For most of the 2025–26 NBA season, the Rookie of the Year award felt like a foregone conclusion. Cooper Flagg was the story, the highlight, the record-breaker. Nobody was seriously challenging him until the numbers started telling a very different story.
As the season wound down, advanced metrics began painting a complicated picture of Flagg’s actual impact on winning basketball. His net rating sat at -5.2, meaning the Mavericks were significantly worse when he was on the floor than when he was off it. His offensive rating of 109.5 was respectable but far from dominant from a team impact standpoint.
For analytically-inclined voters — a growing and increasingly influential bloc — those numbers matter enormously.
The Winning Impact Question
Traditional Rookie of the Year voting has always leaned heavily on raw statistics. Points, rebounds, assists. The eye test. The highlights. By those measures, Flagg wins the award without much debate.
But modern NBA evaluation has shifted. Voters who prioritize net rating, on-off splits, and actual team performance are now asking a question that feels uncomfortable for Flagg supporters: did Dallas actually get better when Cooper Flagg was on the court?
The -5.2 net rating suggests the answer may be no — or at least, not as much as the highlights implied.
Knueppel’s Case Grows Stronger
Enter Kon Knueppel. While Flagg was dazzling with individual performances, Knueppel was quietly contributing to a Charlotte Hornets team that turned its entire season around. The Hornets went from an 11-22 disaster to a play-in berth, and Knueppel’s historic shooting was a central reason why.
The debate is real now. And with Flagg sidelined by injury heading into the postseason, Knueppel has every opportunity to make his case even louder.
