The Oklahoma City Thunder have signed Isaiah Hartenstein to a three-year, $87 million deal, making it the largest free agent signing in the team's history. Hartenstein, who was previously with the New York Knicks, is expected to play a significant role in bolstering the Thunder's roster as they push for a title. Both Hartenstein and Thunder GM Sam Presti emphasized that there are no guarantees for starting roles or minutes, but the focus will be on creating a conducive environment for success. Hartenstein's versatility and elite defensive skills are anticipated to complement young stars like Shai Gilgeous-Alexander and Chet Holmgren. Hartenstein and his wife, Kourtney Kellar, expressed their gratitude to New York City as they look forward to their new chapter in Oklahoma City. The couple also announced they are expecting their first child.
