Measures how much a coach overperformed or underperformed relative to their roster talent. The best coaches squeeze more wins out of average rosters. This is the CIR formula's primary component (weight: 200). A coach who takes a projected 35-win roster to 50 wins demonstrates enormous coaching impact.
Auerbach consistently exceeded expectations with .662 career win percentage, building the Celtics dynasty from scratch and winning 9 championships in 10 years as coach/executive despite limited free agency options in his era.
Jones had a .674 career win percentage and consistently exceeded expectations with the Celtics, winning 2 championships while maximizing aging stars and integrating new talent seamlessly.
Fitch consistently overperformed expectations, taking expansion Cavaliers from 15 wins to playoffs in 4 years and turning around struggling franchises like Boston and Houston with limited rosters.
Budenholzer consistently exceeded expectations with both Atlanta (60-win season with limited star power) and Milwaukee (transforming them from playoff disappointment to championship team). His .611 career win percentage reflects strong overperformance relative to roster talent.
Snyder consistently overperformed expectations with Utah Jazz rosters, turning them into a perennial playoff team and reaching the conference semifinals multiple times with limited star talent.
Heinsohn's .619 coaching win percentage with two championships exceeded expectations for most of his tenure, particularly given roster limitations in later years.
D'Antoni consistently exceeded expectations with the Suns, turning them into a 60+ win team with Nash and role players. His fast-paced system maximized talent beyond projections.

Nurse consistently exceeded expectations with Toronto, winning 58 games in 2018-19 when many projected mid-50s, and led a team not expected to win the championship to the title. His innovative schemes regularly got more from rosters than talent suggested.
Malone consistently exceeded expectations with Denver, taking them from lottery team to championship contenders and 2023 NBA champions with largely the same core roster.
Van Gundy consistently overperformed with limited offensive talent in New York, making the Finals in 1999 and regularly winning 45-50+ games with defensive-minded rosters that lacked star power.
Carlisle consistently exceeded expectations, particularly with the 2011 Mavericks championship team that wasn't favored and his ability to keep Indiana competitive with limited talent. His .547 career win percentage reflects solid overperformance relative to roster expectations.
Tomjanovich's Rockets consistently exceeded expectations, particularly during the championship runs when they weren't favored. His .559 career win percentage with rosters that weren't always elite talent suggests strong overperformance.
Karl's .599 career win percentage with often limited rosters in Seattle and Denver shows consistent overperformance. His teams regularly exceeded expectations by 3-5 wins, particularly in Denver where he maximized aging stars and role players.
Lue's 2016 Cavaliers exceeded expectations by winning the championship against the 73-win Warriors, and his Clippers have generally performed at or slightly above roster expectations despite injuries.

Wilkens consistently exceeded expectations, particularly with Seattle's 1979 championship team and Cleveland's overachieving 1990s squads. His .564 career win percentage with often limited rosters demonstrates strong overperformance.
Casey consistently exceeded expectations with Toronto, taking them from lottery team to 59 wins and #1 seed in 2018. His .540 career win percentage with limited star talent shows strong overperformance.
Donovan's Thunder teams generally met expectations given their talent level, while his Bulls teams have slightly overperformed modest expectations in recent seasons.
