Mavericks Fire Nico Harrison — Patrick Dumont Explains Why

Harrison, in his fifth season as general manager, was dismissed less than a year after trading Dončić to the Los Angeles Lakers for Anthony Davis. It was a move that shocked the NBA and alienated much of the Mavericks’ fanbase.

Harrison defended the trade at the time, saying, “I believe that defense wins championships. I believe that getting an All-Defensive center and an All-NBA player with a defensive mindset gives us a better chance. We’re built to win now and in the future.”

But the gamble backfired. Davis struggled with injuries, and the Mavericks failed to recapture the spark that carried them to the NBA Finals in 2024. Dallas’ 2025-26 season began poorly, and frustration boiled over.

Dumont Explains His Decision

In his open letter, Dumont did not mince words. “No one associated with the Mavericks organization is happy with the start of what we all believed would be a promising season,” he wrote. The owner added that the results simply did not meet expectations, making it “my responsibility to act. I’ve made the decision to part ways with General Manager Nico Harrison.”

Dumont’s message avoids full accountability but fits a front office cleaning up its mess. Still, this marks a turning point for the franchise. Expectations for winning basketball now feel warranted.

“Our goal is to return winning basketball to Dallas and win championships,” Dumont said. “Our family is committed to that mission and to continuing to invest in Dallas and the Mavericks’ future.”

The Mavericks are last in the West despite being just a few hundred thousand dollars from the second apron. They will pay a repeaters tax next summer.

The Legacy of Controversy

Fans will remember Harrison’s tenure as Mavericks GM for his bold decisions—both good and bad. His decision to trade Dončić — the face of the franchise and one of basketball’s brightest stars — defined his legacy.

Despite his belief in building around defense and balance, Harrison underestimated the emotional connection between Dončić and the Dallas community. His admission that he “didn’t quite know to what level” fans valued Dončić only deepened resentment.

As boos and “Fire Nico” chants echoed through the American Airlines Center, it became clear that trust had eroded. Even the selection of top draft pick Cooper Flagg couldn’t shift the narrative.

The Path Forward for Dallas

Dumont made clear in his letter that the focus now turns to the future. “Though the majority of the 2025-26 season remains to be played, and I know our players are deeply committed to a winning culture, this decision was critical to moving our franchise forward in a positive direction,” he wrote.

The Mavericks sit at a crossroads. They still boast talent, but restoring faith among fans and players will take time. Dumont’s words — “Please join me in continuing to cheer on our players and supporting all of those who work to make this organization the best it can be” — read as both plea and promise.

For Dallas, the era of  Nico Harrison has ended. But the message from Patrick Dumont is clear: the expectation of winning basketball has returned.
