LAS VEGAS — There was a moment during Saturday’s NBA Cup semifinal game between the San Antonio Spurs and Oklahoma City Thunder when it started to feel like Victor Wembanyama’s return was a ruse.

I looked up whether a team can violate the NBA’s player participation policy by dressing a player coming off an injury but not actually playing him. The Spurs had declared Wembanyama was coming back after missing 12 games with a calf strain. That would have been big news regardless of the game. But his first game back was going to be against the Thunder, winners of 16 straight games, in Las Vegas, with a spot in the Cup final at stake. A lot of people leading up to the week wondered if that intense of a matchup and environment was asking too much of a star coming off an injury.

Then … Wemby wasn’t playing. He didn’t start, and he didn’t play at all in the first quarter. Was this a gambit? Did he tweak something as he was warming up or stretching before a possible check-in? Were we just being impatient and paranoid? Right before the quarter break was over, with the Spurs down 31-20, we could see Wemby sitting with four teammates on the bench as Mitch Johnson coached them up. Then he stood, and the warmups came off, as the crowd erupted.

The early results were astounding.

• He played three minutes and 27 seconds, and the Spurs cut the deficit to four.

• When he checked out of the game, the Thunder went on a 14-2 run over the next four minutes and 48 seconds.

There was just no way for the Spurs to stay in this game if Wemby didn’t play big minutes. He checked back in for the final 3:52 of the first half. The Spurs finished the second quarter on a 13-0 run to cut the deficit back to three. Now we had a game, as long as Wembanyama could get enough second-half minutes to push a seemingly unstoppable force.

It’s not like he was killing it statistically. Wemby had five points, five rebounds, an assist, a steal, a block and three turnovers in seven minutes and 19 seconds in the first half. But the Spurs were plus-20 on the court in those minutes, and the eye test supported the plus/minus numbers.

Wembanyama turned it up in the second half, specifically in the fourth quarter. More importantly, the Spurs were galvanized and pushing back against the Thunder’s unsolvable defense. De’Aaron Fox scored 11 of his 22 in the third quarter, as San Antonio took the lead into the fourth. That’s when Wembanyama decided to end this winning streak and remind everybody about the problem in front of them. The Spurs won, 111-109, and will face the New York Knicks in Tuesday’s championship game.

Remember after France lost the gold medal game in the 2024 Paris Olympics? Wemby offered up a warning to the world. He said he was learning from his experiences and worried for opponents in the next couple of years. He was asked to clarify if he meant in FIBA/Olympics or in the NBA. His answer?

“Everywhere.”

Before the game against OKC, Wembanyama offered up praise of Nikola Jokić as the most complete offensive player in the world (duh) and said he thought Shai Gilgeous-Alexander or Giannis Antetokounmpo might be the best overall players. But he also mentioned he was on his way to being in that conversation and taking that title. We all figured he meant someday. Not Saturday. In the fourth quarter, he scored 15 points and helped close out the victory against the Thunder. It was shocking, and he seemed to have the building in the palm of his Jack Skellington-esque hands.

I couldn’t tell if Spurs fans traveled in big numbers or if people were just sick of the Thunder dominating everybody this season or if he won over the crowd at a neutral site. As loud as the crowd was for him, his game was even louder. Maybe we forgot about how dominant he was to start the season and the ridiculous notion that the league had solved how to defend him by using smaller, physical players. The Thunder have the best defenders in the world of that alleged prototype. He flicked each one away like ants scurrying across his hand.

This is becoming Wemby’s world, and as he warned a year and a half ago, “everywhere” should be worried.
