SAN FRANCISCO — Klay Thompson pondered the Golden State Warriors’ current playoff situation and expressed some relief. In years past under the old format, the defending champions would have been on the brink of elimination trailing 2-0.

Thompson, Stephen Curry and Draymond Green have never been in the hole like this, down by two games — and this is a group that has practically seen it all over the past decade while capturing the franchise’s first championship in 40 years with the 2014-15 title and three more since, reaching the NBA Finals in a record five straight seasons from 2015-19 along the way.

But the upstart Sacramento Kings, coached by former top Warriors assistant Mike Brown, who helped Golden State accomplish so much, are coming to Chase Center on Thursday night for Game 3 of the best-of-seven first-round series with some serious momentum.

“Luckily, it’s first to four. It’s not the old format where it’s first to three,” Thompson said, “that would be not so much fun.”

The Warriors had gone 27 consecutive playoff series during the Curry era without falling behind 2-0. Steve Kerr hadn’t seen it, either, since he began coaching the team in 2014-15. Now, this group will need a mighty comeback and will perhaps have to do it without emotional leader Green after he stomped on Domantas Sabonis during the fourth quarter of Monday night’s 114-106 defeat at Golden 1 Center.

Sabonis was called for a technical foul for grabbing Green’s leg and Green received a flagrant-2 foul that led to an automatic ejection and possible discipline by the league.

Golden State has misfired from 3-point range — a team featuring three shooters with 200 or more 3-pointers in Curry, Thompson and Jordan Poole — and been sloppy taking care of the ball.

“We’ve just got to play with a little bit more IQ in terms of what we’re trying to do on both ends of the floor,” Curry said.

Only 26 of 334 teams that fell behind 2-0 have ever rallied to win in a best-of-seven series — a .078 percentage, according to Sportradar.

This also marks just the fifth time a defending champion has trailed 2-0 in a first-round series and all the others went on to lose. The 2012 Mavericks were swept by the Thunder 4-0; the 2007 Heat lost all four matchups to the Bulls; the 1984 76ers fell 3-2 to the Nets and the 1957 Philadelphia Warriors lost 2-0 to the Syracuse Nationals.

“The way our guys fought, they showed what they’re made of,” Kerr said. “So now it’s a matter of going home and licking our wounds a little bit. We get a little rest with a couple of days in between games and we go home and take care of our home court.”

And with Curry, Green and Thompson’s experience, they never count themselves out on the big stage.

This is a group that has regularly been challenged before and bounced back — even during this topsy-turvy regular season and its struggles. The Warriors dealt with injuries and Andrew Wiggins’ extended absences for a personal matter to avoid the play-in game and earn the sixth seed from the Western Conference.

“It’s unfamiliar territory, but we’ve been down 3-1. We’ve been up 3-1. We’ve been through everything. So we rely on our experience,” Thompson said. “We take a great off day and we recollect ourselves, and do what we do, and that’s play well at home — always.”
