The New York Knicks are grappling with the departure of center Isaiah Hartenstein to the Oklahoma City Thunder, who offered him a more lucrative three-year, $87 million deal. Hartenstein had become a key defensive player for the Knicks, who now face a shortage at the center position. The Knicks are exploring options including free agency, where Precious Achiuwa appears to be the most viable candidate, and trades, with interest in Utah Jazz's Walker Kessler. Meanwhile, the Thunder have significantly strengthened their roster with the addition of Hartenstein, enhancing their defensive capabilities. OKC's moves also include acquiring Alex Caruso and Nikola Topic, aiming to bolster their frontcourt depth following a playoff exit.
