Samuel David Hauser was born on December 8, 1997, in Green Bay, Wisconsin. He grew up in nearby Stevens Point, where basketball became a central part of family life. His father, Dave Hauser, served as an assistant basketball coach, providing Samuel with an early and immersive introduction to the sport.
At Stevens Point Area Senior High School, Hauser was a multi-sport athlete who also played golf and football. On the basketball court, he developed into a leading scorer and rebounder. As a junior, he averaged 18 points, 7.5 rebounds, and 3.3 assists per game, and he led the state with a 50.6 percent three-point shooting mark. That season he led SPASH 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.
As a senior, Hauser helped SPASH achieve an undefeated season and capture a second consecutive Division 1 state championship. He averaged 18.2 points, 6.7 rebounds, four assists, and 3.1 blocks per game, earning Wisconsin Gatorade Player of the Year honors and sharing Wisconsin Mr. Basketball recognition with teammate Trevor Anderson. On May 17, 2015, he committed to Marquette over Virginia, Iowa State, Creighton, and several other Division I programs.
Path to Basketball
Hauser’s path to the professional ranks began in earnest at Marquette, where he made an immediate impact as a freshman in 2016. He debuted on November 11, 2016, scoring 14 points off the bench in a win over Vanderbilt and earning Big East Conference Freshman of the Week honors. He reached a season-high 19 points in an 89–79 victory over Georgia and matched that mark twice more by February, finishing his freshman year averaging 8.8 points, five rebounds, and 1.3 assists per game while leading his team in minutes and defensive rebounding.
As a sophomore, Hauser raised his profile with a 30-point performance against Eastern Illinois and a seven-three-pointer outburst versus American. He averaged 14.1 points, 5.7 rebounds, and 2.9 assists, establishing himself as one of the Big East’s most productive wings. His junior season brought career highs of 31 points against Georgetown and 14 rebounds against Wisconsin, leading to All-Big East second team recognition before he announced his decision to transfer.
After sitting out a season under NCAA transfer rules, Hauser joined the Virginia Cavaliers for his senior year and averaged 16 points, 6.8 rebounds, and 1.8 assists per game. He posted a 50 percent field goal, 42 percent three-point, and 90 percent free throw shooting line, narrowly missing the thresholds for the prestigious 50–40–90 club.
