Dallas is entering a rebuild phase after a difficult 26-56 season, aiming to shape a young core around Cooper Flagg, Johnson, and other developing talents while the front office pursues a new direction. The prospect of a college-to-NBA transition is intriguing, but it also carries a history of steep learning curves. The locker room dynamics, travel schedule, and the shift from a collegiate to a professional calendar can present unexpected obstacles. To better understand May’s situation, it’s helpful to examine how the last decade has treated college coaches making the jump to the NBA.
1) John Beilein
Beilein’s jump from Michigan to the NBA is often cited as the cautionary tale. He arrived in Cleveland in 2019 with a reputation for structured offenses and player development. The results were abrupt: a 14-40 start, culminating in Beilein’s resignation before the season ended. The cultural mismatch—his collegiate teaching style clashing with professional players—proved difficult to overcome. May’s challenge is different in key respects: he enters with younger players and a direct line to a potential star in Flagg, plus a staff that may be more receptive to non-traditional approaches. Still, Beilein’s experience serves as a reminder that college success does not automatically translate to NBA durability.
2) Billy Donovan
Donovan’s trajectory offers a more hopeful blueprint. After national titles at Florida, he found NBA footing with the Oklahoma City Thunder, delivering a solid start and conference finals contention in 2016. Donovan later coached the Chicago Bulls, where he showed flashes but did not secure sustained playoff contention. His overall NBA record remained positive, underscoring that a successful college-to-NBA transition is possible when a coach adapts to evolving rosters and roster-building timelines. For May, this suggests patience, adaptability, and the importance of building an organizational culture that fits the Mavericks’ timeline.
3) Fred Hoiberg
Hoiberg’s experience underscores the risks of mismatched fit. Touted for an up-tempo offense rooted in college, he encountered a roster that wasn’t aligned with his vision. The result was a slow, challenging tenure and a shortened tenure in Chicago. The takeaway for May is clear: offensive philosophy must harmonize with the pieces surrounding him, and the NBA demands alignment between coaching philosophy and the talent pool.
4) Brad Stevens
Stevens remains a standout example of a college coach thriving in the NBA, aided by a patient front office and a gradual rebuilding process. He guided the Boston Celtics from a rough start to multiple playoff berths and conference finals appearances, eventually moving into front-office leadership and contributing to a championship team. For May, Stevens represents the high bar: thoughtful development, strategic patience, and a willingness to evolve as a coach and organizer. Dallas’ rebuilding posture around Flagg and Johnson could offer May a similar runway if the organization commits to a coherent long-term plan.
5) Reggie Theus
Theus benefited from NBA credibility as a former player, which helped him secure the Kings job. Yet his NBA coaching tenure was relatively brief and underscored how heightened expectations, roster limitations, and timing can derail even well-regarded college coaches. The example highlights the importance of the supporting cast and roster strategy in the NBA.
6) Mike Montgomery
Montgomery’s college triumphs at Stanford contrasted with a more modest NBA run with the Warriors, where the transition yielded average results. This illustrates that even renowned college tacticians can struggle to replicate success in the NBA’s faster pace and different decision-making environment.
7) Leonard Hamilton
Hamilton’s NBA stint with the Wizards was short and difficult, hampered by a roster lacking sufficient talent and direction. He later found success in college, proving coaching acumen translates differently across levels. For May, this emphasizes the need for a strong, adaptable plan in Dallas that can still honor his strengths while acknowledging personnel realities.
8) Lon Kruger
Kruger demonstrated adaptability across programs and levels, but his NBA tenure with the Hawks was not enduring. The takeaway is that sustained NBA impact requires the right timing, support, and fit, not just a strong college résumé.
9) Tim Floyd
Floyd’s tenure with the Bulls is often cited as one of the most challenging scenarios, arriving after a dynasty era with a roster that needed rebuilding rather than reloading. The experience underscores how a misalignment between the coach’s strengths and the roster’s needs can lead to rapid setbacks.
10) Rick Pitino
Pitino’s high-profile NBA stint with the Celtics ended unsuccessfully, despite a dominant college career and a track record in basketball operations. His case illustrates how big names and strong pedigrees do not guarantee NBA success without a fit between organizational goals and coaching approach.
Is May Destined for Failure?
The history of college-to-NBA pivots makes it clear that success is not guaranteed, even for highly accomplished coaches. The NBA demands a different balance of authority, communication, and flexibility than college programs. May cannot expect automatic respect or instantaneous results based solely on his Michigan accomplishments. The most successful transitions tend to come from a coach who blends a clear, adaptable offensive philosophy with strong player development and a willingness to adjust to the realities of the professional game.
There are reasons for optimism in Dallas. Cooper Flagg represents a promising foundation with significant room for growth, and veteran pieces like Kyrie Irving provide experienced counterbalance as the team navigates its rebuilding phase. The Mavericks are approaching this period with a clear intention to rebuild rather than chase immediate wins, which can be a conducive environment for a coach still early in their career.
Ultimately, May’s success will hinge on his ability to learn quickly, build trust with players, and tailor his approach to the NBA’s realities. If he leans into collaboration with the front office, embraces a measured timeline, and leverages his strengths in player development and scheme design, he could carve out a productive niche in Dallas. If, however, the transition mirrors the Beilein scenario or other early misfits, the challenges could intensify. The path forward lies in adaptability, patience, and a robust, shared vision for how the Mavericks will evolve over the coming seasons.
