Mavericks are also one of just six franchises to win 60 games or more three times in a five-year span. Stemming from the efforts made during Nelson's tenure, the Mavericks reached the playoffs for ten consecutive seasons, reached the Western Conference Finals three times, and advanced to the NBA Finals twice, winning their first NBA Championship in 2011. Nelson acquired the core group of players on the 2011 championship Mavs roster through key trades and success in the NBA draft. All-Star Tyson Chandler, 2008–09 Sixth Man of the Year Jason Terry, Hall of Fame point guard Jason Kidd, four-time All-Star Shawn Marion, two-time All-Star Caron Butler, and Brendan Haywood were acquired through trades. Nelson was also responsible for adding 2007 MVP, 2011 NBA Finals MVP, and 14-time All-Star Dirk Nowitzki via trade on NBA draft night. On previous teams, Nelson played a role in trading for players such as two-time MVP Steve Nash and All-Star/Sixth Man of the Year Antawn Jamison, as well as acquiring future All-Stars Devin Harris and Josh Howard via the draft. The key pieces of the current Mavericks roster were once again assembled through impressive trades and Draft night success orchestrated by Nelson.

Nelson has the Mavericks well-positioned for success and a rapid rebuild with two young cornerstones following the retirement of Mavericks legend Dirk Nowitzki. Nelson has earned a reputation in basketball as arguably the greatest international scout of all time considering his groundbreaking involvement in Eastern Europe (Marčiulionis) and China (Zhizhi) combined with his role in acquiring future MVP's Steve Nash (Canada) and Dirk Nowitzki (Germany), All-Star Porziņģis (Latvia), and Rookie of the Year Luka Dončić (Slovenia). He also famously advocated for the Mavericks to draft future MVP Giannis Antetokounmpo (Greece) in 2013, only to be rebuffed by owner Mark Cuban. Nelson also served as an assistant coach in 2000, when Mark Cuban purchased the team and was an interim coach filling in for his father on multiple occasions between 2000 and 2002. As the Mavericks established an NBA G League (D-League) team in Frisco, Texas, a suburb north of Dallas, Nelson was named co-owner. The Texas
