BOSTON — With the Golden State Warriors clinching their fourth title in eight years on the strength of their 103-90 closeout win over the Boston Celtics in Game 6 of the NBA Finals on Thursday night at TD Garden, here are the key takeaways from a game where the Warriors turned it around early and never lost control:

Put a ring on it: Despite the injuries, absences and setbacks this season presented, the Warriors did it again. Few thought Golden State would be in this position at the start of the season. And the man who led them back up the mountaintop, and to victory in Game 6, was someone who has been there since the beginning.

Stephen Curry bounced back from his Game 5 struggles in a major way, scoring 34 points and knocking down 6 of 11 3-pointers. Nine of those points came in the third quarter, 13 in the fourth. He also finished with seven rebounds and seven assists in 40 minutes. The Warriors didn’t get a typical Game 6 performance out of Klay Thompson on Thursday night. Thanks to Curry, they didn’t need it.

As the final second ticked away in Game 6, Curry embraced his dad, Dell, on the far baseline, then collapsed onto the hardwood in tears. And here’s another moment: Curry held up the Bill Russell NBA Finals MVP trophy for the first time in his career in the city where Russell and the Celtics ruled. That’s the stuff of legends.

“It means we won,” Curry said of winning the award. “It means we took advantage of the opportunity to get back here. ... At the end of the day it’s about what we do on the floor. Ain’t gotta talk about it — you just gotta go do it — and that’s what this is about.”

Curry said winning this fourth time wasn’t like the Warriors’ previous titles, and stands out from their previous three.

“Just combining our championship pedigree and our experience with some fresh energy and some guys who are really hungry to take the next step,” Curry said. “But we built this for 10, 11 years, and that means a whole lot when you get to this stage, because you know how to win, and everybody who’s been a part of this knows what it’s about. But this one hits different.”

Thompson was over the moon, completing his comeback season with playing for another Warriors champion.

“I knew it was a possibility, but to see it in real time? Holy cannoli. This is crazy,” Thompson said.

Green gets even: TD Garden got the best of Draymond Green in Game 3. He showed signs of resurgence in Games 4 and 5. But in a close-out Game 6 on the road, when the Warriors absolutely needed him at his best, he delivered.

The TD Garden crowd didn’t have much to say to Green this time around. There was little they could say, really. Instead, it was Green doing the barking on Thursday night. And his bite was good for 12 points, 12 rebounds and eight assists in 42 minutes — his best performance in these Finals, by far. The Warriors were plus-16 with Green on the court.

“This fan base gave me a hard time,” Green said afterward. “A really hard time. And to come here and get a win, it’s awesome. I appreciate this fan base. They brought incredible energy. Gotta give kudos to them, but we did what we do. Welcome back to the Warriors’ Invitational, baby. It’s what we do!”

Shortly after Andrew Wiggins’ 3-pointer made it a 99-86 game late, Green jogged back down the court using both hands to wave goodbye to the crowd. For a moment, some thought Green wasn’t focused enough in this series because of his podcast off the court.

Just wait until his haters hear his latest episode.

Championship runs: A Jayson Tatum 3-pointer with 9:55 left in the first quarter gave the Celtics an early 12-2 lead, and it appeared as if the Warriors were well on their way to another bad road playoff loss.

At that point, Golden State fans back in the Bay Area were probably thinking, “We’ve seen this movie before,” remembering the Warriors’ inability to close series on the road in the previous three rounds. TD Garden was rocking. The road team was on its heels. Then Steve Kerr made an adjustment, replacing starter Otto Porter Jr. in the lineup with Kevon Looney. And suddenly the Warriors’ championship mettle rose to the surface.

Boston’s early 12-2 lead disappeared faster than it was built. From the moment Looney checked in with 8:45 left in the first quarter, the Warriors outscored the Celtics 25-10 to close the period, then opened the second quarter on a 10-0 run to take a 37-22 lead with 10:13 left in the half. Golden State went on a 21-0 run spanning the end of the first quarter and the beginning of the second. That run took the TD Garden crowd out of the game, at least for the time being.

While Boston would battle back in the second quarter to make it an eight-point game with 6:44 left, Golden State responded with a 15-8 run to build a 54-39 lead at halftime. The Warriors then went on a 20-11 run over the first 8:19 of the third quarter for good measure, building their largest lead of the night at 22.

As it turned out, those runs created just enough separation for the Warriors to leave TD Garden with a championship. After a long Curry 3-pointer pushed Golden State’s lead to 22, he celebrated by pointing at his ring finger. That disrespect ignited an impressive run for the Celtics, as they roared back to make it a 10-point game entering the fourth quarter.
