Don Nelson, a Hall of Fame coach and former Boston Celtics player, died on Sunday at an assisted living facility in Frisco, Texas. He was 86.
Nelson spent almost 50 years in the NBA. His career covered both playing and coaching. He became one of the league’s winningest coaches and built a lasting name through his work with several teams.
His health declined in the weeks before his death. Nelson suffered a stroke about three weeks earlier, according to his granddaughter, Christie Nelson Armstrong. His condition later became worse.
Nelson’s death ends the life of a major figure in NBA history. He was known for his strong mind, new ideas and long service to the game.
His final years came after a career that reached far beyond the court. Nelson had already earned a place in basketball history long before his health began to fail.
As a player, Nelson was not seen as a natural star. He was an undersized small forward and was not known for speed or great athletic skill. NBA teams twice waived him before he found a home with the Celtics in 1965.
Boston gave Nelson the chance to build a strong career. He became part of one of the greatest teams in league history.
Nelson won five NBA titles as a player with Boston. He often came off the bench and gave the team a strong lift. His jump shot became one of his best skills.
His most famous moment as a player came during the 1969 NBA Finals against the Los Angeles Lakers. He hit a key basket that helped make the series memorable.
After his playing career ended, Nelson moved into coaching. That second career became even more important to his place in NBA history.
Nelson coached for 31 years. He led the Milwaukee Bucks, Golden State Warriors and Dallas Mavericks. He also spent a short time with the New York Knicks.
His coaching career made him one of the most successful coaches in NBA history. He was willing to test new ideas and use players in ways that were not common at the time.
Nelson became known as Nellie. His teams often played with speed and space. He also used smaller lineups to create problems for bigger teams.
His work helped influence the way basketball developed. Many of his ideas later became common in the NBA.
Nelson’s final years followed a life filled with major achievements. He had already entered the Basketball Hall of Fame. He also remained linked to the Celtics, the team that gave him his first major chance in the NBA.
His life showed a rare path through professional basketball. He first succeeded as a player despite doubts about his size and athletic ability. He then found even greater success as a coach.
Nelson also spent many years around young players and new teams. His willingness to try new ideas made him an important voice in the sport.
The news of his death brings an end to a career that crossed several generations of basketball. Few people in the NBA have seen so much change in the game from both sides of the bench.
Nelson leaves behind a record that includes five NBA titles as a player, a long coaching career and a place among the league’s most successful coaches.
His final years were quiet compared with the many decades he spent in the NBA. Yet his influence on the sport remains clear.
Don Nelson’s death marks the end of a long basketball life. His career began with questions about whether he was good enough to stay in the NBA. It ended with his name firmly placed among the game’s most respected figures.
