Road to Duke
John Blackwell grew up in Highland Park, Michigan, the son of a Big Ten guard. His father, Glynn Blackwell, played four seasons at Illinois from 1984 to 1988 — 106 games, 57 starts, 12.1 points per game as a senior. The basketball lineage was direct, but the path was not. John attended Brother Rice High School in Bloomfield Hills, where he was ranked the 26th-best combo guard in the nation by 247Sports and the third-best prospect in Michigan as a junior — averaging 13 points, 5 rebounds, and 4 assists per game while shooting 49% from three, the highest 3-point percentage of any high school player in the state that season.
Wisconsin came calling. He chose the Badgers over offers from VCU and others, signing with Greg Gard's program as a 6-foot-4 combo guard with a quiet game and a steady jumper. He arrived in Madison in 2023 as a relatively low-profile recruit by Big Ten standards.
By December of his freshman year, he was the talk of the conference. Blackwell was named Big Ten Freshman of the Week on November 27, 2023. Then again on December 11. Then a third time on January 22, 2024. He became the first Wisconsin freshman to win the award three times since Ethan Happ in 2015–16. He averaged 8.0 points per game on 45.1% shooting from the field and 45% from three, made the Big Ten All-Freshman Team, and earned a fourth Freshman of the Week — the first Badger to do that since Nigel Hayes a decade earlier.
The sophomore year was a leap. After Wisconsin lost Chucky Hepburn and AJ Storr to the portal, Blackwell stepped into the starting lineup and never left it. On January 3, 2025, he scored 32 points in a record-setting 116-85 demolition of Iowa. He averaged 15.8 points per game, the second-highest scorer on the team behind John Tonje, and made the Big Ten All-Tournament Team after Wisconsin reached the conference title game. All-Big Ten Honorable Mention. The trajectory was clear.
Then came the junior breakout. As the lead option on a 24-11 Wisconsin team that earned a No. 5 NCAA Tournament seed, Blackwell averaged 19.1 points, 5.1 rebounds, and 2.3 assists per game. He shot 43% from the field, 38.9% from three on more than seven attempts a game, and 85.9% from the line. He scored 30+ five different times. He hit 31 points on 9-of-17 shooting in a 91-88 overtime win over Illinois. He went for 34 with 10 rebounds in a 85-82 home win over Washington in March. In the NCAA Tournament first-round loss to High Point, he had 22 points and 10 rebounds. He earned third-team All-Big Ten honors and finished his career 11th on Wisconsin's all-time scoring list with 1,505 points across 105 career games and 72 starts.
The portal opened. Blackwell entered. UCLA visited. Illinois pursued. Louisville made a hard push. He visited Duke on April 21 — the day before the portal officially closed — and committed before the day was over. The crystal balls had pointed to Durham; they were right.
"I'm 6-foot-4, so I'm naturally a point guard," Blackwell said in his commitment statement. "And that's just things I didn't do at Wisconsin. There's no knock to them. It's just I want to elevate my game to go to the next level. So I think that's what sold me on them. And then just the guys around me, [they] competed for a national championship with those guys. And I'm surrounded by pros throughout practice. And we got so many good guys coming in and so many good guys returning. Yeah, like I said, it just felt like the best spot for me."
When asked about his on-court ambition for the year ahead, he was specific: "Yeah, obviously just showing my playmaking skills, be able to make the right reads through pick and rolls, through different actions, NBA pro actions. That's one area I want to show."
He arrives in Durham with one year of eligibility, a 6-foot-4 frame, the highest career-high 3-point percentage in his Michigan high school class, the No. 3 ranking in the entire transfer portal per On3, and the chance to be the lead scoring guard on a Final Four contender. The portal era at Duke, which began with Maliq Brown's transformation in one year from Syracuse to ACC Defensive Player of the Year, is now built around the same one-year veteran formula. Blackwell is the second-most coveted addition Scheyer has ever made through the portal. The first was Cooper Flagg's high school teammate joining the Brotherhood as a transfer. This one is different — a senior guard with three years of Big Ten battle scars, a chance to play with NBA-bound teammates, and one season to leave a mark.
At Duke
Blackwell committed to Duke on April 21 with one foot still in the NBA Draft. He had declared after his junior season, and the process did not flatter him. Jim Sumner, sizing up the new roster in May, wrote that "he didn't test or measure well in the combines and his scrimmages left something to be desired," and predicted he would come back. He did. On3 reported on May 22 that he was withdrawing and enrolling at Duke, which made him the rare player Scheyer has landed in the portal: a veteran scorer with 1,505 college points already on the board.
At media day on September 24, Scheyer framed the signing as a replacement for everything that had walked out the door in April. "We're replacing a lot of scoring and firepower with a proven scorer who's tough and competitive," he said. "And that's going to really help us throughout the whole year." Blackwell, asked about a non-conference schedule that runs through Michigan State, Illinois, Florida, UConn in Las Vegas and Texas Tech at Madison Square Garden, sounded like a player who had changed schools for exactly this. "As a player, these are games you get excited for," he said. "This is the biggest of the biggest stage. I'm just excited. I'm just excited to be in this position."
He traded Wisconsin's No. 25 for Duke's No. 13. At Countdown to Craziness on October 3 he led the Blue team with 10 points, including a three and a three-point play that put Blue ahead 18-14 before White rallied to win 29-24.
Where Is He Now
The fall of 2026 finds Blackwell where he said he wanted to be when he picked Duke: holding the ball on a team built to win in April. Analysts project him as the Blue Devils' leading scorer and the senior who sets the tone for nine newcomers. He has one season to do it. The kid from Brother Rice who left Wisconsin to chase a champion gets his first look at Cameron's crowds this month, with an exhibition against Tennessee and another at Kansas before the opener against Army on November 2.
