Here’s a bold statement: In the high-stakes world of college basketball, where every point and highlight reel matters, Duke’s head coach Jon Scheyer is flipping the script with a mantra that’s as unconventional as it is powerful—the ‘98 percent’ rule. But here’s where it gets controversial: while most coaches preach giving 100 percent, Scheyer argues that the real game-changer lies in the 98 percent of the time players don’t have the ball. Intrigued? Let’s dive in.
In Durham, anyone stepping into Duke’s basketball program under Scheyer’s leadership is quickly immersed in this philosophy. It’s not about the flashy plays or the moments that make ESPN’s top 10—though those are important. Instead, it’s about the consistency in the unglamorous details: rebounding, defensive positioning, and the next-play mentality. As Scheyer explained at the ACC Tipoff, ‘The best teams I’ve been a part of, as both a player and a coach, are the ones that master the 98 percent.’
And this is the part most people miss: The ball is in a player’s hands only 2 percent of the time—unless you’re a point guard. Sure, a 30-point game can steal the spotlight, but championships are often won or lost in the small, relentless actions that make up the other 98 percent. Think diving for a loose ball, getting a crucial deflection, or being in the right defensive position to support a teammate. It’s the details that separate good teams from great ones.
Last season, the Blue Devils were stacked with talent, led by freshman phenom Cooper Flagg. But what set them apart wasn’t just their skill—it was their buy-in to Scheyer’s 98 percent mantra. This philosophy demands a mindset shift, especially for players coming out of high school, where their success is often measured by how much they handle the ball. ‘High usage is a negative thing now,’ Scheyer notes. ‘The NBA is looking for players who can thrive without the ball.’
This year’s Duke squad, ranked No. 6 in the AP preseason poll, is a fascinating mix of seasoned veterans like junior Caleb Foster and senior Maliq Brown, alongside five-star recruits such as the Boozer twins (Cameron and Cayden), Sebastian Wilkins, Nik Khamenia, and Italian freshman Dame Sarr. For the newcomers, the message is clear: ‘Don’t let the 98 percent slip,’ Foster warns. In college basketball, the margin for error is razor-thin, especially for teams with national championship aspirations.
Take Isaiah ‘Slim’ Evans, for example. The 6-foot-6 sophomore is a sharpshooter, hitting 41.6% of his 3-pointers last season. But Scheyer sees even greater potential. ‘His defense, off-ball activity, and rebounding are where he needs to take the next step,’ Scheyer says. It’s about expanding his game beyond scoring to make a consistent impact in the areas that truly win games.
Here’s a thought-provoking question: In a sport where individual stardom often overshadows team effort, is Scheyer’s 98 percent rule the key to sustainable success? Or does it risk undervaluing the players who can single-handedly change a game? Let’s discuss in the comments.
As the Blue Devils prepare for their 2025-26 season, with exhibition games against Central Florida and Tennessee before their opener against Texas, the goal is clear: return to the Final Four. Last year’s semifinal loss to Houston still stings, but it’s also fuel for this season. ‘The holy grail of college basketball is the Final Four,’ Scheyer says. ‘There’s glory or heartbreak—no in-between.’
With a roster brimming with talent and a philosophy that prioritizes the unseen efforts, Duke is poised to make another run. But will the 98 percent rule be enough to bring home the championship? Only time will tell. What’s your take? Does Scheyer’s approach resonate with you, or do you think it’s missing something? Share your thoughts below!
