The Dallas Mavericks have been on a downward spiral since the start of the 2025-2026 NBA season. The team currently holds the 14th spot in the Western Conference standings, winning only three of its first 10 games this season. This came after Mavericks general manager Nico Harrison declared last April that they would be contending for a championship this season. “You’ll see next year when our team comes back, we’re going to be competing for a championship," he said. His reputation among Dallas fans continues to spiral down after the team's early-season collapse, earning him calls for his firing during games. Here are five damning reasons why the team should fire Harrison:5 Most Damning Reasons to Fire Nico Harrison Amid Mavericks’ Astonishing Collapse 1.) His words do not reflect the team's performance on the courtPromising about the Mavericks' resurgence is one thing. Providing a competitive squad on the court is another. Apparently, Harrison has only delivered on the former. Their 3-7 record says a lot about the Mavericks' state under Harrison this season. Their wins only came against non-contending teams such as the Toronto Raptors, Indiana Pacers, and the Washington Wizards, far from his promises of being a championship contender. 2.) Mavericks fail to build around Anthony DavisThe team has yet to build a competitive roster around Anthony Davis this season. Most of the squad are remnants from the Luka Doncic era, such as Klay Thompson, Danuel Gafford, and Dereck Lively III. While Cooper Flagg is seen to be a promising piece around Davis, the Mavericks failed to create enough floor spacing around Davis in the past offseason. Davis was the team's biggest acquisition in the blockbuster trade that brought their former franchise superstar Doncic to the LA Lakers.3.) Injury bug continues to bother the MavericksSince trading Doncic, the Mavericks have seen a pattern of injuries throughout their roster, including Kyrie Irving, PJ Washington, Lively, Gafford, and Anthony Davis. While this is not directly impacted by Harrison's decision-making as a general manager, this is an alarming pattern under him. 4.) Fans have been fed upDallas fans have been protesting and chanting for Harrison's firing since last season after he traded Doncic just a year after he led them to the NBA finals. Letting him stay with the franchise could be a disservice to the diehard Mavericks hopefuls who have been supporting the squad. 5.) Dallas needs a fresh startThe Mavericks franchise simply needs a fresh start, which could only be started by the team's firing of Harrison. Letting go of Harrison would mean a new chapter for the Mavericks, allowing them to move forward following the pain of trading Doncic.
