The New York Knicks haven’t won an NBA championship since 1973. The Indiana Pacers won their most recent title that year — in the ABA. The Oklahoma City Thunder franchise has one title in its history, that coming in 1979 when the team called Seattle home. And the Minnesota Timberwolves have never even been to the NBA Finals.

Meet the NBA’s final four.

The Thunder booked their ticket Sunday. Shai Gilgeous-Alexander scored 35 points, Jalen Williams added 24 and the Oklahoma City rolled into the Western Conference finals, beating Denver 125-93 in Game 7.

The top-seeded Thunder will host the sixth-seeded Minnesota Timberwolves starting Tuesday. It’s Oklahoma City’s first trip to the conference finals since 2016.

Oklahoma City won a league-best 68 games in the regular season.

Three-time MVP Nikola Jokic had 20 points, nine rebounds and seven assists for the Nugget, who were up by 11 points in the first quarter. But OKC took the lead early in the second and led 60-46 lead at the break.

The Knicks and Pacers will square off in the Eastern Conference finals starting Wednesday.

When Commissioner Adam Silver hands one of those teams the Larry O’Brien Trophy next month, it’ll mark a league first — seven championship franchises in a seven-year span.

There hasn’t been a back-to-back NBA champion since Golden State in 2017 and 2018. From there, the list of champions goes like this: Toronto in 2019, the Los Angeles Lakers in 2020, Milwaukee in 2021, Golden State in 2022, Denver in 2023 and Boston last season.

It’s the longest such run of different champions in NBA history; MLB, the NHL and the NFL have all had longer ones, and not too long ago, either.

But for the NBA, this is different. The league wanted unpredictability, especially after four consecutive Cleveland vs.-Golden State title matchups from 2015 through 2018.

And things have been highly unpredictable since. No matter what the Finals matchup is this year, the NBA will be seeing 11 conference-champion franchises in the span of seven seasons.

“We’ve still got eight more wins to achieve our ultimate goal,” Minnesota coach Chris Finch said. “We’ve still got two more series. We’re only halfway there.”

The season is over for 26 of the NBA’s 30 clubs. But the fun stuff is just starting.

“You’ve got to have big dreams,” Pacers coach Rick Carlisle said. “You don’t know how often you’re going to be in this position.”

Indeed, the championship window for teams doesn’t seem to be staying open as long as it did in the past.

Boston was a huge favorite to win its second straight title; the Celtics didn’t get out of Round 2.

“Upset or not, whatever it is, we beat a great team,” Knicks guard Jalen Brunson said. “They obviously lost a huge piece ... but they’re still a great team.”
