The 2007–08 campaign saw another first-round playoff exit for Nowitzki and the Mavericks. Despite a mid-season trade that brought veteran NBA All-Star Jason Kidd to Dallas, the Mavericks finished seventh in a highly competitive Western Conference. Nowitzki averaged 23.6 points, 8.6 rebounds, and a career-high 3.5 assists for the season. In the playoffs, they faced rising star Chris Paul's New Orleans Hornets, and were eliminated in five games. The playoff loss led to the firing of Avery Johnson as head coach and the eventual hiring of Rick Carlisle. The few positive highlights that season for Nowitzki were his first career triple-double against the Milwaukee Bucks on February 6, 2008, with 29 points, 10 rebounds, and a career-high 12 assists, and on March 8, 2008 (34 points against the New Jersey Nets), when he surpassed Rolando Blackman with his 16,644th point to become the Mavericks' all-time career points leader.
