However, after watching Kawhi Leonard sway a contest in his team's favor for the second consecutive game, the future Hall of Fame coach couldn't help himself.
"He's ridiculous," Popovich said after Leonard sparked the Spurs to a 102-94 victory over the Sacramento Kings on Thursday, spoiling the regular-season opening of the Kings' new Golden 1 Center. "The stuff he does, it changes games."
Leonard scored 30 points and showed the Kings during one 100-second stretch that the more things may be changing for them, the more San Antonio's success against them would stay the same.
Leonard stole the ball three times over four Sacramento possessions, turning one of them into his own layup, another into two free throws, and the third into a layup for teammate Dewayne Dedmon. On successive possessions, he swiped the ball straight out of the hands of Sacramento guard Ben McLemore.
That flurry highlighted a 24-5 run for San Antonio that bridged the third and fourth quarters and led to San Antonio's seventh consecutive victory against Sacramento. It also gave the Spurs their first 2-0 start since 2013.
"He just grabbed it and took it twice in a row," Popovich said. "You don't see too many people doing that."
Leonard is starring on offense, too. He scored 35 points and made all 15 of his free throws in San Antonio's season-opening, 129-100 rout of the two-time defending Western Conference champion Golden State Warriors. His 65 points in the Spurs' first two games have come on 21-of-42 shooting.
"He took over on defense," Dedmon said. "He's the two-time Defensive Player of the Year. That's what he does."
What the Kings have done mostly over the past decade is lose. But a 113-94 road rout of the Phoenix Suns on Wednesday and the opening of their sparkling 17,500-seat arena seems to have changed the outlook. The Kings led for most of three quarters and responded to San Antonio's game-changing run by using a 12-2 surge to momentarily tie the contest 83-83 in the final quarter.
In the end, the Kings failed in their bid to open the season with consecutive victories for the first time since 2003. Still, they seemed much improved from the 33-49 squad a season ago that missed the playoffs for the 10th consecutive year.
"It's early in the season, and it was a great team," Gay said. "It was a good test for us. We just need to stick with it."
The opening of the $557 million stadium stirred up emotions for fans who nearly watched the Kings leave for Seattle in 2011, and it brought out several dignitaries.
NBA commissioner Adam Silver was in attendance, as was the man he replaced, former commissioner David Stern. Mayor Kevin Johnson, also instrumental in saving the Kings for Sacramento, also was on hand. So was Chris Weber, a stalwart in the team's glory days of late 1990s and early 2000s.
The Kings made the home crowd happy early, jetting to a 54-43 second-quarter lead en route to a 57-53 halftime advantage. However, a 3-for-17 shooting effort in the third quarter ultimately doomed them.
