The rankings industry got Cooper Flagg exactly right and Kon Knueppel almost completely wrong, and the two-year gap between those verdicts tells you more about how we evaluate teenagers than any single mock draft ever will.
Flagg sat at No. 1 on the 2024 SC Next 100 for a reason that never required projection gymnastics. The Maine kid who reclassified after his sophomore year already played with zero ego and complete control of the game’s tempo. Montverde associate head coach Kevin Boyle Jr. put it plainly: “He had zero ego and never complained. He knew when to get his teammates involved and only cared about winning.” That trait traveled. At Duke he averaged 19.2 points, 7.5 rebounds and 4.5 assists, dragged the Blue Devils to a Final Four, became just the fourth freshman national player of the year, went first overall to Dallas, and walked away with Rookie of the Year. The tools were loud enough that every board kept him locked at the top. Correct call.
Knueppel is the miss that stings. He checked in at No. 19. Productive high-school scorer who led Wisconsin Lutheran to an undefeated state title and paced the EYBL in points, yet somehow still sat outside the top 15 on most composites. Two years later he sits fourth on the re-rank, right behind Dylan Harper and VJ Edgecombe, and the gap between those two numbers is the entire story of this class.
The Jump From 19 to 4 Was Not Luck
Knueppel did not suddenly discover a new skill set. He simply kept doing the thing evaluators undervalued: making the next right play at a high volume without needing the ball in isolation. At Duke he posted 14.4 points on 40.6 percent from three and 91.4 percent from the line, earned ACC Tournament MVP while Flagg sat with an ankle sprain, and still finished second-team All-ACC. Charlotte took him fourth overall. Then he set the NBA rookie record with 273 made threes, landed on the All-Rookie first team, and finished a razor-thin second in Rookie of the Year voting. The ESPN re-rank itself admits the obvious: “If not for Flagg, he would’ve won NBA Rookie of the Year.” Perfect fit, perfect usage, perfect context. Rankings that obsess over explosive first-step athletes and highlight-reel finishing still struggle to price pure shot-making and decision-making at that age.
Harper moving from fourth to second and Edgecombe holding third are clean. Ace Bailey sliding from second to fifth is the other soft miss, but nothing approaches the Knueppel leap. Jeremiah Fears jumping from the forties into the lottery conversation is another data point that the same boards were too slow to reward production and late physical growth.
Roommates, Rivalry, and What Rankings Still Miss
The Flagg-Knueppel connection makes the original gap even sharper. They shared a dorm and a backcourt. When the Rookie of the Year race tightened, Flagg was tracking the box scores every night. “I think also I was watching Kon just because that’s one of my brothers,” he said. “We had such a good connection, and we’re gonna be there for each other for the rest of our lives. I was watching him as a fan, as well, but there was obviously that competition at the same time.” Jon Scheyer called Knueppel “so solid” and full of winning plays. The kid himself shrugged off the ACC Tournament surge with “I didn’t really feel like I tried to turn it up a notch.” That temperament plus elite shooting is exactly the profile that high-school rankings still underweight until the numbers force a correction.
Evaluating high-school talent remains an inexact science. Injuries, role changes, and simple development curves will always scramble boards. Flagg was the rare case where the ceiling was already the floor. Knueppel was the more common case: a high-floor shooter whose upside only became obvious once the scheme and the spacing finally matched the skill. The 2024 class now has its first two years of receipts. The top of the re-rank looks a lot cleaner than the original list, and the biggest correction sits at No. 4 with a rookie-record 273 threes next to his name.
