Jon Scheyer Has Two Duke Decisions That Could Define This Season

As the Blue Devils gear up for their preseason, Coach Jon Scheyer navigates fierce competition to finalize Duke's powerful lineup with two key positions up for grabs.

Duke’s preseason has barely begun, but Jon Scheyer already has two lineup calls that could shape the Blue Devils’ opening stretch.

Practice started Tuesday for a team that looks loaded on paper, and the clock is moving fast: Countdown to Craziness is 10 days away, and Belmont is waiting just over two weeks from now in the preseason opener. Three starters already look set, which leaves Scheyer sorting through two key spots and four legitimate options.

The safest projection is in the backcourt. Wisconsin transfer John Blackwell is expected to start and looks like Duke’s best bet to lead the team in scoring. He’ll be flanked by Dame Sarr and Patrick Ngongba II, two major retention wins for Scheyer after both players could have tested the NBA Draft waters and landed in the late first/early second-round conversation.

That leaves point guard and power forward as the real battlegrounds.

At point guard, senior Caleb Foster has the edge because of his experience, and that matters. But sophomore Cayden Boozer is going to push hard for the job.

Boozer brings more as a facilitator and finished last season strong for Duke while Foster was dealing with injury and unavailable. Foster is the better shooter, and that still counts for plenty, but Boozer’s ability to steer the offense and create for teammates could be a big piece of what Duke wants on that end.

Even if Foster gets the nod, both guards should have meaningful roles.

The addition of five-star freshman Deron Rippey Jr. only deepens that backcourt. Duke has the look of one of the nation’s best groups there.

The bigger intrigue may be at power forward, where Duke is choosing between two highly touted freshmen. For a while, Cameron Williams looked like the clear favorite. Then Joaquim Boumtje Boumtje arrived late and had a huge summer, and that changed the picture.

Boumtje Boumtje is already being viewed as the favorite to go No. 1 overall in the 2028 NBA Draft, and he’ll play his freshman season at 17 years old. There will be an adjustment period as he gets used to college basketball, but his ceiling is the highest on the roster, and that makes him awfully hard to keep off the floor.

Williams and Boumtje Boumtje both bring versatility, and that gives Duke a chance to go big. One option would be sliding Williams to the three and pairing Boumtje Boumtje with Ngongba in the frontcourt. That could be the look best suited to handle Florida’s massive front line.

For now, though, the job is still open. Williams and Boumtje Boumtje are both going to play, but the starting spot is there to be won as Duke’s first practices unfold.

Duke Has Something To Prove In This Trap-Game Test

William & Mary flashed its upside right away this fall, and Duke has spent the week preparing for a team that knows how to hang around if it gets a foothold. The Tribes season opened with a wild comeback at Villanova, a finish that showed the kind of late-game burst that can make an underdog dangerous, even if the rest of the month has been uneven since then.

Since that opener, William & Mary has managed only one win in four games, including a lopsided loss to Fordham, but Duke linebacker Nick Morris, Jr. said the Blue Devils are taking the Tribe seriously because of that competitive nature. The bigger picture for Duke is simple enough: it is expected to win comfortably, yet it also has something to prove in a spot where a sluggish start could turn a routine Saturday into the kind of trap-game test teams remember.

Duke's Fast Start Faces An Early ACC Test Against In-State Rivals

Duke volleyball heads into ACC play with some early momentum, carrying an 8-2 start into a weekend that will say plenty about where the Blue Devils stand. The lineup has already produced a few encouraging signs, from Natalie Moravecs breakout scoring to Nikki Quinns steady work running the offense, and now the challenge gets more familiar and more relevant with in-state conference opponents waiting on the schedule.

Wake Forest and NC State each bring their own recent results and players to watch, which makes this first league stretch feel like more than just a pair of matches. For Duke, it is the kind of opening test that can validate a hot start quickly, and the answers will start arriving on the road before the Blue Devils settle back in and see how their early form holds up against ACC pressure.

Dukes Frontcourt Depth Suddenly Has An Early Concern

Dukes frontcourt depth has taken on a little early-season uncertainty as Drew Scharnowski works through a knee issue during preseason camp. The Belmont transfer is projected to back up center this season, so his health matters not just for the rotation but for how much flexibility Jon Scheyer has behind the starters.

Scheyer and Scharnowski have both struck an optimistic tone about the recovery, with the injury being handled carefully and the aim still to have him back before the season begins. For now, there is no firm timeline, which leaves the Blue Devils watching a spot they expected to stabilize rather than stress this early. [Read more 🡒]
