NBA Commissioner Adam Silver lauded Nelson's "fearlessness, ingenuity and deep conviction," stating that his impact on the sport will be felt for generations. The Golden State Warriors, where Nelson had multiple stints as coach, called him "one of the most innovative and influential coaches in NBA history and an iconic figure in Warriors history." They highlighted his visionary approach and willingness to challenge conventional thinking, which paved the way for future players and coaches.

Though Nelson never won an NBA title as a coach, he led the Warriors to the playoffs multiple times, including a memorable first-round upset in 2007. He also guided the Bucks to seven consecutive Central Division titles and helped build the Mavericks into contenders. Nelson retired from coaching in 2010 after his second stint with the Warriors. In recognition of his career, he received the Chuck Daly Lifetime Achievement Award from the National Basketball Coaches Association in June 2025.
