Road to Duke
Kon Knueppel II was born August 3, 2005, in Milwaukee, Wisconsin, into a house with six basketball hoops scattered around the property. His father, also named Kon, had scored 2,064 career points at Wisconsin Lutheran College — the school’s all-time leading scorer — and was a four-time All-Lake Michigan Conference selection. His mother, Chari Nordgaard Knueppel, had scored 1,964 career points at the University of Wisconsin-Green Bay — the program’s all-time leading scorer. She was an All-Horizon League member every season, played in two NCAA Tournaments, played professionally in Greece, and was inducted into UW-Green Bay’s Hall of Fame in 2004. Her number 33 was retired in January 2025 during a ceremony she flew in for between her son’s Duke games.
The basketball bloodlines ran deeper than even Kon and Chari. Chari’s brother, Jeff Nordgaard, starred at UW-Green Bay before being drafted by the Milwaukee Bucks in the second round in 1996. He played 13 NBA games and spent thirteen years playing professionally overseas. Chari’s maternal grandfather, Arthur “Bud” Rose, played basketball at North Carolina State in 1931–32 and earned Honorable Mention All-American honors — the first All-American in NC State history. The Knueppel-Nordgaard family tree reads like a basketball encyclopedia stretching back nearly a century.
On Kon’s father’s side, there were the uncles: Klint, Klay, and Kole. They competed alongside Kon Sr. in the Gus Macker 3-on-3 Basketball Tournament as a team called the “Flying Knueppel Brothers” — having rejected the alternative name, “Free the Knueppel.” Uncle Kole became a college football referee in the Big Ten.
Kon is the oldest of five boys. His brothers, in order: Kager, Kinston, Kash, and Kidman. All five play basketball. When Kon committed to Duke in November 2023, he posted a photo on Instagram of himself and his four younger brothers standing inside the Duke locker room. Each boy was holding one of Duke’s five national championship trophies. Five brothers. Five trophies.
But here is the part nobody expects. When Kon was five and six, he was not into sports at all. His uncle Jeff Nordgaard, the former NBA player, remembers being surprised. Little Kon was bookish, using vocabulary beyond his age. The family was starting to think he might be a non-athlete — and then his parents bought a Nintendo Wii. It was the family’s first video game console. Kon played Wii Sports basketball obsessively. The virtual game awakened something. His parents enrolled him in a kindergarten league. He didn’t score a single point in his first ten games. He ducked when teammates passed him the ball. The all-time leading scorers at Wisconsin Lutheran College and UW-Green Bay had produced a child who couldn’t catch a bounce pass.
Kon Sr. ran a men’s league in Milwaukee — had been running it for twenty years. In eighth grade, Kon II started playing in it. Among the regulars: Ben Brust, a former Wisconsin Badger and the program’s all-time three-point leader. Brust kept beating Kon on backdoor cuts. By senior year, Kon was the one doing the cutting. The men’s league taught him what no AAU circuit could.
Chari ran a daycare from the family home since 2006. Kon Sr. worked as a school counselor in Milwaukee public schools. Six hoops on the property. Five boys. Two parents who were all-time leading scorers. Blue-collar Milwaukee.
At Wisconsin Lutheran High School: 10.8 PPG as a freshman, 19.7 as a junior, 26.4 as a senior. Perfect 30–0 record, WIAA Division 2 State Championship. Wisconsin Mr. Basketball. Gatorade Wisconsin POY. Also played baritone in the school band. He chose Duke because: “I want to play against the best players every day in practice, because that will make me better.” Enrolled June 2024. Roommate: Cooper Flagg.
At Duke
Knueppel started all 39 games as a freshman — tying Duke’s single-season record for starts by a freshman. 14.4 PPG, 4.0 RPG, 2.7 APG. Shot 47.9% from the field, 40.6% from three, and 91.4% from the free-throw line — highest FT% in the ACC, second-highest by a Duke freshman in history (only J.J. Redick shot better). Made 38 consecutive free throws from February through March.
Cooper Flagg was the headliner. Knueppel was the other half. Flagg was impossible to keep out of the lane. Knueppel was a lethal shooter who made the high-IQ plays he’d learned from years in his father’s men’s league. Scheyer: “Their personalities were perfect for each other — competitive, unselfish, and smart.”
One preseason practice, Flagg didn’t have his best stuff. The guy who called him out? Knueppel. He told the future number-one pick to get his head in the game. Scheyer’s staff still points to that moment.
Then the ACC Tournament. Flagg sprained his ankle in the quarterfinal and missed the rest. Knueppel stepped into the spotlight: 21.0 PPG, 5.7 RPG, 4.7 APG across the tournament. 18 points and 8 rebounds in the title game against Louisville. ACC Tournament MVP. Nobody cheered harder for him than Flagg on the sideline.
The same week, back in Wisconsin, brother Kager scored 10 points in the WIAA Division 1 state title game. Wisconsin Lutheran won back-to-back championships in a higher division. Mother Chari flew between Raleigh and Madison, refusing to miss a game from any son. She attended every Duke game in person that season. Every one.
NCAA Tournament: 20.5 PPG in the Sweet 16 and Elite Eight. 16 points in the Final Four against Houston. East Region All-Tournament Team. Season line: 84 three-pointers, 117-of-128 free throws, and the quiet, lethal efficiency that made every scout say: this kid is going to play in the NBA for a long time.
After Duke
Charlotte selected Knueppel 4th overall in the 2025 NBA Draft. On draft night, Cooper Flagg was mid-interview on NBA TV when the pick was announced. Flagg shot out of his seat — the most animated he’d been all evening, including when his own name was called first. The former roommates, the freshman duo who pushed each other every day, were both top-five picks.
Knueppel led the Hornets to the 2025 NBA Summer League championship, scoring 21 in the title game. Summer League Championship MVP. Regular-season debut October 22: 11 points and 5 rebounds vs Brooklyn. By early November: a 30-point game against Miami, Eastern Conference Player of the Week nomination. On November 14, he scored 32 in an overtime loss against Milwaukee — his hometown team, the franchise his uncle Jeff had once played for — hitting two late threes to force OT. Averaging 19.2 PPG, 5.5 RPG, 3.4 APG. Alongside Flagg, the two former roommates are frontrunners for NBA Rookie of the Year.
Where Is He Now
Kon Knueppel is 19 years old. He plays for the Charlotte Hornets. His former roommate Cooper Flagg plays for the Dallas Mavericks. The two are the top candidates for NBA Rookie of the Year.
Back in Milwaukee, the Knueppel machine keeps running. Kager, a 6-8 sophomore, has D-I offers and led Wisconsin Lutheran to a second consecutive state title. Kinston is generating recruiting buzz. Kash and Kidman won the national Lutheran grade-school basketball tournament in Fort Wayne, Indiana. Chari is retiring from the daycare to focus full-time on five sons and their schedules. Kon Sr. still runs the men’s league. The six hoops are still on the property.
He was born in Milwaukee into a house with six basketball hoops. His father scored 2,064 points at Wisconsin Lutheran College. His mother scored 1,964 at UW-Green Bay. His uncle was drafted by the Bucks. His great-grandfather was NC State’s first All-American in 1932. His father’s brothers called themselves the Flying Knueppel Brothers. He didn’t score a point in his first ten basketball games because a Nintendo Wii had to teach him to love the sport first. He learned to play off the ball from a former Badger in his father’s men’s league. He played baritone in the high school band. He led Wisconsin Lutheran to a perfect season. He chose Duke because he wanted to practice against the best. He was Cooper Flagg’s roommate. He told the future number-one pick to get his head in the game. He won ACC Tournament MVP when Flagg went down. He was the fourth pick. He scored 32 against his hometown Bucks. And when he committed to Duke, he posted a photo: five brothers, each holding one of the program’s five national championship trophies. Five brothers. Five trophies. One family. The Knueppels don’t just play basketball. They are basketball.
