Dallas Mavericks owner Mark Cuban bought the team in 2000. They made the playoffs in his first full season leading the organization which snapped a decade long drought. In his 19 years at the helm, the Mavs have missed the postseason four times.
Cuban has had an incredibly successful run including reaching the peak by winning the championship in 2011. Having an all-time great player in Dirk Nowitzki helped. The Mavs have missed the playoffs three straight years, but Luka Doncic appears to have them back on track in Cuban’s 20th full season as owner.
