create ownership and responsibility.”
González never obsessed over shot attempts or minutes. Even though the Celtics needed contributions wherever they could find them, he naturally let the game come to him. If a shot needed to be taken, he’d take it — only if necessary. If someone needed to rest, González was ready to carry the load. Everyone in the locker room and throughout the organization saw his potential from the start of Summer League, and watched as González used the regular season to build on that trust and solidify it.
González averaged 3.9 points, 3.3 rebounds, and shot 47.6 percent from the field in his rookie season. Defensively, he validated his upside. González averaged 0.6 steals and 0.3 blocks, registering a plus-minus that ranked third among rookies behind Kon Knueppel and Dylan Harper, netting González five second-place votes in the NBA’s All-Rookie Team.
In the playoffs, González didn’t get a chance to do anything — and that’s perfectly fine.
Boston is at a point where the coaching staff, locker room, and front office all have an idea of what they have in González. That’s critical. He’s graduated past the evaluation phase, as the Celtics no longer need to gauge his potential moving forward. González has obvious areas to refine this offseason, but his foundation is strong.
That’s more than most rookies can say, especially coming from Spain as a teenager, again rummaging for minutes behind proven professionals.
González belongs, and the C’s now know it.
“The reality is Hugo had a great rookie year and is, I think, a critical part of us moving forward because his athleticism can meet the moment in the big games,” Stevens told reporters during his end-of-season press conference. “That’s a real thing. You can see it. You know it. His strength is off the charts. He’s one of the strongest guys on our team now, pound-for-pound for a 20-year-old, so he’s got a bright future.”
