Here they go again.

For the third straight year, it’s Cleveland and Golden State in the NBA Finals. The 2016 champions versus the 2015 champions . The first “threematch” — rematch of a rematch — in league history. It’s the matchup most expected, the matchup most predicted, and probably the matchup the Cavaliers and Warriors wanted as well.

Let the hype, and the waiting, begin: Game 1 isn’t until June 1.

“I’ve been very blessed the last few years to be a part of this league and play on the big stage,” said Cleveland star LeBron James, who has now reached the Finals for the eighth time — including each of the last seven years. “But we’re going to enjoy this for a couple more days before we have to lock in on that juggernaut out west.”

The Cavaliers and Warriors split their two meetings this season, both winning at home. Cleveland won by one on Christmas Day, Golden State prevailed by 35 on Jan. 16.

Golden State led the league with 67 wins this season and is a staggering 27-1 in its last 28 games — including a perfect 12-0 in the Western Conference playoffs, the first time a team has gone this deep into an NBA postseason without losing. Cleveland, which seemed sleepy at times in the regular season, went 12-1 in the Eastern Conference playoffs that ended with a win over Boston on Thursday night.

“Playing in this league, you can’t take anything for granted,” Warriors guard Stephen Curry said. “Thirty teams suit up every year trying to get to this point, and only two teams do. So you have to appreciate it. … We need to understand the privilege that we have and the opportunity that we have to play in the Finals again, to have the opportunity to win a championship.”

Already, the back-and-forth is underway.

Cleveland coach Tyronn Lue was quoted earlier this week saying he thought Boston’s offense was “harder to defend” than Golden State’s. Countered Golden State acting coach Mike Brown, when asked about it Thursday: “That’s his opinion. It’s cute.”

And there will be reminders of the Halloween party that James threw for the Cavaliers last fall, with “3-1 Lead” — a nod to what the Warriors lost in last year’s Finals — prominently displayed on the drum set.

Much more of that sort of that will likely follow over the next week, filling time before Golden State plays host to Game 1. But there’s also a clear respect level between the clubs as well.

“The best team in our league the last three years,” James said of the Warriors. “And they’ve added an unbelievable player in Kevin Durant this year. So it makes it even more difficult. They’re going to challenge us a lot, offensively, defensively, mentally, physically. We have to be ready for the challenge.”

For James, the Finals are an annual rite.

For Durant, this trip ends a five-year wait.

Durant’s only other time in the Finals was 2012 when he was with Oklahoma City. The Thunder lost to Miami in five games, a series that made James a champion for the first time.

At the very moment where the clock ran out in that series, the person James was embracing was Durant — telling the then-Thunder star, his offseason workout partner at the time, how proud of him he was.

“Hopefully,” James said that night, “I don’t continue to have to run into him.”

They’ll collide again, starting next week.

Durant’s decision to leave the Thunder for Golden State as a free agent last summer meant the Warriors went from mere overwhelming favorites to win the West again to super-duper-overwhelming favorites to win the West again. They got a big scare in late February when Durant had a left knee injury, but he’s back and the Warriors have rolled since.

“It’s a little different, definitely. I can’t lie,” Durant said, when comparing the 2012 Finals trip to this one. “I went when I was 23 years old, and it felt like the Western Conference Finals was almost like the championship. Just getting to that point, you know how hard it is and how much work you put in to start the season. So it’s a little different now, obviously. We have a bigger goal in mind.”

The storylines are many. Can James win his fourth ring? Can Durant win his first? Will the Warriors be haunted by letting last season’s 3-1 lead slip away? Will they become the first team in NBA history to go undefeated in a postseason? How will Golden State guard Kyrie Irving? How will Cleveland try to contain Curry?

There’s also the irony that Brown, the first coach who took James to an NBA Finals in 2007 — Cleveland was swept by San Antonio — will now coach against him, likely in the same leading role he’s had for Golden State since head coach Steve Kerr was forced to take a break because of continued problems with his surgically repaired back.

“I don’t care who you’re playing, to make it to the NBA Finals, to win your conference finals, it’s a big task,” Brown said.

The biggest task awaits.
