We all remember June 22, 2025 — the night OKC closed out the Pacers in Game 7 of the Finals. That confetti at Paycom Center wasn’t just for a win; it marked the Thunder’s first-ever NBA title since moving to Oklahoma City. Their 84th win of the season? Straight into the history books. But while most of us were sold on this epic run… Gilbert Arenas wasn’t. And something tells us Isaiah Hartenstein’s not letting him forget that anytime soon.

Isaiah Hartenstein, who averaged career-highs in minutes (27.9), points (11.2), rebounds (10.7), and assists (3.8) during OKC’s 68-win regular season, played all 23 playoff games on the way to his first NBA title — and made sure Gilbert Arenas felt it. “Before we keep going, aye, Gil, you said 0%?” Hartenstein teased. Arenas tried to play the Lakers fan card, but the big man didn’t let it slide: “I think that might have been one of your worst takes.” Because when you win it all, you’re allowed to pull out the receipts.

To his credit, Gilbert Arenas took it like a man (well, sort of). On Gil’s Arena, he offered up an apology—his version, anyway: “I’m very sorry for underestimating you and your hard work and journey. And um you proved me wrong and you won. And uh I did celebrate cuz I know how to jump ship at the right time. But congratulations.” Classic Gilbert—half sincere, half stand-up set. But hey, at least he said it. The Thunder proved the doubters wrong, and Isaiah Hartenstein? He got the last laugh, mic in hand.

Well, looks like Gilbert Arenas was really feeling the heat. After Isaiah Hartenstein called him out, Gil turned straight to his co-host and let him have it! “We going to have a conversation after… about your contract this summer,” Gil said, half-joking, half-salty. “Y’all had him come up here, didn’t screen him first—that’s crazy. And then you put the edit out? You were supposed to erase that!” Gil wasn’t done either—“We going back to negotiating on your contract. Guaranteed. Guaranteed.” Talk about deflecting like a pro!

Gilbert Arenas doubted OKC all along

The Oklahoma City Thunder were the only team in the West to hit the 60-win mark this season (finishing 68-14), locking up the best record in the league. So, naturally, you’d think they’d be favorites for a deep playoff run, right? Well, Gilbert Arenas didn’t think so. On his podcast Gil’s Arena, Arenas flat-out said, “To reach the Finals, I give them 0%,” throwing complete shade at OKC’s chances. His reason? He believed their regular-season success would backfire in the playoffs, especially with all their young stars heading into contract years. “With them, they’re all helping for the success… you gonna have to pay Shai the bank this summer. Chet can ask for money. Now you have Jalen Williams… he’s going to want the rookie max,” Arenas said.

Fast forward to June, and surprise — OKC did make the Finals, alongside the Indiana Pacers. Both teams proved the doubters wrong, fought hard every series, and earned their shot. But did that change Arenas’ opinion? Nope. Even after all that, Arenas still brushed it off, claiming this Finals would leave no lasting impact. His reasoning? No star-studded names, no big-market teams, and no dramatic storylines that fans usually cling to. “When it comes to small-market teams, we don’t really remember much about them… the only memorable thing was Hali’s game-winner (in) Game 1. Other than that, there was nothing in these finals that would make you say, ‘Oh My God, this was a great finals,’” he said.

Basically, Arenas thinks underdog stories don’t stick with fans the way big-city team wins do. Whether you agree with him or not, you have to admit—the man doesn’t hold back. He pointed out how people barely talk about the Raptors’ 2019 title or even the Bucks’ Giannis-led championship. And in his eyes, the same fate awaits this OKC vs. Indy Finals. It’s a harsh take, but classic Agent Zero—calling it like he sees it, whether fans like it or not.
