DALLAS (AP) New Mavericks coach Jason Kidd and general manager Nico Harrison were introduced Thursday by their new boss, who called it "a new chapter" for a franchise that had not changed GMs under his 21-year ownership and has not won a playoff series since winning the 2011 NBA championship.

Owner Mark Cuban said the need for "a new voice" motivated him to change GMs for the first time.

"The league has changed in the 21 years since I've been here," he said. "Players have changed. How you build a championship team has changed. Sometimes you just have to look to have a different tool set."
