Don Nelson was a basketball lifer. He had an interesting career as a player, but he became more interesting as a coach.
Donald Arvid Nelson was born on May 15, 1940 in Muskegon, Michigan, right across Lake Michigan from Milwaukee. He grew up in a farm outside Sherrard, Illinois, in the Quad Cities region that straddles the Mississippi River in Illinois and Iowa. He graduated from Rock Island High School, 2 years ahead of Ken Bowman, a center who helped the Green Bay Packers win the 1st 2 Super Bowls.
Milton "Sharm" Scheuerman was the head basketball coach at the University of Iowa, and a Rock Island High graduate, and recruited Nelson. He also recruited Brooklyn high school star Connie Hawkins, but Hawkins was caught up in a gambling scandal. Despite never being charged with a crime, Hawkins was kicked out of school, and banned from the NBA, playing in the ABL, AAU ball, and the ABA before his ban was lifted.
At a time when the NCAA Tournament only invited 24 teams, and from a conference only the Champion, Iowa finished 2nd to Ohio State team of Jerry Lucas and John Havlicek in 1961, and missed the Tournament. "If Connie had stayed, we would have had a great team," Nelson said. "I feel we could have edged out Ohio State my junior and senior years." Nelson was named a 3rd-term All-America in 1962.
He was taken by the Chicago Zephyrs in the 3rd round of the 1962 NBA Draft. After 1 season, he was waived, claimed by the Los Angeles Lakers. They reached the Finals in each of his 2 seasons with them, but lost both to the Boston Celtics.
He was released, but the Celtics must have liked what they saw, because they signed him as a free agent. He helped them win the 1966, '68 and '69 NBA titles. He remained with them through their rebuilding, and helped them win the title again in 1974 and '76, at which point he retired as a player. In 1973, he was inducted into the Illinois Basketball Coaches Association Hall of Fame as a player. The Celtics retired his Number 19 in 1978.

His son Donnie remembers the family sitting in a Maid Rite restaurant in Moline, Illinois (one of the "Quad Cities," along with Rock Island, and Davenport and Bettendorf, Iowa), and Don saying he had three choices: sell cars, become an NBA referee, or accept an assistant's job under Milwaukee coach Larry Costello. They voted 5–0 for the Milwaukee job, which paid $25,000.
The Bucks got off to a 3-15 start in 1976-77, and Costello, despite having led the Bucks to the 1971 NBA Championship and the 1974 NBA Finals, which they lost to "Nellie" and the Celtics, was fired. Nelson was named head coach. At the end of the season, only 37 years old, he was also given the general manager's job. He built a team around speed, and not caring about height, often letting shorter but faster players guard taller but slower ones.
The result of "Nellie Ball" was 7 straight Division titles: 1980 in the Midwest Division; then, after an NBA realignment, 6 in the Central Division, in 1981, '82, '83, '84, '85 and '86. He was named NBA Coach of the Year in 1983 and '85. But the closest he could get to a title was reaching the Eastern Conference Finals 3 times, in 1983, '84 and '86.
In 1985, Jim Fitzgerald sold the Bucks to department store mogul and future U.S. Senator Herb Kohl. Nelson didn't get along with him, but he had gotten along with Fitzgerald. In 1986, Fitzgerald bought a different NBA team, the Golden State Warriors. After a season as a broadcaster, Nellie accepted the head coaching job with the Warriors, and even bought an ownership stake.
Again using a run-and-gun style, he coached them for 6 seasons, building an offense known as Run TMC, after the rap group Run-DMC, for Tim Hardaway Sr., Mitch Richmond and Chris Mullin. He was awarded a 3rd Coach of the Year trophy in 1992. But he only won 2 Playoff series, and resigned during the 1994-95 season.
He was hired to coach the New York Knicks for 1995-96, replacing Pat Riley. But Riley had built a defense-oriented team, and Nellie Ball didn't work with them. When he recommending trading the team's marquee player, Patrick Ewing, so that enough salary cap space would be available to make an offer to Shaquille O'Neal, who was unhappy with the Orlando Magic and wanted to play in a big market, that was the last straw for Knicks management: He was canned on March 8, 1996. Shaq ended up going to the Los Angeles Lakers.
In 1997, he was hired as head coach and general manager of the Dallas Mavericks. It took him 4 seasons to turn them from dreadful to a Playoff team, and in 2003, the Mavs won the Midwest Division and reached the Western Conference Finals. But that was as close as he would get, and he resigned late in the 2004-05 season.
In 2006, Mullin, now the Warriors' GM, brought Nelson back to Oakland. He won 16 of their last 21 games, squeezing into the Playoffs as the 8th seed, and upset his former team, the Mavericks, in the 1st round. This was only the 3rd time an NBA 8th seed had beaten a 1st seed, and the 1st time since the 1st round went to a best 4-out-of-7.
But he never got them into the Playoffs again. On April 7, 2010, the Warriors beat the Minnesota Timberwolves, 116-107 at the Target Center in Minneapolis, giving Nelson his 1,333rd career coaching win, surpassing Lenny Wilkens for the most in history. He held that record until 2022, when he was surpassed by Gregg Popovich. He retired at the end of that season, with a record of 1,335-1,063 (.557).
In all, he coached 17 members of the Basketball Hall of Fame. With the Bucks: Alex English, Bob Dandridge, Sidney Moncrief, his former Celtics teammate Dave Cowens, Nate "Tiny" Archibald, Bob Lanier and Jack Sikma. With the Warriors: Chris Mullin, Ralph Sampson, Mitch Richmond, Tim Hardaway, Šarūnas Marčiulionis and Chris Webber. With the Knicks: Patrick Ewing. With the Mavericks: Steve Nash, Dirk Nowitzki, Dennis Rodman briefly, and Hardaway again.
He coached 6 of the 9 players to have had their uniform numbers retired by the Bucks: 10, Dandridge; 4, Moncrief; 16, Lanier; 32, Brian Winters, 2, Junior Bridgeman; and 8, Marques Johnson. Only 1 of his Warriors players had his number retired: Mullin, 17. Ewing had his Number 33 retired by the Knicks, and Nowitzki had his Number 41 retired by the Mavs.
He was elected into the Iowa Sports Hall of Fame in 1983, the Quad City Sports Hall of Fame in 1987, the University of Iowa Athletics Hall of Fame in 1989, and the Basketball Hall of Fame in 2012. In 1996, in coordination with the NBA's 50th Anniversary, he was named one of their Top 10 Coaches. In 2021, in coordination with the NBA's 75th Anniversary, he was named one of their Top 15 Coaches.
He married twice, and had 7 children and 15 grandchildren. His son, Donn Charles Nelson, known as Donnie Nelson, played basketball at Wheaton College in Wheaton, Illinois -- making it up to a school that his father had turned down to go to Iowa. Donnie became an assistant to his father the 1st time around with the Warriors, and with the Mavericks, and in between to Dannie Ainge with the Phoenix Suns. From 2005 to 2021, he was the Mavs' GM, helping to build teams that won 3 Division titles, 2 Western Conference titles, and the 2011 NBA Championship.
In 2012, 50 years after leaving the University of Iowa, Don Nelson finally completed his degree there. He settled on a farm on the Hawaiian Island of Maui, where he grew flowers, coffee and cannabis. He hosted poker games, where he was joined by celebrities like country singer Willie Nelson and actor Woody Harrelson, who are also fond of the last of those crops.
"I know how far I've come from being a hog farmer," Nelson said. "I've come a long, long way from being some country kid. I got in the fast lane, and I've stayed there a long time. I've done pretty well."
But his health began to fail, and earlier this year, he moved back to the mainland, to the Dallas suburb of Frisco, Texas. He suffered a stroke, was admitted to hospice care, and died today, August 9, 2026, at the age of 86.
