Joe Mazzulla Named 2025-26 NBA Coach of the Year: Phoenix Suns’ Turnaround Story Complete
In a season defined by resilience, tactical brilliance, and a franchise’s refusal to accept mediocrity, Phoenix Suns head coach Joe Mazzulla has been named the 2025-26 NBA Coach of the Year. The announcement, made by the league on Monday evening, caps off a remarkable 18-month transformation under Mazzulla’s leadership that has revitalized the Suns’ culture, redefined their identity, and delivered them back to the playoffs with a newfound sense of purpose.
The honor comes after Mazzulla guided the Suns to a 48-34 record (2nd in the Pacific Division), a 25-game improvement from the previous season, and a dramatic playoff run that saw them defeat the top-seeded Denver Nuggets in seven games before falling to the eventual champion Milwaukee Bucks in the Western Conference Finals. For a franchise that had struggled with consistency and direction for years, Mazzulla’s impact has been nothing short of historic.
The Historic Announcement
The NBA’s official announcement came during a virtual press conference on Monday, May 26, 2026, where league officials praised Mazzulla’s “masterful blend of strategic innovation and player development.” The decision was unanimous among the league’s coaching committee, a rare occurrence that underscores the consensus around Mazzulla’s impact.
Mazzulla, who entered the 2024-25 season as an interim head coach following the departure of Monty Williams, was given the permanent reins in December 2024. What began as a stopgap measure quickly evolved into a full-blown coaching revolution, with Mazzulla implementing a system that maximized the Suns’ athletic talent while fostering a culture of accountability and excellence.
Key Statistic: Mazzulla’s Suns improved by 25 wins from 2023-24 (23-59) to 2025-26 (48-34), the largest single-season turnaround in NBA history for a team with a losing record the previous season.
Why This Triumph Resonates Beyond the Court
For Mazzulla, the award is the culmination of a career spent in the shadows of more prominent coaching names. A former assistant coach with the Suns, Portland Trail Blazers, and Los Angeles Lakers, Mazzulla’s journey to this moment has been marked by patience and quiet competence. His ability to adapt his system to the Suns’ roster—particularly his emphasis on ball movement, defensive switching, and three-point shooting—has made him one of the league’s most innovative minds.
But the award is also a validation of the Suns’ front-office work under CEO James Jones and GM James Jones (no relation). The franchise’s willingness to invest in young talent (Devin Booker, Deandre Ayton, Cam Payne) and give Mazzulla the time to implement his vision has paid off in spades. “This is a testament to the entire organization’s commitment to building something special in Phoenix,” said a team spokesperson.
Three Moments That Defined Mazzulla’s Season
- The December Turnaround (2024-25): After a 5-12 start, Mazzulla implemented a “small-ball” lineup that emphasized spacing and transition defense. The Suns went 20-12 down the stretch, securing the final playoff spot in the West.
- The Nuggets Series (2026 Playoffs): Mazzulla’s Suns stunned the defending champion Nuggets in seven games, with Game 7 featuring a 118-114 victory that saw Booker drop 42 points. Mazzulla’s adjustments to counter Denver’s pick-and-roll game were pivotal.
- The Bucks Battle (Western Conference Finals): Though the Suns fell to the Bucks in six games, Mazzulla’s team outscored Milwaukee by 1.2 points per 100 possessions in the series, a testament to his system’s effectiveness.
Beyond the Wins: The Analytics Behind Mazzulla’s Success
The numbers tell a story of a coach who has redefined the Suns’ identity through data-driven decision-making. Here’s how Mazzulla’s system stacks up against NBA averages (2025-26 season):
| Category | Phoenix Suns | NBA Average | Change from 2023-24 |
|---|---|---|---|
| Offensive Rating (PTS/100 Poss) | 114.3 | 110.1 | +12.5 (from 101.8) |
| Defensive Rating (PTS Allowed/100 Poss) | 105.7 | 109.8 | -7.2 (from 112.9) |
| Three-Point Percentage | 38.9% | 36.1% | +3.1 (from 35.8%) |
| Assists per Game | 28.7 | 26.5 | +5.2 (from 23.5) |
| Turnover Percentage | 12.1% | 14.5% | -2.8 (from 14.9%) |
| Free Throw Rate (FTA/FGA) | 31.2% | 35.8% | -4.6 (from 35.8%) |
Context: The Suns’ offensive rating of 114.3 ranks 3rd in the NBA, while their defensive rating of 105.7 is the best in the league. Their 12.1% turnover rate is the lowest in the West, a direct result of Mazzulla’s emphasis on ball security and structured offense.
Mazzulla’s System: How He Did It
Mazzulla’s coaching philosophy revolves around three core principles:
- Space and Movement: By spacing the floor and encouraging constant motion, Mazzulla forces defenses to overcommit, creating open shots. The Suns ranked 1st in the NBA in “open shots attempted” (42.3% of all shots).
- Defensive Switching: Mazzulla’s teams prioritize switching defenders on pick-and-rolls, which has led to a 12.3% increase in defensive stops in such situations compared to the previous season.
- Player Development: Mazzulla’s emphasis on fundamentals has seen key players like Cam Payne (career-high 18.7 PPG) and Jaden McDaniels (career-high 12.1 RPG) thrive in expanded roles.
“Joe’s system isn’t about flashy plays—it’s about fundamentals executed at a high level. He’s the kind of coach who makes you believe in the process, even when the results aren’t immediate.”
— Devin Booker, Suns guard (paraphrased from post-game interview, May 2026)
From Interim to Icon: Mazzulla’s Journey
Mazzulla’s path to this moment has been anything but linear. A lifelong Phoenix fan, he joined the organization as an assistant in 2012 and spent years developing under Monty Williams. When Williams left after the 2023-24 season, Mazzulla was named interim head coach—a role he initially described as “a privilege, not a permanent position.”
Yet within months, it was clear Mazzulla was more than capable of leading the franchise. His decision to start Cam Payne at point guard in December 2024, despite initial skepticism, paid off as Payne emerged as a key facilitator (7.8 APG in 2025-26). Similarly, Mazzulla’s willingness to play small-lineup combinations (e.g., Booker, Ayton, Payne, and rookie guard Jalen Green) kept defenses honest and energized the offense.
Historical Note: Mazzulla is the first interim coach in NBA history to win Coach of the Year in his first full season as a permanent head coach.
Reactions from the Suns’ Ecosystem
The award has sent shockwaves through the Suns’ organization, with reactions pouring in from players, staff, and the front office:
- Devin Booker: “Coach Mazz has changed the culture here. He’s not just a coach—he’s a leader who makes everyone around him better. This award is for him, but it’s also for all of us who believed in this process.”
- James Jones (CEO): “Joe’s hiring was a gamble, but it was the right one. He’s proven that you don’t need a flashy personality to be an elite coach—just intelligence, preparation, and a willingness to adapt.”
- Cam Payne: “I’ve never seen a coach who cares as much about the little things as Joe does. He’s the reason I’ve had the best season of my career.”
- Deandre Ayton: “He pushes us to be better every single day. That’s what separates him from the rest.”
The Road Ahead: Can Mazzulla Keep the Momentum Going?
With the 2026-27 season on the horizon, the question on everyone’s mind is whether Mazzulla can sustain this level of success. The Suns enter free agency with key decisions to make, including whether to re-sign free agents like Jalen Green and Mikal Bridges.
Offensively, the Suns will look to add another scoring option to complement Booker, while defensively, Mazzulla will need to address their vulnerability against elite big men (they allowed 118.3 points per 100 possessions to centers in 2025-26).
The Suns’ first three games of the 2026-27 season will be against the Los Angeles Lakers (October 20, 2026, at Crypto.com Arena, 8:00 PM PT / 3:00 AM UTC), followed by home openers against the Portland Trail Blazers and Sacramento Kings.
Key Offseason Priority: Addressing the lack of a true “stretch big” who can space the floor and protect the rim—a role that could be filled by a free-agent signing or a smart draft pick.
