Rick Carlisle resigns as head coach of Dallas Mavericks after 13 seasons

June 17 (UPI) -- Rick Carlisle has resigned as head coach of the Dallas Mavericks, ending his 13-year tenure with the organization.

"After a number of in-person conversations with [owner] Mark Cuban over the last week, today I informed him that I will not be returning as head coach of the Dallas Mavericks," Carlisle said in a statement Thursday. "This was solely my decision. My family and I have had an amazing 13-year experience working with great people in a great city."

Carlisle's exit comes after the departure of longtime president of basketball operations Donnie Nelson on Wednesday, removing two of the franchise's key figures from its 2010-11 championship team.

The 61-year-old Carlisle said it was an "honor to work alongside" multiple members of the Mavericks organization, specifically naming Cuban, Nelson, CEO Cynt Marshall, vice president of basketball operations Michael Finley, assistant general manager Keith Grant and former players Dirk Nowitzki and Jason Kidd.

"Dallas will always be home, but I am excited about the next chapter of my coaching career," Carlisle said.

Carlisle has compiled an 836-689 career record in his coaching career, having been the head coach of the Detroit Pistons and Indiana Pacers before arriving in Dallas in 2008. He was the NBA's third-longest-tenured coach behind only Gregg Popovich of the San Antonio Spurs and the Miami Heat's Erik Spoelstra.

During his 13 seasons in Dallas, Carlisle had a 555-478 record, setting a franchise mark for wins. He notched a 33-38 postseason record with the Mavericks, who have failed to advance past the first round since their NBA title run a decade ago.

"Rick informed me today about his decision to step down as head coach," Cuban said in a statement. "On top of being a tremendous basketball coach, he was also a friend and a confidant. Rick helped us bring the Larry O'Brien Trophy to Dallas and those are memories I will always cherish.

"I want to thank Rick for all he gave this franchise and this city. We wish him all the best."

Cuban said the Mavs will look for a new head of basketball operations before conducting a coaching search.

League sources told ESPN that the tension between Carlisle and 22-year-old star Luka Doncic had become a significant concern within the organization. Doncic had multiple public disagreements with Carlisle this season, such as making gestures on the court when he disagreed with a decision or yelling at Carlisle in front of coaches and players.

Doncic has a strong relationship with longtime Mavericks assistant Jamahl Mosley, who is a possible candidate to replace Carlisle.
