When you become an NBA champion, you get to enjoy a full summer of pulling out receipts from your drawer. Isaiah Hartenstein earned brownie points when he lived out every Oklahoma City Thunder fan’s dream. He called out Gilbert Arenas for mocking the squad and their title chances.

Before Hartenstein talked to Arenas in his talk show, the seven-footer brought up what he had previously said. Arenas said in April 2025 that the Thunder had zero chance of making the NBA Finals. That’s despite putting the final touches to one of the greatest regular season campaigns ever.

“Before we keep going, Hartenstein said. “Hey Gil, you said 0%?”

Arenas was left embarrassed and stuttering over his words in his explanation. He said the context was that he’s a Los Angeles Lakers fan, which made it understandable to be irrational about his team’s playoff odds. I mean, sure. LeBron James and Luka Doncic were bounced out of the first round.

“I think that might have been one of your worst takes,” Hartenstein said.

The Thunder heard all year that they were too inexperienced for their regular-season success to translate in the playoffs. Maybe it wasn’t as dominant, but OKC ended with an NBA championship. Hartenstein played a key role as a starter. He’s earned the victory lap.
