Nico Harrison is no longer with the Dallas Mavericks, but the mistakes that he made during his time as GM still hover over the franchise. The Luka Donu010diu0107 trade is the worst, but it's not the only one. Not long after the Mavericks sent Donu010diu0107 to LA, they traded Quentin Grimes to the Sixers for Caleb Martin.
Harrison said that Dallas valued Martin more than Grimes. The Mavericks made the trade, although at the time, Martin was injured. He hadn't played in nearly a month when Dallas traded for him. To make matters worse, the Mavericks could've voided the trade after Martin's physical, but instead, Dallas was content with Philadelphia adding a second-round pick to the deal.
