In his 15 seasons as majority owner of the Dallas Mavericks, Mark Cuban's team has made the playoffs in all but one season and captured a championship in two Finals appearances.
While there has been a collection of mistakes made along the way, as with the management of any professional sports franchise, the one glaring error on Cuban's resume was letting Steve Nash walk as a free agent in 2004, paving the way for his back-to-back MVP seasons with the Phoenix Suns.
But, according to Cuban, losing Nash wasn't the worst personnel decision of his Mavs tenure.
#Mavs owner Mark Cuban said acquiring Lamar Odom in 2011 "was by far the worst'' personnel move he's ever made.

Consider how massive a failure a move must be to trump losing a future MVP, and then recall Odom's lone season in Dallas.
Coming off a career year with the Los Angeles Lakers in 2010-11, Odom was sent to the defending champion Mavericks for a trade exception and a future first-round pick, which eventually turned into Mitch McGary.
Odom, who reportedly clashed with Cuban, averaged 6.6 points, 4.2 rebounds and 1.7 assists on a pitiful 35-25-59 shooting line with Dallas. Odom and the Mavs eventually agreed to part ways before the season was even complete.
