Bob Weiss
NBA Head Coach with Four Franchises | Longtime Mavericks, SuperSonics and Nuggets Assistant
Bob Weiss was born May 7, 1942, in Easton, Pennsylvania, and followed an unusually long NBA playing career with decades of work on professional benches. A guard who won a championship with the 1967 Philadelphia 76ers, Weiss played for several franchises before retiring in 1977. After a short period away from basketball, he joined the San Diego Clippers as an assistant, then became part of the Dallas Mavericks’ original coaching staff during the franchise’s early growth years. His later career would alternate between head-coaching opportunities and extended assistant roles.
Weiss earned his first NBA head-coaching job with the San Antonio Spurs in 1986. Two difficult seasons produced a 59–105 record, though San Antonio reached the 1988 playoffs. After helping the expansion Orlando Magic as an assistant, he took over Atlanta, recording two 43-win seasons across three years, before one season with the Los Angeles Clippers. His fourth and final NBA head-coaching stop was Seattle, where he succeeded Nate McMillan early in 2005–06 and departed after 30 games. Across the Spurs, Hawks, Clippers and Sonics, Weiss finished 223–299.
The bulk of Weiss’s NBA work, however, occurred as an assistant: six seasons with Dallas, a decade in Seattle under George Karl and Nate McMillan, and later positions with Charlotte and Denver. Those appointments put him alongside players ranging from Mark Aguirre and Rolando Blackman to Gary Payton, Shawn Kemp and, late in his career, Nikola Jokić. His history illustrates a crucial truth about NBA coaching: assistants can shape organizations for decades even when their head-coaching stops are measured in just a few seasons.
Overall NBA regular-season head-coaching record: 223–299 NBA. NBA and ABA coaching totals are separated; assistant-coaching assignments carry no head-coaching win–loss credit.
Coaching Career
Weiss began his documented NBA assistant-coaching service with the San Diego Clippers.
Weiss’s first established NBA assistant assignment followed his retirement as a player. With the Clippers in San Diego, he learned the behind-the-scenes work of scouting opponents, developing players and supporting a head coach rather than directing the game himself. These early seasons built the experience he later carried to the expansion Mavericks.
Notable Players Coached
Weiss spent six seasons on the developing Dallas staff, working during the franchise’s early years and its first postseason qualification.
Weiss served as a Dallas assistant during the franchise’s formative 1980s period. The Mavericks progressed from an expansion club into a playoff participant, with Mark Aguirre and Rolando Blackman providing the primary scoring foundation. Those six seasons gave Weiss experience in long-term roster development before he received his first head-coaching offer in San Antonio.
Notable Players Coached
Weiss went 28–54 in 1986–87 and 31–51 in 1987–88. His two-year Spurs head-coaching record was 59–105.
Weiss’s Spurs went 28–54 in 1986–87 and 31–51 in 1987–88. The latter team reached the playoffs but was swept in the first round. His 59–105 two-season record reflects a rebuilding roster that had not yet welcomed David Robinson, whose NBA debut would come in 1989. San Antonio replaced Weiss after the 1988 season.
Notable Players Coached
Weiss joined Orlando during the expansion franchise’s inaugural season.
Weiss spent the Magic’s inaugural 1989–90 NBA season as an assistant, helping establish routines for a completely new organization. His task was not to direct an established contender but to help a young roster adjust to league travel, scouting and daily competition. The appointment separated his Spurs head-coaching job from his later Atlanta years.
Notable Players Coached
Over three seasons in Atlanta, Weiss won 124 of 246 regular-season games, leading the Hawks to playoff appearances in 1991 and 1993.
Atlanta hired Weiss in 1990 and posted 43–39, 38–44 and 43–39 records across his three seasons. Dominique Wilkins and Kevin Willis were major figures, and the Hawks reached the playoffs in 1991 and 1993. Weiss could keep the team competitive but did not produce a deep postseason run, and Atlanta changed coaches in 1993.
Notable Players Coached
Weiss went 27–55 in one season with the Clippers before returning to assistant coaching.
The 1993–94 Clippers finished 27–55 under Weiss after the franchise had reached the playoffs in the preceding two seasons. His assignment lasted only that campaign. Though the record was poor, the stop is important to the correct chronology: it followed Atlanta and preceded a long return to assistant coaching in Seattle.
Notable Players Coached
Weiss served ten seasons on Seattle’s staff, including the 1996 NBA Finals run, before a brief promotion.
Weiss worked on Seattle’s bench from the mid-1990s into 2005, including the Gary Payton–Shawn Kemp era and the later Ray Allen and Rashard Lewis period. He served under coaches with different approaches and helped sustain continuity across roster and ownership changes. This assistant tenure was substantially longer than any one of his NBA head-coaching appointments.
Notable Players Coached
Weiss coached 30 games of the 2005–06 season, going 13–17 before Bob Hill succeeded him.
Promoted to Seattle head coach for 2005–06, Weiss went 13–17 over the club’s first 30 games before Bob Hill replaced him. The episode was a brief return to the lead chair after more than a decade as a Sonics assistant. His final NBA head-coaching record across four organizations was 223–299.
Notable Players Coached
Weiss joined Charlotte’s staff for several seasons, a notably late-career NBA appointment.
Weiss returned to an NBA bench as an assistant with Charlotte beginning in 2013–14, helping coaches and players prepare during the team’s transition back to the Hornets name. The appointment reflected his continued value as a veteran teacher rather than a return to head coaching. The Charlotte period is listed separately from his earlier clubs to preserve chronology.
Notable Players Coached
Denver was Weiss’s last listed NBA assistant assignment, overlapping a 2017–18 Charlotte coaching entry in historical staff records.
Weiss served on Denver’s staff in the late 2010s, overlapping the early emergence of Nikola Jokić as an offensive hub. His assistant role came decades after he began in San Diego and Dallas. It illustrates how his coaching experience carried into a modern league built around different spacing and skill profiles.
