Michigan announces four-member 2026 signing class: What Dusty May said about each signee

Michigan Wolverines basketball head coach Dusty May has signed a four-man class during the early signing period for the 2026 cycle. The program announced the additions in an official press release Friday morning, saying that each athlete signed a Big Ten Scholarship Agreement.

Michigan has added Boston (Mass.) The Newman School four-star power forward Quinn Costello, Gainseville (Fla.) The Rock School four-star shooting guard Joseph Hartman, Knoxville (Tenn.) Catholic three-star small forward Malachi Brown and center Marcus Moller out of Unicaja Malaga in Denmark.

“This class fits everything we value — versatility, intelligence and competitiveness,” the Michigan head coach said in a release. “Each of them enjoys playing for their teammates, embraces coaching and wants to be part of something bigger than themselves. They all bring different strengths, but the common thread is their character and work ethic.

“They understand what it means to represent Michigan, and they’re ready to put in the daily effort to grow on and off the court. We’re excited about their potential and how they’ll elevate our culture. This group is the foundation of what we’re building for the future.”

Costello is the crown jewel of the class, checking in as the 32nd-best player in the nation according to Rivals, but Hartman isn’t far behind (No. 63, Rivals).

The Wolverines’ 2026 class currently ranks No. 26 in the country and No. 6 in the Big Ten, according to the Rivals Industry Rankings.

Here’s what May and the Michigan program said about each prospect in a press release:

PF Quinn Costello

As a junior (2024-25), Costello came off the bench and averaged 6.9 points and 3.4 rebounds, helping Newman win the NEPSAC-AAA title. That summer, he broke out on the Under Armour Circuit with the Middlesex Magic, averaging 11 points and five rebounds. His standout performance at Pangos All-American Camp earned him co-Most Outstanding Player honors.

“Quinn is a floor general,” Michigan’s head coach said. “He plays with great command and confidence, and his voice carries through the team. He’s a strong decision-maker who understands tempo, spacing and how to put teammates in successful positions. He combines toughness with feel. He’s not afraid to make the extra pass or take a big shot when it matters.

“His competitive nature and basketball IQ make him a perfect fit for how we want to play. What we love is that Quinn loves the process — film, lifting, reps. He’s wired to improve every day, and that mindset will serve him and our program extremely well.”

SG Joseph Hartman

Hartman continued to elevate his game during the 2025 summer season with Austin Rivers SE Elite, averaging 13.8 points, 4.6 rebounds and 2.2 assists in Adidas 3SSB play.

As a junior (2024-25), he led The Rock in scoring and helped the team reach the national quarterfinals, averaging 19 points, six rebounds and three assists. He recorded a pair of 29-point games and previously helped The Rock win the 2024 SIAA State Championship as a sophomore. At the 2024 Adidas All-American Camp, he averaged 11.7 points, 4.0 rebounds and 2.7 assists with Team Minnesota Timberwolves.

“Joseph brings versatility and motor,” May said. “He’s a big who runs the floor hard, rebounds outside his area, and embraces contact. He has a great touch and an instinct for positioning — both offensively and defensively. He’s continued to add strength and confidence in his perimeter game, and we see real potential for growth there.

“His energy and competitiveness lift everyone around him. Joe’s also a connector — he’s humble, hard-working and fully invested in the team. He’ll be a guy who earns respect the moment he steps on campus.”

C Marcus Moller

Moller, an emerging international talent, will match current Wolverine Aday Mara as the tallest player in program history. The Danish center plays in Spain for Unicaja Malaga U22 and has captained Denmark’s junior national teams. He comes from Espergærde, a coastal town near Copenhagen and close to the Swedish border.

At the 2024 U18 EuroBasket, he led Denmark in points (13.1), rebounds (7.4), blocks (1.7) and minutes (28.1), recording four double-digit scoring games. He has also competed in early rounds of the 2027 FIBA European World Cup Qualifiers, averaging nearly four points and three rebounds.

This season with Unicaja U22, he is the team’s lone non-Spanish player and leads the league in blocks while ranking fourth in rebounds. Through five games, he is averaging 13.4 points, 9.6 rebounds, 1.6 assists, 0.8 steals and 2.2 blocks in 30.8 minutes. His early highlights include two double-doubles, a 19-rebound performance and a 21-point outing.

“Marcus is a connector,” May said. “He plays for his teammates, talks on defense and embraces preparation. He really plays with a poise beyond his years. He can handle, pass and shoot, and he processes the game quickly, which fits our pace-and-space style. He is comfortable making simple plays, stretching the floor, and guarding multiple positions.

“With his length and shooting touch, we believe he can contribute early while still having a high ceiling in our system. Most importantly, he’s about the right things: work, humility and team. He’s coachable, detail-oriented and relentless in his daily habits. He’ll thrive in Ann Arbor because he values development and the student-athlete experience.”

SF Malachi Brown

He began his career at Roane County High School before transferring to Knoxville Catholic for his senior season. As a junior (2024-25), Brown averaged 11.3 points, 6.1 rebounds, 2.1 steals and 1.2 blocks while helping Roane County to a 27-5 record. In the summer of 2025, he shined for the Tennessee Impact on the Adidas 3SSB Circuit, posting 15.3 points, 4.5 rebounds, 2.5 assists and 1.3 steals per game, earning third-team honors at the event.

“Malachi is a dynamic athlete who plays with explosiveness and edge,” the Michigan head man explained. “He has the quickness and strength to pressure the ball defensively and get downhill on offense. His ability to guard multiple positions and finish through contact gives us a lot of lineup flexibility.

“He’s developing as a playmaker and shooter, and he’s already shown he can impact winning in different ways. Malachi’s presence on the floor changes the game. He plays with emotion and passion that energizes everyone. He’s built for our culture — tough, competitive and team-first.”
