Former San Antonio Spurs assistant Sean Sweeney has pointed the finger squarely at his old team, rather than the New York Knicks, for the Spurs' defeat in the 2026 NBA Finals. Speaking on The Ryen Russillo Show, Sweeney - who has since moved on to become head coach of the Orlando Magic - offered a candid, if measured, post-mortem on a series San Antonio led at some point in every single game, yet ultimately lost.
The Spurs arrived at the Finals carrying real physical wear, having needed seven gruelling games to dispatch the Oklahoma City Thunder in the Western Conference Finals. It was the kind of battle that leaves marks - not just on legs, but on rhythm and confidence - and in a sporting summer packed with high-stakes drama, from the cup 2026 to the hardwood showpiece in New York, the margins between glory and heartbreak proved razor thin once again. "I think there's a little attrition having to go through the previous series," Sweeney said. "Two, bad luck. They told me if the games were like 46 minutes or whatever, we would've won 4-1."
That detail is as striking as it is painful for Spurs supporters. San Antonio built double-digit leads in all five Finals games, yet managed to close out only one of them. The Knicks clawed back repeatedly in the fourth quarter, turning what should have been a comfortable San Antonio championship run into a nerve-shredding collapse across multiple contests.
Mistakes, Not Youth, Were the Problem - But Youth Was Still a Factor
Sweeney was careful not to let San Antonio's inexperience serve as a convenient excuse, but he didn't dismiss it entirely either. "I think we just made more mistakes than we had made in the previous series," he said. "You can maybe say something to that, but you don't do what you did, and then all of a sudden become young." The implication is clear: the Spurs had already proven they could execute under pressure throughout a deep playoff run, so the late-game breakdowns in the Finals represented something of an aberration, not an identity.
He also raised a dimension of the Finals experience that rarely gets discussed openly - the media obligations. "The one thing I think that's a little different in the finals than the other rounds is when you have to do media in the finals, you have to answer questions even when you've played poorly or struggled," Sweeney said. "And you don't have to do that in previous rounds." For a young roster reaching the championship stage for the first time, the relentless scrutiny and mandatory press access after difficult performances can compound the mental load in ways that are difficult to quantify but very real.
Brunson Delivers the Knockout Blow
Whatever the internal factors at play, Jalen Brunson made sure the Knicks didn't need to rely solely on Spurs generosity. The point guard closed out Game Five with a franchise-record 43-point performance, sealing New York's first NBA title in 53 years in the process. Sweeney, who coached Brunson during his time in Dallas, allowed himself a half-smile about the achievement. "Happy for him - kind of," he said, a line that landed with the quiet wit of someone who knows exactly what those points cost him.
Brunson's explosion in the deciding game added a legitimate championship narrative to what might otherwise have been remembered purely as a Spurs implosion. The Knicks won this title, and Brunson earned it - but Sweeney's honest reflection makes clear that San Antonio will be haunted for some time by the knowledge that the championship was there for the taking.
What Comes Next for a Spurs Side That Came So Close
The manner of the defeat - blown leads, not fundamental deficiencies - will sting, but it also offers San Antonio a realistic basis for optimism heading into next season. A team that dominates stretches of every Finals game is not far away. The question is whether the coaching staff that replaces Sweeney's institutional knowledge can address the late-game execution issues before the window narrows. For Sweeney himself, the task is now rebuilding Orlando into a contender; for the Spurs, it is figuring out how not to let a Finals lead slip again.
