After back-to-back first-round exits in the NBA Playoffs, the Dallas Mavericks and Donnie Nelson have mutually agreed to part ways on Wednesday afternoon.

“I just want to thank Donnie for his 24 years of service to this organization,” Mark Cuban said in a statement. “Donnie has been instrumental to our success and helping bring a championship to Dallas. His hard work, creativity, and vision made him a pioneer. Donnie will always be a part of the Mavs family and I wish him all the best.”

Nelson spent 24 years in the Mavericks organization. And during his tenure, the Mavericks enjoyed immense success. The Mavs made the playoffs 17 times in the last 21 years. He helped construct a roster that went to the Western Conference Finals three times, NBA Finals twice, and captured the division title three times.

Nelson also constructed the 2011 NBA Championship Mavericks roster that beat the Miami Heat in six games.

Since joining the organization, the Mavericks won 58 percent of their games and enjoyed three 60-plus win seasons.

The cause for his firing wasn’t due to underperformance. Tim MacMahon of ESPN confirmed that it had to do with lost power within the organization due to the hiring of Bob Voulgaris. According to MacMahon, the presence of Voulgaris caused internal tension among members of the front office. Tim Cato and Sam Amick of The Athletic reported on the state of the front office in a story Cuban attempted to strike down as a lie. 

In a big offseason for the Dallas Mavericks, a shift in the front office is the last thing this team needed. Now all eyes turn to who replaces Nelson’s position within the organization.
