Early Life and Background
Samuel David Hauser was born on December 8, 1997, in Green Bay, Wisconsin, USA. He grew up immersed in basketball, with his father Dave serving as an assistant basketball coach at Stevens Point Area Senior High School. Hauser attended Stevens Point Area Senior High School, known as SPASH, in Stevens Point, Wisconsin, where he played basketball, golf, and football. His younger brother, Joey Hauser, was one of his teammates for his final two years of high school.
As a junior at SPASH, Hauser averaged 18 points, 7.5 rebounds, and 3.3 assists per game while leading the state with a 50.6 three-point percentage. He guided his team to a 27-1 record and the Wisconsin Interscholastic Athletic Association Division 1 state championship, scoring 25 points in the title game against Germantown High School. During his senior season, Hauser helped SPASH achieve an undefeated season and win a second consecutive Division 1 state championship. He averaged 18.2 points, 6.7 rebounds, four assists, and 3.1 blocks per game that year. His exceptional performance earned him Wisconsin Gatorade Player of the Year honors and co-Wisconsin Mr. Basketball recognition, which he shared with his teammate Trevor Anderson.
On May 17, 2015, Hauser committed to play college basketball for Marquette University, choosing the Golden Eagles over offers from Virginia, Iowa State, and Creighton, along with several other NCAA Division I programs. His decision marked the beginning of a college career that would span two major conference programs.
Path to Professional Basketball
Hauser made his debut for Marquette on November 11, 2016, scoring 14 points in 19 minutes off the bench in a 95-71 victory over Vanderbilt. He was named Big East Conference Freshman of the Week and averaged 8.8 points, five rebounds, and 1.3 assists per game as a freshman while shooting 45.3 percent from three-point range, leading his team in minutes and defensive rebounding. His sophomore season brought a significant scoring jump to 14.1 points per game, with season highs of 30 points in overtime wins and 29 points on a career-high seven three-pointers in a single game. As a junior, Hauser was joined at Marquette by his brother Joey and posted career-highs in rebounding with 14 against Wisconsin and 31 points in a victory over Georgetown, earning Second-team All-Big East honors after averaging 14.9 points and 7.2 rebounds per game.
Following his junior season, Hauser announced his transfer from Marquette to Virginia, seeking what he described as a better fit. He committed to Virginia on May 28, 2019, and sat out the 2019-20 season due to NCAA transfer rules. In his debut for Virginia on November 25, 2020, he scored 19 points in an 89-54 win against Towson. As a senior during the 2020-21 season, Hauser averaged 16 points, 6.8 rebounds, and 1.8 assists per game while posting an exceptional 50% field goal percentage, 42% three-point percentage, and 90% free throw percentage. He came up just .004 short in free throw percentage from officially qualifying for the exclusive 50-40-90 club. Alongside teammate Trey Murphy III, who also qualified that season, Hauser came close to making history as the first two teammates to reach the 50-40-90 club at the NCAA men’s basketball level simultaneously. He was named First-team All-ACC in 2021 and declared for the 2021 NBA draft.
Samuel David Hauser Career
Early Career (2021–2023)
Hauser went undrafted in the 2021 NBA draft but quickly found an opportunity, signing a two-way contract with the Boston Celtics on August 13, 2021. The deal allowed him to split time between the NBA roster and the Maine Celtics, Boston’s G League affiliate. He made his NBA debut on November 20, 2021, scoring points in a 111-105 victory over the Oklahoma City Thunder. On February 11, 2022, his two-way contract was converted into a standard NBA contract. During his rookie season, the Celtics reached the 2022 NBA Finals but lost to the Golden State Warriors in six games despite holding a 2-1 series lead. On July 3, 2022, Hauser re-signed with the Celtics on a three-year, $6 million deal, signaling Boston’s confidence in his development as a reliable three-point threat and rotational piece.
NBA Breakthrough (2023–2024)
During the 2023-24 regular season, Hauser’s role expanded significantly, and he emerged as a trusted floor spacer for a Celtics team loaded with offensive firepower. He contributed five dunks across eighteen games, earning the affectionate nickname Slam Hauser from fans and teammates after a standout performance in a 126-97 win over the Utah Jazz on January 5, 2024. His shooting consistency and ability to stretch defenses created open driving lanes for Boston’s stars. On March 17, 2024, Hauser recorded a then-career-high 30 points on a then-career-high 10 three-pointers made in a 130-104 victory over the Washington Wizards, announcing his arrival as a genuine offensive weapon.
Hauser helped the Boston Celtics capture the 2024 NBA championship, where they defeated the Dallas Mavericks in five games. Throughout the Finals, he contributed 11 three-pointers across the series, providing the perimeter shooting that Boston relied upon to stretch the Mavericks’ defense. His three-point shooting proved especially valuable in the Celtics’ offensive scheme, creating the spacing that allowed teammates to operate effectively in the paint and off-ball cuts. The championship run cemented Hauser’s status as a key contributor on one of the league’s elite teams.
Boston Celtics Era (2024–Present)
On July 21, 2024, Hauser signed a four-year, $45 million contract extension with the Boston Celtics, rewarding his development into a reliable rotation player and championship contributor. The deal locked him in with the team through the 2028 season and represented a significant commitment from Boston to a player who had gone from undrafted free agent to NBA champion. Entering the 2024-25 season with a newly secured contract, Hauser continued to build on his established role as one of the Celtics’ most dependable three-point shooters.
On March 10, 2025, Hauser delivered one of the finest performances of his career, scoring a then-career-high 33 points, including nine three-pointers, in a 114-108 victory against the Utah Jazz. In a remarkable third quarter, Hauser made seven three-pointers, setting a Celtics franchise record for the most three-pointers made in a single quarter. By accomplishing this feat, Hauser became only the eighteenth player in NBA history to make seven or more three-pointers in one quarter, placing himself among an elite group of shooters in league history.
Shooting Style and Strengths
Hauser is primarily valued for his elite three-point shooting and ability to space the floor at the NBA level. Standing at 6 feet 7 inches, he presents a matchup challenge for opposing defenders due to his size combined with his quick shooting release. His catch-and-shoot proficiency makes him a constant threat when moving off the ball, and his off-ball movement allows him to find open looks within Boston’s motion offense. While he earned the Slam Hauser nickname for his above-the-rim finishes and dunks, his primary value to the Celtics comes from his perimeter shooting, which consistently forces defenses to stretch and creates driving lanes for teammates such as Jayson Tatum and Jaylen Brown.
Notable Events and Milestones
Hauser’s March 2025 performance against the Utah Jazz stands as the defining individual achievement of his NBA career. His seven three-pointers in the third quarter set a Boston Celtics franchise record and placed him among just 17 other players in NBA history to accomplish that single-quarter feat. Earlier in his career, he hit a game-tying three-pointer with three seconds remaining against the Milwaukee Bucks on February 14, 2023, sending the game to overtime in what became a memorable regular-season moment. His 2024 NBA championship remains the pinnacle team accomplishment of his professional career, with his 11 three-pointers across the Finals demonstrating his value on the biggest stage.
