NBA coaching trees are where a lot of power hides. NBA coaching trees explain why ideas from Boston in the 1960s show up in Golden State in the 2010s, or why a sabbatical year at Kansas quietly links San Antonio and Detroit. This list looks at 14 NBA coaching trees that connect champions across very different franchises. Some branches are obvious. Some are subtle. All of them show how rings and ideas travel from bench to bench over time.
Context
Titles rarely belong to one person. They belong to habits that move from room to room. A coach wins with one team, an assistant leaves, and suddenly a different franchise is running the same shell drill or late game set in another city.
Coaching trees matter because they show how ideas travel. Red Auerbach was built in Boston, but his players shaped later teams across the league. Pat Riley turned heat and pressure into a standard in Los Angeles, New York and Miami, then handed a clipboard to Erik Spoelstra. Gregg Popovich turned the Spurs into a teaching lab that produced head coaches and systems all over the map.
When you follow the branches, you start to see that multiple champions share the same roots even when the uniforms and owners could not be more different.
Methodology: Data sources include official league records, Hall of Fame bios, team media guides, coaching clinics and long form reporting, weighted by combined championships, number of head coach branches, franchise variety and long term influence, with ties settled by overall impact rather than trophy count.
Coaching Trees Across Franchises
1. Red Auerbach to Don Nelson
The defining image is simple. Red Auerbach sits back on the Boston bench with a cigar ready while young forward Don Nelson runs the floor next to Bill Russell and John Havlicek. Auerbach won 9 titles as head coach and helped create a run of 8 straight championships that still stands as the standard for dominance.
Why it matters: Those Celtics teams linked future coaches and executives. Nelson carried ideas from that locker room into his own long coaching career, where he piled up more than 1,300 regular season wins with Milwaukee, Golden State, New York and Dallas. The tree connects Celtic hardware to later Mavericks success under Rick Carlisle, who played for and worked with Nelson before leading Dallas to a title.
2. Pat Riley bench to front office
Picture Pat Riley in a suit on the Lakers sideline during the Showtime years. Then picture him later in Miami, sleeves rolled, leading a very different group. Riley won 4 championships as Lakers head coach and a fifth with the Heat, then added more rings as an executive in Miami.
Why it matters: His coaching tree runs through multiple franchises. Assistants Stan Van Gundy and Jeff Van Gundy carried defensive principles to Miami, Orlando and New York. Erik Spoelstra came from Riley’s own staff and led Miami to titles with LeBron James, then to more Finals trips with very different rosters. Riley is known for a simple standard. No rebounds, no rings.
3. Phil Jackson triangle to Kerr
Phil Jackson’s defining moments involve huddles with Michael Jordan and Scottie Pippen in Chicago, then Kobe Bryant and Shaquille ONeal in Los Angeles. Jackson won 11 titles as a head coach, more than any other, with Bulls and Lakers groups that defined entire eras.
Why it matters: His coaching tree is less about assistants winning titles and more about players and staff who carried his ideas. Steve Kerr played for Jackson in Chicago, absorbed the triangle’s spacing and trust rules, then later applied parts of that mindset to the Warriors motion system in Golden State, where he won multiple championships as head coach.
4. Gregg Popovich global coaching tree
The defining moment for this tree might be Popovich standing beside Tim Duncan as the Spurs close another Finals series, then later greeting Steve Kerr and Ime Udoka as rival head coaches who once worked with him. Popovich won 5 titles with San Antonio and became the league’s leader in career coaching wins.
Why it matters: Popovich’s coaching tree stretches everywhere. His former assistants include Mike Budenholzer, who won a title with Milwaukee, and Mike Brown, now leading Sacramento after time with Cleveland and Golden State. Steve Kerr played for Popovich, then became a championship coach in Golden State. Ime Udoka, Taylor Jenkins and Will Hardy also came through the Spurs pipeline before getting their own benches.
5. Larry Brown Kansas to Pistons
The key snapshot comes from the mid 1980s, when Larry Brown’s staff at Kansas included Gregg Popovich, Alvin Gentry, future Kansas legend Bill Self and future Spurs executive RC Buford all in the same program.
Why it matters: Brown later won an NBA title with the Pistons and an NCAA title at Kansas. His idea of playing the right way shaped both pros and college winners. Brown himself often said he just asked players to play the right way, defend, rebound, share the ball and give great effort. From that Kansas locker room, Popovich went on to build Spurs championships, while Self turned Kansas into a long running college powerhouse.
6. Don Nelson pace and space legacy
Don Nelson’s defining pro moment came later than his Celtic playing days. Think of his creative Warriors and Mavericks teams flying up the floor and taking early threes while other teams still pounded the ball inside. Nelson never won a title as a head coach, but he finished with more than 1,300 coaching wins and pushed the league toward faster, more perimeter heavy offense.
Why it matters: Nelson played for Auerbach and brought that freedom into modern systems. His influence reaches Rick Carlisle, who worked with him in Dallas before taking the Mavericks to a championship, and Mike D’Antoni, whose Phoenix teams adopted similar ideas about spacing and tempo.
7. Chuck Daly physical defense school
Picture the Detroit Pistons celebrating in 1989 and 1990 with Chuck Daly standing quietly off to the side as the Bad Boys enjoy the moment. Those teams won back to back titles by leaning into physical defense, detailed game plans and a deep understanding of roles.
Why it matters: Daly’s tree includes assistants and rivals who borrowed his ideas. Brendan Malone later passed that defensive mindset on to his son Michael Malone, who led Denver to a title of his own. Other coaches used Daly’s example to justify building defensive identity first, even in star driven eras.
8. Jerry Sloan Jazz stability line
Jerry Sloan’s defining moment is less a single game and more a stretch of years. From the late 1980s through the 2000s he guided the Utah Jazz, reaching multiple Finals with Karl Malone and John Stockton and posting more than 1,100 wins as head coach.
Why it matters: Sloan did not win a ring as a head coach, but his tree lives through continuity and through sets that spread across the league. His flex based offense, with constant backscreens and cuts, and his ball screen patterns turned into templates that later contenders copied and folded into their own playbooks. Coaches on title teams in San Antonio and elsewhere have acknowledged using similar actions to free shooters and bigs.
9. Van Gundy defensive teaching strand
The defining image here is Jeff Van Gundy hanging on to Alonzo Mourning’s leg during a scuffle, a clip that still floats around whenever fans talk about intense coaches. Jeff and Stan Van Gundy became known for disciplined defenses in New York, Houston, Miami and Orlando.
Why it matters: Their tree branches into later coaches who came through their staffs or adopted their philosophies. Tom Thibodeau worked with Jeff and helped build elite defenses in Boston as an assistant, then in Chicago and later New York as a head coach. Those Celtics teams won a title with defense as their backbone, and the Bulls became regular top tier defenses under his watch.
10. Mike D’Antoni spread pick and roll
Think of D’Antoni’s Phoenix Suns, with Steve Nash walking the ball up, then suddenly playing in early drag screens while shooters space the corners. Those teams never won a ring, but they changed how the league used pick and roll and three point shooting.
Why it matters: DAntoni’s tree includes assistants and players who brought that spread style to other contenders. Nash later worked with Golden State, while former staffers and players helped carry similar spacing ideas to Houston and Brooklyn. The link back to Nelson is clear, but the branch is distinct because of how central the ball screen became.
11. Doc Rivers player centered voice
Doc Rivers had his defining coaching moment in 2008 when Boston lifted a trophy after a season built on defense, sacrifice and clear roles for the Big Three. That title pushed him into the conversation with other elite coaches of his era.
Why it matters: Rivers’ tree touches several franchises. Assistants and former players carried his emphasis on communication to future roles in Los Angeles, Philadelphia and Milwaukee. His title in Boston and long run with the Clippers helped normalize the idea that star groups needed a coach who could manage egos as much as schemes.
12. Steve Kerr modern motion tree
One of Kerr’s key moments came in 2014 when he took the Warriors job and decided not to stick with a pure isolation style, even with Stephen Curry and Klay Thompson already in place. Instead he blended motion concepts from his time with Popovich and Jackson, plus ideas from DAntoni era offense.
Why it matters: Kerr’s Warriors won multiple titles and changed league expectations about ball and player movement. Assistants like Mike Brown took those lessons to Sacramento, where the Kings built one of the highest scoring offenses in recent seasons. Other staffers brought pieces of the system to Phoenix and other stops.
13. Erik Spoelstra video room path
The defining image for this tree does not come from the court. It comes from an old Miami Heat video room, where Spoelstra first worked cutting film for Riley before rising all the way to the head coaching job. He then led Miami to multiple titles with LeBron James and more Finals runs later with very different rosters.
Why it matters: Spoelstra’s path gave hope to younger staffers around the league. Assistants and former players from his teams have moved into coaching roles elsewhere, taking with them an emphasis on preparation, versatility and zone usage that has influenced playoff series in both conferences.
14. College bluebloods into NBA benches
The final tree is more of a web. Picture Kansas and North Carolina legends on one board. Names like Phog Allen, Larry Brown, Roy Williams and Bill Self at Kansas, and Dean Smith and Roy Williams again at North
Carolina, feeding players and future coaches into the NBA for decades.
Why it matters: This college to pro tree connects several NBA champions. Smith coached Michael Jordan at North Carolina before Jordan joined Jackson in Chicago. Brown mentored Popovich and Self at Kansas before his NBA title in Detroit. Self then coached future NBA stars who landed under various pro coaching trees.
What Comes Next
Coaching trees never stop growing. Assistants on Popovich or Kerr staff get their own teams. Video coordinators under Spoelstra move up a row on the bench. College coaches mentored by Brown or Self keep sending players and young staffers into the league.
NBA coaching trees that link multiple champions across different franchises will only get more tangled as time passes. The next great idea might already be sitting two seats down from a veteran coach on a quiet regular season night, waiting for a chance.
Which assistant on a current contender will be the next name we add to this list of coaching trees that link banners in very different buildings?
