The Oklahoma City Thunder’s Western Conference Semifinals exit last season against the Dallas Mavericks exposed a glaring weakness in their roster construction.

Dallas big men Dereck Lively II and Daniel Gafford dominated the paint, bullying the Thunder’s undersized frontcourt throughout the series.

Oklahoma City’s front office recognized this fatal flaw and made a decisive move during the offseason. They signed Isaiah Hartenstein to a three-year, $87 million deal, addressing their most pressing need with a proven playoff performer.

The investment has paid immediate dividends, with Hartenstein emerging as a cornerstone of the Thunder’s Western Conference Finals run.

Hartenstein posts career-high numbers in Thunder debut season

Hartenstein’s transition from New York to Oklahoma City has been seamless, with the veteran center posting career-best statistics across multiple categories.

He averaged 11.2 points, 10.7 rebounds, and 3.8 assists during the regular season, all personal highs.

His impact extends far beyond traditional box score metrics. Hartenstein’s ability to pass, rebound, and defend as a mobile big man has transformed the Thunder’s offensive and defensive schemes.

Last season with the Knicks, Hartenstein appeared in 75 games while transitioning from reserve to starter after Mitchell Robinson’s ankle injuries.

His playoff experience in New York’s Eastern Conference Semifinals run proved invaluable preparation for Oklahoma City’s championship aspirations.

Defensively, Hartenstein has anchored the Thunder’s interior presence throughout their playoff run. His rim protection has been elite, holding opponents to just 48.3% shooting within six feet of the basket.

His most impressive defensive showcase came during the semifinals against Denver, where he successfully neutralized three-time MVP Nikola Jokic in crucial moments.

In Game 4, Jokic managed just 3-of-10 shooting when Hartenstein served as the primary defender.

This defensive versatility has become crucial in the Western Conference Finals, where Hartenstein faces the challenge of containing players like Rudy Gobert and Julius Randle.

The Thunder’s decision to commit significant money to Hartenstein has validated their front office’s strategic vision.

His integration has addressed previous rebounding deficiencies while adding frontcourt depth that was noticeably absent during last season’s playoff disappointment.

With Hartenstein on the team, Oklahoma City can now go head-to-head with any Western Conference opponent, no problem. They’re no longer at a disadvantage when it comes to size.

And as the Thunder keep going for the championship, it looks like their investment in players who’ve done well in the playoffs is really paying off.
