Nelson, affectionately known as “Nellie,” was a hugely successful player and coach whose ingenuity helped
shape the game into what it is today.
Player
A 14-year pro, Nelson played his rookie season with the Chicago Zephyrs, then his next two for the Los Angeles Lakers before signing as a free agent with the Boston Celtics. There, he went on to play 11 seasons, winning five NBA Championships. In Game 7 of the 1969 NBA Finals, he famously hit a clutch shot with just over a minute to go to give the Celtics the lead in what would become their 11th title in 13 seasons.
An ironman on the court, Nelson played all 82 games six times across his career, including an unfathomable five times in a row from 1967-68 to 1971-72. In total, he accumulated 10,898 points (10.3 PPG), 5,192 rebounds (4.9 RPG), and 1,526 assists (1.4 APG). He recorded a personal career-high 40 points against the San Diego Rockets in 1970 and posted a career-high 22 rebounds against the Boston Celtics in 1968.
Coach
While a quality player and pivotal member of many championship teams—you don’t get your jersey number retired in Boston if you’re not—Nelson arguably left his biggest mark on the league as a coach. When it comes to Milwaukee, there’s no doubt about it.
Nelson moved to the Bucks as an assistant coach immediately after his playing career finished and, after head coach Larry Costello resigned following a 3-15 start, took over the reins. In his second season at the helm, he led the Bucks back to the playoffs; in his fifth, he took them to 60 wins, third most in the league. It was the beginning of a golden era of basketball in Milwaukee, with the Bucks winning at least 50 games in each of the next six seasons. In that time, the Bucks won seven straight Central Division championships and reached the Eastern Conference Finals three times, losing to the eventual champion Philadelphia 76ers in 1983 and succumbing twice to Nelson’s former Celtics, who would also go on to win the NBA Championship, in 1984 and 1986.
Nelson finished his time in Milwaukee as the longest-tenured and winningest coach in franchise history. With 540 regular season wins (61% win percentage), he sits comfortably ahead of second-place Costello (410 wins, 61%), and has nearly twice as many wins as third-placed Mike Budenholzer (271, 69%). He also owns the most playoff victories as a coach in Bucks history (42, compared with 39 for Budenholzer and 36 for Costello).
Following his tenure in Milwaukee, Nelson went on to coach the Golden State Warriors (on two separate occasions), New York Knicks, and Dallas Mavericks. While unsuccessful in his first stop in Golden State and fired early in his stint in New York, Nelson transformed a floundering Dallas franchise into a legitimate contender—largely on the back of a pair of draft day moves that netted the Mavs Dirk Nowitzki (via the Bucks) and Steve Nash (via the Phoenix Suns)—and later led the 2006-07 “We Believe” Warriors to a historic upset series win against the first-seeded, 67-win Mavericks.
In total, Nelson coached 2,398 games, going 1,335–1,063 (56%), and remains second in NBA history for wins as a coach. For his efforts, he was a three-time recipient of the NBA’s Coach of the Year award (1983, 1985, 1992), and was named to both the Top 10 Coaches in NBA History and the 15 Greatest Coaches in NBA History during the league’s 50th and 75th anniversary celebrations. Nelson was inducted into the Naismith Memorial Hall of Fame as a coach in 2012.
Revolutionary
Beyond his raw success as a coach, Nelson was nothing short of a pioneer. Always looking for a strategic advantage, he was inventive in a number of ways across his coaching stops.
In Milwaukee, this came to fruition through “Nellie Ball” which relied on positional versatility and athleticism. In this system, centres were less pivotal and scoring guards were given the green light through Nelson’s invention of the point forward position, which was made famous by Bucks legends Marques Johnson and Paul Pressey. If this sounds like the forerunner for modern NBA offences, it’s because it was.
In both stints with the Warriors, Nelson leaned into small ball, often employing three-guard lineups, and would frequently forego a centre altogether. Then, with Nowitzki and the Mavs, he helped transform the power forward position into the perimeter-oriented one it has become today—and also brought to prominence the “Hack-a-Shaq” strategy that coaches still utilise to exploit poor free throw shooters (see the San Antonio Spurs’ treatment of Mitchell Robinson in last season’s Finals).
In brief, Nelson’s fingerprints are all over the modern game.
Tributes
Nelson’s passing has reverberated across the NBA landscape, such was his impact. Here’s how some notable figures paid their respects, in their own words:
Nellie… You didn't just draft me. You believed in me. You saw things in my game before I ever realized I could do them. I've said it a million times and I will always say it: I don't think my career could have turned out how it did without you being my first coach and giving me…

RIP, Don. A basketball genius among basketball geniuses. A legend among legends. https://t.co/RmxosU0sHf

What makes his legacy special is that he didn’t just coach — he expanded the way it could be played. His fingerprints on the modern NBA; space/movement/creativity.

It’s times like these that truly remind us all of what’s important. Yes, this beautiful game draws so much of our attention—the wins and the losses and everything in between—but, really, it’s the people who matter. And so whether it’s the person across your desk right now or your loved ones at home, be sure to spend that extra moment with them. Tell them what they mean to you. Laugh, cry, connect. Fill your cup. Like Nellie would.
May he rest in peace.
