Rick Carlisle is the third-longest tenured head coach in the NBA. The respected bench presence has held that role with the Dallas Mavericks since May of 2008.
Unfortunately for Mavericks fans, that will not be the case when the 2021-22 season comes calling in October. In what has to be considered shocking news, Rick Carlisle informed Mavericks owner Mark Cuban that he will not return for a 14th season. This, despite the fact that he still has two years remaining on his contract.
