The San Antonio Spurs have punched their ticket to the Western Conference Finals for the first time since 2017, and they're bringing a bold confidence with them. After dismantling the Minnesota Timberwolves in a decisive Game 6 victory, the Spurs now face their toughest challenge yet: a showdown with the defending champion Oklahoma City Thunder.

The Thunder enter the series as the only undefeated team remaining in the playoffs, making them the clear favorites. But don't tell that to sophomore guard Stephon Castle. While all eyes naturally fall on superstar Victor Wembanyama — and rightfully so — Castle has emerged as the team's second-best weapon this postseason, and he's not backing down from the moment.

"We're not even thinking about it right now. They've won eight straight, they're the defending champions. We know it's gonna be tough to knock them off, but I think we're pretty confident we could do it," Castle said after Game 6, showing the kind of poise that's defined his breakout sophomore campaign.

Here's what gives the Spurs real hope: these two teams have already faced off five times during the 2025-26 regular season. That familiarity could be a game-changer. The Spurs have seen the Thunder's schemes, tested their defense, and learned what works. Castle, in particular, could be the key to slowing down Oklahoma City's dangerous perimeter players.

Yes, postseason experience still matters, and the Thunder have plenty of it. But the Spurs have proven they can hang with the best. With Wembanyama anchoring the paint and Castle leading the charge on the perimeter, San Antonio believes they have the formula to pull off the upset. The stage is set, the confidence is real, and the Western Conference Finals are about to get very interesting.
