Mark Daigneault’s top spot is a testament to the Thunder’s recent postseason success under his leadership. Since taking over as head coach in 2020, Daigneault has transformed the Thunder into a formidable force, blending a young, talented roster with a fast-paced, disciplined style of play.

His 71.4% playoff winning percentage reflects OKC’s deep runs, including a strong showing in the 2024 playoffs where they pushed past the first round before falling to the Dallas Mavericks in a competitive series. Daigneault’s ability to maximize the potential of players like Shai Gilgeous-Alexander and Chet Holmgren has made the Thunder a perennial playoff contender, and this statistic underscores his impact on the franchise.

The rest of the list features a mix of modern and legendary coaches. Steve Kerr, at 70.6%, has cemented his legacy with the Golden State Warriors, leading them to four NBA titles since 2015. David Blatt’s 70.0% is a surprising inclusion, largely due to his brief but successful stint with the Cleveland Cavaliers in 2015, where he guided LeBron James and company to the NBA Finals. Joe Mazzulla, at 69.8%, represents the new guard, having led the Boston Celtics to a championship in 2024 during his second year as head coach.

Finally, Phil Jackson’s 68.8% rounds out the list, a nod to his unparalleled success with the Chicago Bulls and Los Angeles Lakers, where he won 11 championships across two decades. This ranking not only celebrates Daigneault’s achievements but also highlights the enduring excellence of coaches who have defined the NBA’s playoff landscape.
