By absorbing the interior’s physical toll, the veteran big man preserves Chet Holmgren’s health and shields Oklahoma City’s stars from the grueling friction of an 82-game season.
The Oklahoma City Thunder did not guarantee Isaiah Hartenstein another $75 million simply because they needed a traditional center. They retained him because he can provide something even more valuable during the 2026-27 season: protection for the franchise's championship core. If Oklahoma City genuinely intends to pursue another deep playoff run, Hartenstein should become the player who absorbs the physical burden of the regular season.
Hartenstein appeared in only 47 games last season, but still averaged 9.2 points, 9.4 rebounds and 3.5 assists. Those numbers demonstrate how much he can provide without requiring Oklahoma City to build its offense around him. He screens, rebounds, passes and creates easier possessions for the players surrounding him. That reliability should allow Mark Daigneault to manage Chet Holmgren more carefully without weakening the Thunder's frontcourt every time Holmgren rests.
This is especially important after Oklahoma City watched injuries affect another postseason run. Jalen Williams was unavailable at the end of the Western Conference Finals, while Ajay Mitchell also missed critical time. The Thunder cannot eliminate injuries, but they can avoid creating unnecessary physical strain for their most important players. Allowing Hartenstein to battle traditional centers, control the glass and handle difficult interior assignments could preserve Holmgren for matchups that demand his versatility.
There will be nights when Hartenstein's role appears too large for a team with championship expectations. That should not matter. Oklahoma City does not need every regular-season lineup to resemble its eventual playoff rotation. The priority should be reaching April with Gilgeous-Alexander, Williams and Holmgren operating as close to full strength as possible. Hartenstein provides Daigneault with the freedom to prioritize that objective without sacrificing the interior presence necessary to win games.
His new contract should therefore be judged by more than postseason minutes or scoring averages. Hartenstein can help Oklahoma City survive the exhausting portion of an 82-game schedule while giving younger centers such as Aday Mara and Thomas Sorber time to develop properly.
He can also keep Holmgren from constantly absorbing punishment against the NBA's strongest big men. The Thunder's stars will ultimately determine whether another championship arrives, but Hartenstein could determine how healthy those stars are when that pursuit begins.
More importantly, his presence gives Daigneault an experienced alternative when matchups become overly physical. That flexibility could reduce unnecessary wear, stabilize the rotation and ensure Oklahoma City's most important frontcourt weapon is prepared for another demanding postseason run in April.
