Don Nelson, the second-winningest coach in NBA history, dies at 86

Nelson is one of two coaches in NBA history to have at least 250 wins with three different franchises — Milwaukee, Dallas and Golden State — also serving as general manager for all three franchises.

SAN FRANCISCO — Don Nelson, the second-winningest coach in NBA history who won five championships as a player with the Boston Celtics, died Sunday. He was 86.

Nelson’s death was announced by the Golden State Warriors, one of the teams he coached.

Nelson is one of two coaches in NBA history to have at least 250 wins with three different franchises — Milwaukee, Dallas and Golden State — also serving as general manager for all three franchises. He was a three-time coach of the year and made the playoffs 18 times in 31 seasons. He went to the conference finals three times with the Bucks and once with the Mavericks, never winning a title.

Nelson introduced what is now known as the point forward, and his up-tempo style of offense created a buzz. He said the idea of shifting from the dominant big men of the 1970s to an offense focused on speed and the fast break came from his playing days under Celtics Hall of Fame coach Red Auerbach.
