Milwaukee Bucks (1976–1988) After his career ended, Nelson's son Donnie remembers the family sitting in a Maid Rite restaurant in
Moline, Illinois, 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. A year later he became General Manager of the Bucks and soon began to show what would later become his signature style of wheeling and dealing players. Nelson made his first trade in 1977 by sending
Swen Nater to the
Buffalo Braves and turned the draft pick he received into
Marques Johnson, who had a solid career with the Bucks. On November 25, 1977, the day after Thanksgiving, Nelson managed the greatest fourth-quarter comeback in NBA history. With Milwaukee down twenty-nine points to Atlanta, on the road, and with only 8:43 remaining, the Bucks went on a 35–4 run to win 117–115 in regulation. At the time, there was no three-point field goal. In 1980, he sent off an underachieving
Kent Benson to the
Detroit Pistons for
Bob Lanier. Perhaps his most publicized deal came before the 1984–85 season when he dealt Johnson,
Junior Bridgeman,
Harvey Catchings, and cash to the
San Diego Clippers for
Terry Cummings,
Craig Hodges, and
Ricky Pierce. And, in 1986, he would deal
Alton Lister to the
Seattle SuperSonics for
Jack Sikma. Taking over a Bucks team in the aftermath of
Kareem Abdul-Jabbar's departure to Los Angeles, Nelson was able to improve their win total by 14 games in his first full season as head coach, and established the team as a legitimate championship contender by 1980. It was in Milwaukee where Nelson became known for his unorthodox, innovative basketball philosophy. He pioneered the concept of the
point forward – a tactic wherein small forwards are used to direct the offense. In Nelson's tenure with the Bucks, he used 6–5
small forward Paul Pressey for the role. This enabled Nelson to field shooting guards
Sidney Moncrief and
Craig Hodges or
Ricky Pierce at the same time without worrying about who would run the offense. In his offensive half-court sets, he would also put a center who wasn't a threat on offense, like Lister or
Randy Breuer, at mid-court instead of near the basket to keep a shot-blocking center like the
Utah Jazz's
Mark Eaton away from the basket to make him less of a threat on defense. This system, known as "
Nellie Ball", created a lot of mismatches and enabled Nelson to lead the Bucks to seven straight Central Division championships with over 50 wins in each of those seasons. He earned
NBA Coach of the Year honors in 1983 and 1985. For seven straight years, finishing no worse than second best in the Eastern Conference, the Bucks ended up being eliminated in the playoffs by either the
Larry Bird-led
Boston Celtics or the
Julius Erving-led
Philadelphia 76ers. After the 1986–87 season, which included some controversy and distraction before Game 4 of the 1987 Eastern Conference Semifinals against the Boston Celtics where Nelson told the local sports media that he didn't expect to be back once the season concluded due to a rift with Bucks owner
Herb Kohl, Nelson resigned as head coach of the Bucks. In 11 seasons, Nelson had a 540–344 (.611) record with Milwaukee.
Golden State Warriors (1988–1995) In 1986 former Bucks owner, Jim Fitzgerald, purchased the Golden State Warriors. Nelson did part-time work as a color analyst for NBA games on
TBS during the 1987–88 season. During the season he was contacted by the
Dallas Mavericks,
Golden State Warriors, and
New York Knicks with offers to coach their teams. Nelson decided to go with Golden State, in large part due to his relationship with Fitzgerald, at first buying a minority stake in the team before being named head coach and vice president after one season away from the NBA. In Golden State, he instilled a "
run-and-gun" style of offense. Again using an unconventional lineup which featured three guards (
Mitch Richmond,
Tim Hardaway and
Sarunas Marciulionis) and two forwards (
Chris Mullin and the 6'8"
Rod Higgins at
center), he coached the Warriors to a 23-game turnaround of their previous season and back into the playoffs with his lineup popularly known as
Run TMC, for Tim, Mitch and Chris. All three were later elected to the
Naismith Memorial Basketball Hall of Fame after their careers. Nelson was named NBA Coach of the Year a third time after the 1991–92 season. Nelson continued to retool the team, drafting All-Star
Latrell Sprewell in 1992. Nelson traded the Warriors' number 3 pick
Penny Hardaway to the
Orlando Magic for their number one overall pick
Chris Webber during the
1993 NBA draft. Despite Webber averaging 17.5 points and 9.1 rebounds per game and winning the 1994
NBA Rookie of the Year Award, he found himself at odds with Nelson's preference to play him at center rather than
power forward. Frequently clashing with one another, Webber threatened to use the out-clause in his contract if he wasn't traded. Nelson reportedly offered to resign rather than let the team trade away their young star, but nonetheless Webber was dealt to the
Washington Bullets on November 7, 1994, for
Tom Gugliotta and three future 1st round draft picks (1996, 1998 and 2000). Nelson resigned as head coach of the Warriors on February 13, 1995. He made the playoffs with Golden State in four of his six seasons there. Subsequently, the Warriors did not qualify for the playoffs for the next 12 seasons, until he returned to the team in 2006. The team was marketed as "
Dream Team II". Coached by Nelson, along with assistants
Don Chaney,
Pete Gillen, and
Rick Majerus, Team USA had a roster of
Derrick Coleman,
Joe Dumars,
Tim Hardaway (injured),
Kevin Johnson,
Larry Johnson,
Shawn Kemp,
Dan Majerle,
Reggie Miller,
Alonzo Mourning,
Shaquille O'Neal,
Mark Price,
Steve Smith,
Isiah Thomas (injured), and
Dominique Wilkins. USA went 8–0, defeating Spain 115–100, China 132–77, and Brazil 105–82. In the final round, the U.S. team defeated Australia 130–74, Puerto Rico 134–83, Russia 111–94, and Greece 97–58. In the gold medal game, Team USA defeated Russia 137–91.
New York Knicks (1995–1996) Nelson was hired by the
New York Knicks after their original choice,
Chuck Daly, declined their coaching offer. In 1995, Nelson began his stint with the Knicks, which lasted from July 1995 until March 1996. Nelson coached the Knicks to a respectable 34–25 record, but his up-tempo style of offense sharply contrasted the Knicks' defensive style of play. On March 8, 1996, Nelson was fired as head coach by the Knicks. He was replaced by his assistant,
Jeff Van Gundy. He had a 34–25 record. New York finished 13–10 with Van Gundy, for an overall record of 47–35. Nash won consecutive
MVPs with the Suns the following two seasons. On March 19, 2005, Nelson stepped down as Dallas' head coach, naming
Avery Johnson as his successor. Nelson retained his job as Dallas' GM until after the season, when he named his son, assistant GM
Donnie Nelson, as his replacement as GM. The Mavericks reached the
NBA Finals the following season, though they would lose to the
Miami Heat in six games. Nelson has spoken fondly of his time in Dallas, but admitted he lost interest in remaining with the team when they did not re-sign Nash. In eight seasons with Dallas, Nelson had a 339–251 (.575) record. and Ellis was named the
NBA's Most Improved Player after averaging 16.5 points per game, a substantial increase from his average of 6.8 points per game the prior season. The Warriors closed out the season on a 16–5 run and just managed to qualify for the
2007 playoffs. Nelson faced his former team, the Dallas Mavericks, in the first round of the playoffs. The Mavs had the NBA's best record, and were a pick to win the NBA championship that year. In one of the biggest upsets in NBA playoff history, Nelson coached the 8th-seeded Warriors to series victory over the top-seeded Mavericks in six games. It was numerically the largest upset in the history of the NBA playoffs, with the 67–15 Mavericks' regular-season win–loss record 25 games better than the 42–40 Warriors'. The Warriors went on to lose to the
Utah Jazz in the second round. Nelson became the only coach in NBA history to steer three teams to a first round series victory while being seeded either 7th or 8th, having previously coached the Warriors to first-round upsets of the Jazz in and the Spurs in as the 7th seed. On January 29, 2008,
Chris Webber signed with the Warriors, reuniting with Nelson and returning to the team that had drafted him 15 years earlier. His return lasted only nine games as he was forced to retire due to injuries, but his return signaled closure to arguably the biggest blemish on Nelson's otherwise impressive resume as a player's coach. The Warriors finished 48–34 that season, their most wins since 1993–94 (during Nelson's first stint with the team). However, in a tightly contested Western Conference, the Warriors missed the playoffs by two games. The next two seasons saw the Warriors plunge back into mediocrity (29–53 and 26–56), losing most of the players from their 2007 playoff run to either trades or
free agency. The first of his two losing seasons brought the Warriors the seventh overall pick in the
2009 NBA draft, and Nelson pushed the team to draft
Stephen Curry, despite skepticism from critics. Curry would go on to win back-to-back MVP awards and helped lead Golden State to championships in 2015, 2017, 2018, and 2022. Curry was also named 2022 NBA Finals MVP. On September 23, 2010, Nelson announced he would resign as head coach. The
San Francisco Chronicle reported that new owners
Joe Lacob and
Peter Guber wanted "a young, up-and-coming coach" to help revive the Warriors' fortunes. Longtime assistant
Keith Smart succeeded Nelson as coach. In February 2011, Nelson said on
Bay Area radio station
KNBR that he was fired: "I talked to (Lacob) on the phone before I got fired, and I was really impressed. I was a little surprised with the way things happened, but I think it is for the best for everybody." In 11 total seasons with Golden State, Nelson's teams finished . He ended his coaching career with 2398 games and a 1335–1063 (.557) record. ==Personal life==
