DALLAS — Klay Thompson is moving on from the Golden State Warriors, with the four-time league champion agreeing to join the Western Conference champion Dallas Mavericks and change franchises for the first time in his 13-year NBA career, two people with knowledge of the decision said Monday.

ESPN and The Athletic first reported the multiteam deal which, as currently constructed, will be executed as the sign-and-trade of a three-year, $50 million contract involving the Warriors, Mavericks and Charlotte Hornets, said the people, who spoke to The Associated Press on condition of anonymity because the agreement has not been announced. One of the people who spoke to the AP said final trade terms were still being worked out.

Thompson is sixth on the NBA’s all-time 3-pointers made list with 2,481, behind Reggie Miller (2,560), Damian Lillard (2,607), James Harden (2,940), Ray Allen (2,973) and Thompson’s now-former “Splash Brother” with the Warriors, Stephen Curry, and his 3,747 career makes from beyond the arc.

There were indications last season that Thompson and the Warriors might be headed toward a breakup.

Thompson came off the bench 14 times — not much in the grand scheme of things considering he played 77 games, but those were his first appearances as a reserve since his rookie season of 2011-12. He shot 38.7% from 3-point range, the second-worst of his career. He averaged 17.9 points, the third-lowest of his career. He wasn’t always in the finishing lineup and the season — and his Warriors career — ended with a 0-for-10 shooting performance against Sacramento in a play-in tournament loss.

Thompson — a five-time All-Star and two-time All-NBA selection who missed two entire seasons with injuries — took a long look around the court after that game, soaking in the scene just in case it would be his final time playing with the Warriors. Turns out, it was. And now he’ll join a Dallas team that just went to the NBA Finals as a shooter brought in to help Luka Doncic and Kyrie Irving.

The Hornets were planning to acquire guard Josh Green as part of the deal, giving up two second-round draft picks. The 15th overall pick in the 2020 draft, Green has spent all four of his NBA seasons with the Mavericks and averaged 8.2 points, 3.2 rebounds and 2.3 assists this past season.

The league’s moratorium on signings is lifted on Saturday.

Maxey, Harris, Hartenstein Land Deals

They were all undervalued on some level when they entered the NBA. None was a lottery pick, some weren’t even first-round picks and they didn’t have the label of can’t-miss prospects.

That was then. Monday was a very different story for Tyrese Maxey, Derrick White, Isaiah Hartenstein, Tobias Harris, Isaiah Joe and Aaron Wiggins — who are about to sign deals worth a combined $565 million.

All were confirmed to the AP by people with knowledge of the negotiations for the players involved.

Maxey, an All-Star this past season, agreed in principle to a five-year, $204 million extension that keeps him with the Philadelphia 76ers and set to play alongside Joel Embiid and soon-to-be-signed Paul George.

The 76ers, like the rest of the league, are chasing the Boston Celtics, who made a big move by agreeing with guard Derrick White on a four-year extension worth around $125 million. White averaged 15.2 points and 5.2 assists for the NBA champions this past season.

Hartenstein, a center coming off a breakout year, is leaving New York for Oklahoma City on an $87 million, three-year deal that includes an option. The Thunder — the No. 1 seed in the Western Conference this past season — also finalized extensions with Joe ($48 million) and Wiggins ($47 million).

And Harris is going to Detroit on a two-year deal worth $52 million, a move first reported by ESPN and one that will give the young Pistons an experienced veteran in the room as they continue their rebuild under newly hired coach J.B. Bickerstaff.
