The Thunder Traded Away Three Rotation Pieces. Now Cason Wallace Has a Much Bigger Job.
Oklahoma City spent the summer moving Lu Dort, Aaron Wiggins and Isaiah Joe. The defending 2025 champions still have Shai Gilgeous-Alexander and an elite core, but the next version of the Thunder may depend on Cason Wallace turning last season’s expanded role into a permanent one.
Thunder Brief
- Oklahoma City traded Lu Dort, Aaron Wiggins and Isaiah Joe during the 2026 offseason.
- Wallace started 58 of his 77 regular-season appearances in 2025–26 and averaged 9.3 points, 3.1 rebounds, 2.9 assists and 2.1 steals in those starts.
- The Thunder retained center Isaiah Hartenstein on a new deal through 2028–29 and added 2026 first-round picks Aday Mara and Bennett Stirtz.
- OKC opens the 2026–27 regular season Oct. 20 at San Antonio in a nationally televised rematch with the team that eliminated it in Game 7 of the Western Conference Finals.
Oklahoma City’s summer was not a teardown. It was a redistribution.
The easiest way to misunderstand the Thunder’s offseason is to count recognizable names going out and assume the roster simply got thinner. Lu Dort, Aaron Wiggins and Isaiah Joe all mattered. Dort supplied point-of-attack defense and physicality. Wiggins gave Mark Daigneault a flexible two-way wing. Joe was one of the league’s better volume three-point shooters.
But Oklahoma City has spent years building a roster that is supposed to survive exactly this kind of turnover. The question is not whether those players were useful. It is whether the next layer of the roster is ready to inherit their minutes without changing what made the Thunder dangerous.
No player sits closer to the center of that question than Cason Wallace.
Wallace already gave OKC a preview last season
Wallace’s 2025–26 season quietly changed his place in the hierarchy. With Jalen Williams missing significant time, Wallace started 58 of his 77 regular-season appearances. In those starts he averaged 9.3 points, 3.1 rebounds, 2.9 assists and 2.1 steals in 27.7 minutes.
The steals number jumps off the page, but the more important development was trust. Starting that many games on a 64-win team is not a developmental courtesy. It means Wallace was already being asked to defend important matchups, keep the ball moving and fit beside higher-usage creators without needing possessions designed for him.
Now Dort is gone. That changes the scale of the assignment.
Replacing Dort is not about finding another Dort
Oklahoma City sent Dort to Atlanta in a three-team trade in July. The Thunder also moved Wiggins to Atlanta and Joe to Detroit in separate offseason deals. Those moves opened minutes on the perimeter, but they also removed three very different skills from the rotation.
Wallace is the obvious candidate to absorb the largest share of the defensive responsibility. He has the hands, anticipation and willingness to pick up guards high on the floor. What he does not need to do is imitate Dort possession for possession.
The better version of this transition is collective. Wallace takes the hardest guard matchup more often. Alex Caruso continues to create chaos. Jalen Williams handles bigger wings when healthy. Shai Gilgeous-Alexander remains an opportunistic defender rather than carrying every difficult assignment. The Thunder’s defense has always been strongest when pressure comes from everywhere.
The offensive question matters just as much
Dort’s departure also creates shots. Joe’s departure creates even more. Oklahoma City cannot simply replace those possessions with extra Shai isolations and expect the offense to become better.
Wallace’s path to a full-time starting role therefore runs through his offensive decisiveness. He does not have to become a 20-point scorer. He does have to punish defenses that load up on Gilgeous-Alexander, Williams and Chet Holmgren.
That means taking open threes without hesitation, attacking tilted defenses when the first closeout arrives and making the next pass quickly enough that Oklahoma City’s advantage does not disappear.
Sam Presti did not stop adding options
The roster turnover did not leave Oklahoma City without alternatives. The Thunder retained Isaiah Hartenstein through the 2028–29 season. They also selected 7-foot Aday Mara with the No. 12 pick in the 2026 draft and acquired guard Bennett Stirtz at No. 16.
Mara arrives after helping Michigan win the 2026 NCAA championship while averaging 12.1 points, 6.8 rebounds and 2.6 blocks. Stirtz averaged 19.8 points and 4.4 assists at Iowa and led the Hawkeyes to their first Elite Eight.
Those rookies do not have to carry the Thunder immediately. Their presence matters because Oklahoma City can keep developing internally while asking Wallace, Ajay Mitchell, Jared McCain and other young guards to compete for the vacated perimeter work.
The opening-night matchup makes the transition impossible to hide
The Thunder open Oct. 20 in San Antonio against the Spurs—the same team that ended Oklahoma City’s 2026 postseason in Game 7 of the Western Conference Finals.
That game will be on NBC and Peacock at 9:30 p.m. ET. It is not just a marquee opener. It is a direct examination of the Thunder’s offseason choices.
San Antonio’s size and creation stressed Oklahoma City in the conference finals. If Wallace is going to inherit a larger defensive role, opening night offers about as demanding a laboratory as possible.
Why the Thunder can afford this kind of offseason
Oklahoma City is operating from a position most teams never reach: a championship core, an MVP-level centerpiece, young stars and enough accumulated draft capital to keep refreshing the roster.
Gilgeous-Alexander is coming off another extraordinary season. In March he passed Wilt Chamberlain for the longest streak of 20-point games in NBA history, reaching 127 consecutive games. The Thunder won 64 games and reached another Western Conference Finals before San Antonio ended the repeat bid.
That combination creates pressure, but it also creates freedom. Oklahoma City does not need every offseason move to produce a famous name. It needs the ecosystem around its stars to stay younger, flexible and financially manageable.
Three things to watch when camp opens
- Who starts next to Shai? Wallace has the clearest defensive case, but Oklahoma City has enough guard depth to experiment.
- Where do Joe’s three-point attempts go? Spacing is a team resource. Someone has to replace the volume he took to Detroit.
- How often does Wallace initiate? If the Thunder trust him with more secondary ball-handling, it will tell us his promotion is bigger than a defensive assignment.
The bottom line
The Thunder did not trade Dort, Wiggins and Joe because those players stopped helping. They made the moves because sustainable contenders eventually have to turn development into responsibility.
Cason Wallace is now standing at that handoff point.
He already proved he can start for a 64-win team. The next question is harder: can he become one of the players who defines the next version of Oklahoma City basketball?
We start finding out against San Antonio on Oct. 20.
