There is no shortage of reasons to be excited about Duke basketball entering the 2026-27 season. Jon Scheyer has assembled a roster with size, versatility, an experienced core, and plenty of young talent. The Blue Devils have the pieces to compete at the highest level, and it is easy to see why expectations are high. But there is a difference between seeing what a team could become and knowing what it will be. Much of the conversation around Duke has understandably focused on best-case scenarios, projecting what this roster might look like if its players reach their potential and everything falls into place. I tend to take a more cautious approach. That does not mean I am down on this team. It means I think there are several legitimate questions that will have a significant impact on how far Duke can go, and I venture to say the coaches probably have those same concerns in the back of their collective minds. None of the concerns I have are necessarily dealbreakers on their own. The question is how they might compound if the answers do not come quickly enough. Here are five things I will be watching as the season unfolds.
Can Patrick Ngongba Stay Healthy and Out of Foul Trouble?
Duke’s frontcourt has plenty of intriguing pieces, but Patrick Ngongba remains one of the most important players on the roster. His size, interior finishing, rebounding, and ability to protect the rim give the Blue Devils a valuable presence in the middle. When he is on the floor and playing confidently, he gives Duke a foundation around which the rest of the defense and offense can operate.
The concern is whether he can stay on the court consistently. Ngongba has dealt with injuries during his Duke career, including interruptions during both of his first two seasons. Staying healthy is the first requirement, but avoiding foul trouble is almost as important. Duke needs him to be a dependable presence, not someone Scheyer has to carefully manage because of how quickly he can pick up two fouls in the first half. This reared its ugly head during Duke’s first exhibition game against Belmont, with Ngongba picking up 3 fouls in the first half in just 9 minutes—to me this is concerning—even with having Drew Scharnowski and Cameron Williams as backups. They are not Pat Ngongba and don’t bring the abilities that Scheyer is banking on to help fuel this season. The words “offensive hub” have been used by Duke coaches to describe what they want and expect out of Big Pat but in order for those words to have any meaning, he has to be on the floor.
This also matters on the defensive end. If he has to sit, Duke may have to rely on younger frontcourt players who are still adjusting to college basketball, potentially changing how aggressively the team can defend the paint. Against teams with experienced, physical big men, that could become a problem. Ngongba does not necessarily have to play 35 minutes every night, but Duke needs to know it can count on him when the game is on the line.
How Quickly Can Joaquim Boumtje-Boumtje Adjust to College Physicality?
Joaquim Boumtje-Boumtje is one of the most intriguing players on Duke’s roster, and the excitement surrounding his potential is understandable. His skill set offers possibilities that go beyond what you traditionally expect from a young big man. There is a reason to believe he can become an important part of what Scheyer wants to do offensively this season and next. Potential, however, does not eliminate the adjustment that comes with playing college basketball. Boumtje-Boumtje is entering a game where he will regularly face players who are physically mature, have spent several years in college, and know how to use their strength to their advantage. Even talented freshmen can find that adjustment difficult, particularly around the basket, where every possession can become a battle for position. People often tout that he is just 17, but that realization has to also come as a caveat; he’s only 17.
The challenge will be whether he can hold his ground defensively, rebound through contact, and finish when opposing big men make him work for every inch. If he can do those things early, Duke gains another legitimate frontcourt option and can use its size in a variety of ways. If the adjustment takes longer, Scheyer may have to be more selective about his minutes and matchups than some of the preseason projections suggest. That would not make Boumtje-Boumtje a disappointment. It would simply be a reminder that development rarely follows a perfectly straight line. Duke can benefit from his talent this season while recognizing that the physical side of the college game may take time to master.
Can Duke Create Enough Space for John Blackwell?
John Blackwell gives Duke something they need; a proven scoring guard who can create offense and put pressure on a defense. His addition makes the backcourt more dangerous, but it also raises a question about how the pieces will fit together. Having several talented guards is one thing. Building an offense that consistently puts them in the best position to succeed is another.
Blackwell needs room to operate. He is at his best when he can attack advantages, get downhill, and use his scoring ability without having to navigate a crowded floor. Duke has other guards who need the ball, too, and the challenge will be finding the right balance between individual creation and collective offense. If the spacing is poor or multiple players gravitate toward the same areas, Duke could have stretches when its talent is obvious but the offense feels more difficult than it should. While I trust Jon Scheyer, a man who has shown year in and year out he’s always going to put a top offense together. It’s an area that could be a work in progress this season.
And it’s not necessarily a question of whether Blackwell can score—he’s proven that over multiple seasons. It is about how Scheyer builds lineups around him and how the other guards respond when they are asked to play without the ball. Can Duke maintain enough shooting and spacing to open driving lanes? Can its guards move, cut, and make quick decisions rather than taking turns initiating offense? Can Blackwell make an impact even when he is not the primary ball handler?
If those answers are yes, Duke could have a backcourt that overwhelms opponents in multiple ways. If not, there is a risk that the Blue Devils have more individual talent than offensive cohesion. The difference between those outcomes could be significant in games against elite defenses.
Can Dame Sarr Turn Aggression and His New Frame Into Consistent Production?
One of the more encouraging things to watch against Belmont was Dame Sarr’s willingness to be aggressive offensively. His defensive ability has long been an important part of his value, but Duke needs him to be more than a player who makes life difficult for opposing guards and wings. The more confidently he attacks, the more dimensions he can add to this team; it raises the floor for this team and gives them a many-headed monster offensively.
The next step is making that aggression sustainable. Sarr needs to look for opportunities to attack without forcing the issue and take advantage of openings when defenses close out and become a player opponents must account for on both ends of the floor. A few encouraging possessions in an exhibition are a positive sign, but the real test will be carrying that approach into regular-season games, when opponents have more film and will actively try to take away his strengths. Counter the counters, as some coaches say: what happens when those driving lanes are gone? When defenses adjust? One positive thing I saw was his ability to dish the rock when he drives; if this becomes a part of his floor game going forward and he can continue to grow it without overpenetrating or getting called for charges, watch out. It will open up more shooting opportunities for him as well as others. Defenses have to respect his drives, and teammates will benefit from the gravity he creates.
Free-throw shooting is another part of that equation. Getting to the line is valuable only if those opportunities reliably turn into points. Improving his conversion rate would make Sarr’s ability to attack the basket more productive and help Duke capitalize when games become physical or slow down late. Missed free throws can be especially costly in close games, where a team may have only a handful of opportunities to create separation.
Sarr does not need to become a high-volume scorer for Duke to benefit from his development. He needs to make defenses respect his offense, finish the opportunities he creates and continue bringing his defensive intensity. If he can do that, he becomes a much more complete player and gives Scheyer another reliable option when the offense needs a spark.
Can Duke’s Guards Complement One Another on the Floor?
On paper, Duke’s guard group is one of the most appealing parts of the roster. There is scoring, playmaking, experience, athleticism, and the potential for different combinations depending on the matchup. The depth should give Scheyer options, but depth alone does not guarantee that the pieces will work together. Scheyer mentioned this in an earlier press conference, something to the effect of depth only being as good as the sacrifice that players are willing to make.
The question is how the guards complement one another when they share the floor. Who initiates the offense? Who is most effective playing off the ball? Which combinations provide the best balance of shooting, defense, and playmaking? And how will players respond when they are asked to sacrifice touches or accept a different role than they might prefer? Those are not criticisms of any particular player. They are the practical challenges that come with building a backcourt featuring multiple players capable of handling the ball and creating their own offense. The best combination on paper is not always the best combination in a real game, and the lineup that works against one opponent may not be the right answer against another.
Scheyer has the luxury of options and differing skill sets and experience levels in that guard rotation, and the encouraging part is that Duke has enough talent to experiment. Scheyer can mix and match based on the opponent, and the competition for roles should give the team options as the season progresses. But the Blue Devils will need more than individual ability. They will need clear roles, good decisions, and a willingness to make the extra pass when a teammate has a better opportunity. If the guards develop that chemistry, Duke could become difficult to prepare for. If the pieces take time to fit together, the team may experience some uneven offensive stretches while everyone finds their place.
The Difference Between Potential and Winning
Generally I fall somewhere between a realist and an optimist, and none of these concerns changes the fact that Duke has the talent to put together an outstanding season. In fact, several of these questions are tied directly to what makes the roster so intriguing. Ngongba can anchor the frontcourt, Boumtje-Boumtje can give Duke another dimension inside, Blackwell can provide a scoring punch, Sarr can expand his offensive game, and the guards can give Scheyer the flexibility to attack different matchups. It’s the right time to ask these questions as roles start to be won, defined, and cemented this preseason. Every team enters the season with a vision of what it can become. The teams that meet their expectations are the ones that turn that vision into something dependable, particularly when the competition gets tougher and the margin for error shrinks.
For Duke, the biggest questions may not be about whether it has enough talent. They may be about availability, physical readiness, spacing, offensive consistency, and chemistry. Those things are less exciting to project than a player’s ceiling, but they often matter just as much when a season reaches its most important moments. I am not predicting that these concerns will derail Duke, and I do not think every question needs to be answered immediately. There is room for growth, and a roster with this much versatility should have time to find its best combinations. But I will be watching how these issues develop because they could tell us more about Duke’s ultimate ceiling than another preseason projection ever could. The potential is obvious. Now Duke has to show that the pieces can come together when winning matters most.
