Darryn Peterson Finally Figured Out What Wrecked His Freshman Season, and NBA Teams Are Listening

Kansas guard Darryn Peterson has an answer for the question that's haunted his freshman year: why did a potential No. 1 pick in the 2026 NBA Draft suddenly disappear from games without explanation? High-dose creatine use. That's it. That's the thing that sent him to the hospital, cost him 11 games, and made his season feel like a stop-start disaster nobody could quite understand.

The Hospital Visit That Changed Everything

Peterson didn't hold back when describing the moment during Kansas' preseason conditioning program when his body basically mutinied on him. "I thought I was going to die on the training table that day," he told ESPN, recalling the full-body cramping episode that landed him in the hospital needing IV fluids.

Here's what went down: Peterson had never used creatine before getting to college. Once he started supplementing, his baseline creatine levels were already elevated. Adding more to the mix pushed everything into dangerous territory. The cramping started early in the season and escalated fast, moving from his legs to his entire body. By the time trainers got him to the training room, he was begging them to call 911. "They were trying to get a vein to get me the IV, get me back hydrated," Peterson said. "But I was cramping so hard they couldn't get a vein."

Playing Through the Unknown

Kansas officials couldn't say much publicly because of medical privacy rules, but coach Bill Self later acknowledged the uncertainty surrounding Peterson's condition messed with both the kid's rhythm and the team's consistency. All season long, Peterson tried everything: hydration strategies, electrolyte supplements, IV treatments, dietary changes. He played through discomfort at times, but missed 11 games outright and had to exit others early when the cramping came back.

"Whenever I felt anything like that come on, my initial thought was that it might get to that again," Peterson told ESPN. "And I can't let that happen and be embarrassed and have that on TV and all that."

By late in the season, Peterson started logging more consistent minutes, including several 30-plus-minute performances. Once he stopped taking creatine, the issue began to subside. He's since resumed training in Los Angeles ahead of the NBA Draft combine with no further cramping episodes.

What This Means for Draft Day

Peterson remains firmly in the conversation for the No. 1 overall pick despite the uneven year. His draft stock hasn't collapsed. What matters now to NBA teams is whether they view this as a correctable supplement issue or a sign of an underlying injury concern. That distinction could be the difference between going first overall and falling down the board.
