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 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 publicly 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.
