DALLAS—If the Los Angeles Lakers had any designs on luring Jason Kidd away from the Dallas Mavericks to replace fired Coach Darvin Ham, they will have to turn their attention elsewhere.
The Mavericks on Monday announced a multi-year contract extension for Mr. Kidd, one day before the team is set to open a second-round NBA playoff series against the Oklahoma City Thunder. Mr. Kidd’s name had previously surfaced in reports on the Lakers’ coaching search.
Mr. Kidd, 51, found a groove with Luka Doncic and Kyrie Irving a season after a chaotic ending to the first two months together for the Dallas superstars. The Mavericks coach has his team advancing in the playoffs for the second time in his three years in charge, with Dallas having beaten the Los Angeles Clippers in six games in the opening round.
A year ago, the Mavericks missed the playoffs after reaching the 2022 Western Conference finals in Mr. Kidd’s debut as coach for the team he helped win a championship as a point guard in 2011.
The blockbuster trade for Irving in February 2023 wasn’t the catalyst the Mavs hoped for another postseason run. Instead, the team tanked at the end of the regular season to try to preserve a draft pick, even when there were still mathematical hopes of qualifying for the play-in tournament.
Mr. Kidd, a San Francisco native who starred at St. Joseph Notre Dame High School in Alameda and collegiately at California, was the front man for all the tough questions in the final days of last season. After Mr. Kidd received a vote of confidence from then-owner Mark Cuban. Dallas kept the draft pick, and first-rounder Dereck Lively II had a significant impact as a rookie center.
“Last year, we learned a lot about character, about the team,” Mr. Kidd said. “At the time, everyone had their opinion. But understanding what the plan is internally, I thought we executed the plan. Being calm and not losing your mind or being offended of what others say turned out to be the right thing.”
Irving re-signed with Dallas, and after Mr. Cuban sold his majority stake to the casino-linked families of Patrick Dumont and Miriam Adelson, a late-season surge lifted the Mavs to fifth in the West at 50–32 this season.
Terms of Mr. Kidd’s deal weren’t released. Doncic and Irving are under team control together for one more season. Irving has a player option in his contract for 2025–26, Doncic the following season.
“We are excited to have Coach Kidd continue to lead our team throughout the coming years with this well-earned contract extension,” said Mr. Dumont, who is the team’s governor while Mr. Cuban has the role of alternate governor. “We are looking forward to his leadership in continuing to build and grow this already great franchise.”
A Hall of Famer as a player, Mr. Kidd ended his career second on the NBA’s all-time list for assists, behind John Stockton. Mr. Kidd went into coaching immediately upon retirement, leading the Brooklyn Nets to the second round of the playoffs in his first season in 2013–14 before the Milwaukee Bucks hired him away from the Nets.
The Bucks fired Mr. Kidd in the middle of his fourth season—after two first-round playoff exits the first three years—and he spent two years as an assistant with the Lakers, including when they won the NBA title in the 2020 playoff bubble.
Mr. Kidd, who replaced Rick Carlisle in Dallas, has a 140–106 regular-season record with the Mavs and is 323–296 overall.
After Mr. Kidd and NBA Finals most valuable player Dirk Nowitzki led the Mavs to the 2011 title, they didn’t win another playoff series until beating the Utah Jazz in the first round under Mr. Kidd two years ago. Now Dallas has three series victories in three seasons.
“Jason brings a wealth of experience and expertise to this role, which cannot be duplicated,” General Manager Nico Harrison said. “He has earned the trust and respect of our players and that of so many across the league.”
