Thunder Rumors: Giannis, Mobley, Hartenstein, Draft

The Thunder were unable to defend the championship they won last year, and there’s an expectation around the league that their roster will look different in 2026/27, writes Marc Stein of The Stein Line (Substack link).

However, none of the rival executives Stein has spoken to “strongly believe” Oklahoma City will pursue Giannis Antetokounmpo in the wake of the Thunder being eliminated from the postseason. That more or less echoes previous reporting from Sam Amick of The Athletic.

President of basketball operations Sam Presti has frequently taken a long-term approach to team-building over the past several years, Stein notes, and the Thunder came close to winning the Western Conference finals despite missing Jalen Williams and Ajay Mitchell for most of the series.

The Thunder certainly have the assets to make a blockbuster trade if they want to, but a deal for the Bucks superstar “would genuinely shock” people around the league, according to Stein. That’s partly because Antetokounmpo’s presence could dramatically change the meticulously developed culture Presti has helped foster in Oklahoma City.

Here are a few more rumors related to the Thunder:

• Amick reported that there’s long been “chatter” about the Thunder’s interest in Evan Mobley, and league sources tell the Stein Line that OKC tried to acquire the third pick in the 2021 draft in order to select the former USC big man. However, the Cavaliers “rebuffed” those efforts, according to Stein, who points out that president of basketball operations Koby Altman tried to preemptively shut down potential inquiries on Mobley at his end-of-season press conference last week. Altman called the 2024/25 Defensive Player of the Year a “a huge part of what we do” and “consistently our best player throughout the playoffs,” per Stein.
• Joe Mussatto of The Oklahoman (subscriber link) recently suggested the Thunder are likely to decline their $28.5MM team option on Isaiah Hartenstein with an eye on re-signing their starting center to a long-term deal. Stein has heard similarly, writing that early indications point to Harteinstein remaining on the team in ’26/27, even if that option is declined.
• Multiple reports have indicated that the Thunder are expected to be aggressive with their two first-round picks (Nos. 12 and 17), perhaps with a goal of moving up to select Cameron Boozer. However, rival clubs have gotten the sense that Wizards, Jazz, Grizzlies and Bulls are determined to stay in the top four, according to Stein, who says a “more realistic trade-up target” for Oklahoma City could be Aday Mara.
