They were college teammates. They shared a locker room at Duke. They went first and fourth in the same NBA Draft. And then they spent the entire 2025-26 season locked in the most entertaining, most debated, most statistically extraordinary rookie race the league has seen since Luka Doncic and Trae Young in 2018-19.
Cooper Flagg went to the Dallas Mavericks. Kon Knueppel went to the Charlotte Hornets. And what followed was the kind of parallel breakout season that basketball history books will reference for the next twenty years.
This is the deepest comparison you will find anywhere. Let us get into it.
THE BACKGROUNDS
Cooper Flagg was born December 21, 2006, in Newport, Maine. He is 6 foot 9, 205 pounds, a forward who can genuinely do everything. He reclassified a year early to enroll at Duke as a 17 year old in 2024, immediately winning every major national player of the year award in his sole college season. He averaged 19.2 points, 7.5 rebounds, 4.2 assists, 1.4 steals and 1.4 blocks per game for the Blue Devils, leading Duke to the Final Four and becoming only the fourth freshman in NCAA history to win the Wooden Award, joining Kevin Durant, Anthony Davis and Zion Williamson.
He was the unanimous number one pick in the 2025 NBA Draft, selected by Dallas. The hype surrounding Flagg entering the NBA was the highest for any prospect since LeBron James. His floor was described by scouts as higher than almost any projected number one pick in history because of his defensive versatility. His ceiling was described as limitless.
Kon Knueppel was born August 3, 2005, in Milwaukee, Wisconsin. He is 6 foot 7, 217 pounds, a shooting guard and small forward who grew up in a basketball family where his mother, father, and uncle all played in college and his uncle Jeff Nordgaard briefly played in the NBA. Knueppel won Wisconsin Mr. Basketball in 2024 after leading Wisconsin Lutheran High School to a state championship. At Duke alongside Flagg, he averaged 14.4 points, 4.0 rebounds and 2.7 assists while shooting 47.9 percent from the field, 40.6 percent from three and an astonishing 91.4 percent from the free throw line, the second highest single season mark for a freshman in Duke history.
He won ACC Tournament MVP, averaging 21 points, 6.7 rebounds and 4.7 assists across three tournament games as he led Duke to the title. Most pre-draft projections had him landing in the late lottery range. The Hornets took him fourth overall. Many considered it a slight reach at the time.
Nobody considers it a reach anymore.
THE ROOKIE SEASONS: BY THE NUMBERS
WATCH THE FULL VIDEO HERE:
Cooper Flagg played 70 games, started every single one, and averaged 21.0 points, 6.7 rebounds, 4.5 assists, 1.2 steals and 0.9 blocks in 33.5 minutes per game. He shot 48 percent from the field. He posted a True Shooting percentage of 54.8. He became only the third rookie in the last 45 years to average at least 20 points, six rebounds and four assists, joining Michael Jordan and Luka Doncic. He led all rookies in 25-point games, 30-point games, 35-point games, and 40-point games. He scored 51 points in a game against Orlando. He became the youngest player in NBA history to score 50 points. He led the Mavericks in points, rebounds, assists and steals simultaneously, something only Michael Jordan had done as a rookie since the league began tracking steals in 1974.
Kon Knueppel played 81 games, started 80, and averaged 18.5 points, 5.3 rebounds, 3.4 assists and 0.7 steals in 31.5 minutes per game. He shot 47.5 percent from the field, 42.5 percent from three and 86.3 percent from the free throw line. He nearly achieved 50-40-90 efficiency, a mark that even established veterans rarely touch. He broke the NBA record for three pointers made by a rookie, surpassing Keegan Murray’s mark of 206 by finishing with well over 212 made threes. He became only the third rookie in NBA history to average 15 or more points and five or more rebounds while shooting above 40 percent from beyond the arc.
SCORING: EDGE FLAGG
Flagg was the more explosive scorer with the higher ceiling. His 51-point game against Orlando was a watershed moment for the entire rookie class. He also scored 49 and 45 in separate performances late in the season. When Flagg locked in offensively there was genuinely nothing a defense could do. He can score in the post, in the mid-range, at the rim, and from three, and he is still developing his three-point shot which shot up as a concern going into the draft.
Knueppel is the more efficient and consistent scorer. He almost never takes bad shots. His mechanics are so clean and so repeatable that shooting coaches around the league have studied them. He does not go for 51 but he also does not go for 8. He gives you 18 to 22 almost every single night with remarkable reliability.
Edge: Flagg for ceiling. Knueppel for consistency.
THREE-POINT SHOOTING: KNUEPPEL BY A MILE
This is not close. Knueppel broke the all-time rookie record for three pointers made in a season. He shot 42.5 percent from three while attempting nearly 8 per game, numbers that most accomplished veterans would envy. His release is quick, his range is deep, his footwork coming off screens is already at an elite level.
Flagg improved his three-point shooting dramatically from college but it remains the one area of his game where questions still linger. He is not a liability from three but he is not the weapon Knueppel is either.
Edge: Knueppel, and it is not close.
DEFENSE: FLAGG BY A SIGNIFICANT MARGIN
This is the most important separator between the two players in terms of their long-term ceilings. Flagg can guard one through five depending on the opponent. His length, his instincts, his positioning and his willingness to compete on that end every single night are all elite. He has already established himself as an anchor for Dallas’s defense. His defensive rating of 114.7 compares favorably to Knueppel’s 113 on the surface, but those numbers do not reflect the quality of opponents each player was assigned.
Knueppel is a solid, competent defender who plays with high IQ. He does not get burned badly in his defensive assignments and his positioning in team schemes is reliable. But he is not a stopper and he never will be. His average athleticism limits his defensive upside in ways that Flagg simply does not face.
Flagg has already been mentioned in All-Defensive conversations as a second-year candidate by multiple analysts. Knueppel will never generate that kind of conversation.
Edge: Flagg, decisively.
TEAM SUCCESS AND CONTEXT
This is the most complicated and honestly the most unfair part of the comparison. The Mavericks were a disaster. Anthony Davis went down with injury. Kyrie Irving was out. Flagg was thrust into being the primary option on a team that went 21-45 in games he played. His individual plus-minus was a dreadful minus 275 not because he played poorly but because the team around him was genuinely bad. He was doing everything alone.
Knueppel landed in a completely different situation. LaMelo Ball is a dynamic playmaker who creates extraordinary space for everyone around him. Brandon Miller and Miles Bridges provide additional shot creation. Charlotte went 32-13 from January 2nd onwards with the NBA’s best offensive rating in that stretch. Knueppel’s plus-minus was a remarkable plus 326. His on-court rating of plus 6.5 tells you what the Hornets looked like when he was playing.
The Hornets reached the play-in tournament. The Mavericks did not come close.
Does Knueppel’s situation make his numbers somewhat inflated? Partially. But it also does not diminish the fact that he seized the role perfectly, played with incredible maturity, and helped transform Charlotte’s culture in a genuine way. Most fourth overall picks do not arrive and immediately help their team reach the postseason.
THE VERDICT: WHO WON THE ROOKIE RACE?
Flagg won the award. He averaged more points, led a worse team as its only star, posted more historic individual performances, and demonstrated the kind of two-way versatility that nobody on that Dallas roster could even approximate.
But Knueppel made it the closest race in years. At various points during the season, betting odds had him as the favorite. NBA.com’s weekly rookie ladder had him at number one heading into the final weeks. He was more efficient, his team was better, and there is a real argument that in terms of immediate positive impact relative to situation, he was the better player.
LONG TERM CEILING: WHO BECOMES THE BETTER PRO?
This is the most interesting question and the one where opinions genuinely diverge.
Most analysts project Flagg as a future top-five player in the league. The comparison to Jayson Tatum is unavoidable and not unfair. He is a two-way forward who does not have a weakness, just areas to develop. He turned 19 during the season. He is getting better every single month.
Knueppel is projected as a future All-Star caliber player rather than a franchise cornerstone. The comparisons to Khris Middleton and Desmond Bane capture his ceiling well. He will be an elite complementary star who makes everyone around him better, shoots at a level that stretches defenses to their limits, and competes on defense hard enough to not be a liability.
The gap in ceiling exists. Flagg has the higher one. But Knueppel’s floor is extraordinarily high as well, and in a league that values shooting above almost everything else right now, his skill set will be relevant for the next fifteen years.
FINAL THOUGHT
What made this rookie race so special was not just the numbers. It was the story. Two college teammates, drafted three picks apart, immediately going to separate cities and competing against each other for the most prominent individual award of their first professional season.
They both delivered. They both made history. And the NBA is considerably more interesting for having both of them in it.
Flagg won the trophy. But this rivalry is just beginning.
