'It was great': Isaiah Hartenstein reflects on decision to stay in OKC

In the 2026 NBA playoffs, Isaiah Hartenstein shifted from a luxury to an essential player for the Oklahoma City Thunder. The team successfully managed his expensive salary to keep him beyond two seasons. An extension offering three years and $75 million was a top priority during the offseason. Before that, Hartenstein was a journeyman.

However, he has enjoyed his best years with the Thunder, both individually and as a team. He has been a double-double machine and a key player in their starting lineup. Since joining the Thunder, they have won an NBA championship and almost another. At the 2026-27 Thunder Media Day, Hartenstein shared his thoughts about staying in OKC.

Despite taking a slight pay cut, he chose long-term security and a chance to win another championship over a quick payday. Hartenstein signed a $28.5 million team option for the 2026-27 season. Instead, both parties agreed to a three-year deal, with the final year being a mutual option in 2028-29. Even if he leaves early due to financial pressures, the Thunder could trade him for assets.

Despite cost-cutting measures, the Thunder remain a co-title favorite, along with the San Antonio Spurs. Hartenstein was crucial in their seven-game playoff series, helping defend Victor Wembanyama and providing size against loaded West frontcourts. The Thunder's commitment to Hartenstein is evident, as he initially joined the team in 2024 as a two-year rental.

However, his outperforming expectations and the question marks surrounding younger players like Thomas Sorber and Aday Mara made him a must-keep by the end of the Thunder's 2026 playoff run.
