With training camp opening in September and the preseason right around the corner in early October, NBA teams are already filling out their rosters with a familiar kind of flyer: undrafted rookies on training camp deals.
Those contracts give clubs a longer look at young players who may still be chasing a two-way spot or a place in the G League. And this week brought another round of those opportunities for players from the 2026 class.
San Antonio, the regining Western Conference champions, added Miles Barnstable on an Exhibit 10 deal, according to Paul Garcia. Marc Stein also reported that Boopie Miller will land a similar contract with the Denver Nuggets, another Western Conference contender.
Elsewhere, the Thunder brought back Holifield after giving him a shot with their Summer League group. He joined Oklahoma City as an undrafted free agent out of Lamar, where he spent two seasons.
As a senior, the 6-foot-10 forward put up 11.7 points, 4.6 rebounds, 1.5 assists and 1.7 blocks per game while shooting 38.1% from the field and 30.2% from 3-point range on 5.5 attempts a night. Holifield didn’t see much floor time in Summer League, but he clearly did enough to earn another look from Oklahoma City.
The Thunder have built a reputation for uncovering and developing undrafted talent, and Branden Carlson is the latest example. Carlson went unselected in 2024, spent time as a two-way player with the Thunder, and recently signed a standard contract with Portland.
The Lakers also gave McCray a Summer League opportunity in 2026 after a long college run that spanned five years. He played four seasons, plus a redshirt year, at Jacksonville State before finishing at Florida State.
At Florida State, the 6-foot-4 guard averaged 16.3 points, 6.1 assists, 3.8 rebounds and 1.3 steals per game, while shooting 45.8% from the field and 35.5% from beyond the arc.
Schieffelin took the most unusual route of the bunch. After four years as a Clemson basketball forward, the 6-foot-8 veteran spent the 2025-26 season as a tight end for the Tigers’ football team. He then joined Miami’s Summer League squad in 2026 and turned in a few solid outings.
In his most recent season on the hardwood, Schieffelin averaged 12.4 points, 9.4 rebounds and 2.7 assists per game while shooting 49.5% from the field and 34.1% from deep.

Cason Wallace Suddenly Carries A Bigger Thunder Question Than Expected
Cason Wallace entered the summer with a familiar kind of Thunder pressure, the sort that comes with a young player suddenly looking like part of the next layer of the rotation. With Oklahoma City reshuffling its perimeter group, Wallace is in the mix to absorb a bigger role as the season nears, and he has handled the added attention the same way the team has handled most of its business: calmly, with the focus kept on what comes next rather than what has changed.
There is another layer to the conversation, though, and it is the kind that tends to follow promising players in Oklahoma City once they start looking indispensable. Wallace is eligible for an extension this summer, and the talks are ongoing even if both he and Mark Daigneault say it is not becoming a distraction. For now, the Thunder are trying to keep the conversation centered on development and performance, but the calendar gives the situation a little more urgency than the usual offseason backdrop.

Thunder Training Camp Just Put Real Pressure On One Roster Battle
With Media Day and training camp opening, the Thunder are moving into the kind of fall that tends to reveal more than it resolves. Oklahoma City is set to begin its 2026-27 preparations with a full camp roster, giving the staff a chance to look closely at the young players and invitees who will spend the next few weeks trying to carve out a place in the mix before the season opener against the Spurs.
There is still real business to sort through, even for a team that has spent recent seasons building with a clear plan. The final roster spot is one part of it, but the deeper question is how the Thunder fill the minutes and responsibilities left behind by offseason departures while also deciding which of the newer faces can actually stick once camp competition starts to harden.

Otega Oweh Suddenly Faces A Real Thunder Problem This Preseason
Sam Presti spent part of the preseason talking about the NBAs new 3-2-1 draft lottery format and why it could make the league more competitive while cutting down on tanking, but the same broader shift could create a more ordinary problem for Oklahoma Citys own young players. The Thunder have long leaned on big rotations to help develop talent, and that approach has usually given prospects room to grow while the games still matter.
This preseason, though, tighter margins could make those minutes harder to find for second-round pick Otega Oweh. If the Thunder are playing more competitive games and shrinking the floor for developmental reps, his path could get complicated quickly, especially with the team weighing how best to handle his roster status and long-term growth.
