Don Nelson, second-winningest NBA coach who won 5 titles as a Celtics player, dies at 86
A pioneer of 'Nellie Ball,' Nelson transitioned from a championship player in Boston to a coaching icon who reshaped the modern game through tactical innovation.
Don Nelson spent 11 seasons as a versatile piece of the Boston Celtics dynasty, collecting five championship rings. He spent the next 31 years as a head coach becoming the second-winningest leader in NBA history, yet he never won a single title from the sideline.
Nelson died Sunday at age 86. While his family stated he passed peacefully
and was surrounded by his loving family
, reporting from the Dallas Morning News via Heavy indicated he had suffered a stroke weeks earlier and had entered hospice care after relocating from Hawaii to Frisco, Texas, earlier this year.

He retired with 1,335 wins — a record that stood for nearly 12 years until it was surpassed by Gregg Popovich in March 2022. Despite the volume of victories, his coaching tenure was defined by a gap in hardware; he made the playoffs 18 times and reached the conference finals four times, but the championship eluded him as a coach.
From the Fast Break to 'Nellie Ball'
Nelson’s tactical identity was born from the mechanics of the fast break he learned under Celtics Hall of Fame coach Red Auerbach. In 2016, Nelson wrote in The Players' Tribune that without Red Auerbach teaching me the mechanics of running the fast break, none of it would have been possible
, attributing the credit for Nellie Ball
and the modern speed of the game to Auerbach.
By the 1970s, when the NBA was dominated by big men, Nelson pivoted toward a system prioritizing athleticism and spacing. This evolution occurred in two phases, according to former assistant Del Harris. The first was a defensive phase
in Milwaukee, where Nelson established himself as a top defensive coach through innovative rotations, earning two of his three Coach of the Year awards in the 1980s. The second phase was the aggressive, small-ball offensive style that became his trademark in Golden State and Dallas.
Central to this shift was the point forward
concept. By using forwards such as Marques Johnson and Paul Pressey to facilitate the offense, Nelson could surround his team with shooters and force opposing centers away from the paint. This defiance of traditional positional roles allowed him to deploy unconventional lineups, most notably the Run TMC
era in Golden State featuring Tim Hardaway, Mitch Richmond, and Chris Mullin.
Current Warriors coach Steve Kerr noted that so much of what is now commonplace in the modern NBA can be traced back to the way Nellie approached the game
.
The Architect and the Executive
Nelson operated with a rare level of institutional control, serving as both head coach and general manager for three different franchises: Milwaukee, Dallas, and Golden State. He is one of only two coaches to record at least 250 wins with three different teams.
His tenure as an executive was marked by high-impact, often controversial, personnel moves. In Dallas, he and his son, Donnie, persuaded a 20-year-old Dirk Nowitzki to leave European basketball for the Mavericks. He also developed Steve Nash into a top point guard in Dallas before Nash's MVP years in Phoenix. Later, in his final coaching season in 2009-10, he mentored rookie Stephen Curry, who said Nelson challenged him from Day 1
to be his best self on the court
.
However, Nelson's willingness to disrupt the status quo sometimes led to friction. In Golden State, a rift with rookie Chris Webber led to the player's trade and Nelson's resignation under pressure in February 1995. In Milwaukee, his departure was preceded by a public feud with owner Herb Kohl; to bypass a non-compete clause, Nelson issued an apology that he later told the Sporting News he regretted.

Beyond the court, Nelson was known for an outspoken personality. In 1986, he drove a Case IH tractor 250 miles across Wisconsin to raise money for Nellie's Farm Fund to assist struggling farmers.
His final public act of defiance occurred in 2025 during the ceremony for the Chuck Daly Lifetime Achievement Award. Miffed that the Dallas Mavericks had traded Luka Doncic to the Los Angeles Lakers — a move he called a tremendous mistake
, Nelson attended the awards ceremony wearing Doncic's signature Jordan Brand sneakers as a protest.
Nelson is survived by his wife, Joy, and seven children. A celebration of life is scheduled for August 13 in Dallas, with an ashes ceremony to follow in Maui.
