Star players undoubtedly drive the narrative of the NBA, yet it is essential to highlight those who make significant contributions to their teams without the same level of recognition. This task of ranking the most underrated players in the league over the past five years is subjective and inherently inexact. The aim is to acknowledge consistent contributors who lack typical star credentials but significantly impact their respective teams.

Royce O'Neale remains in the fifth spot in the rankings, reflecting his continued worth and performance since last year. Though some may argue that consecutive appearances in the 'Most Underrated' category diminish the notion of being underrated, O'Neale's contributions cannot be overlooked. This 32-year-old player has emerged as a standout among low-usage wings, efficiently shooting from three-point range while also dedicating himself to defensive efforts. Since the 2020-21 season, O'Neale has made 724 three-pointers at a commendable 38.8 percent success rate. His extraordinarily low usage rate, just above 12 percent, is the lowest among players who have achieved such volume and efficiency, underscoring the significance of his contributions that often go unrecognized.

Isaiah Hartenstein's advancements led him out of the rankings when he signed a three-year, $87 million contract with the Oklahoma City Thunder. However, this context is frequently overlooked. His contract effectively reflects a two-year commitment, as the team has a team option on its final season. Hartenstein stands out as one of the most well-rounded big men in the league, with abilities that encompass setting screens, excellent rebounding, shot-blocking, and playmaking. Notably, he ranks tenth in Value Over Replacement Player (VORP) among players averaging at least 20 minutes per game without earning an All-Star selection, illustrating the substantial impact he has had on the court.

Josh Hart often faces criticism for his shooting inefficiencies, particularly his low-percentage three-point shot. While his detractors have valid points, Hart's relentless hustle contributes to team success. Despite a challenging past season with the New York Knicks, where his on-off statistics did not reflect his true impact, Hart continues to embody essential elements of team identity through his aggressive rebounds, fast-paced offensive contributions, and defensive versatility. His 58.7 true shooting percentage remains significantly above league average, and he is among a select group of players, including Bam Adebayo, Luka Dončić, and Nikola Jokić, boasting similar statistical achievements.

Derrick White's inclusion at number two on this list may raise eyebrows, especially considering he has garnered attention for possible All-NBA nominations in recent years. However, despite the buzz, White has yet to claim an official All-NBA or All-Star selection, underscoring that he still does not receive recognition befitting his contributions. His defensive prowess has been a hallmark of his game, and he has recently elevated his offensive skills, showcasing improved decision-making, three-point shooting, and playmaking abilities. It is notable that he leads all non-All-Stars in VORP since the 2020-21 season, further solidifying his case as one of the most underrated players in the league.

Ivica Zubac captured the attention of many with his recent breakout season, earning consideration for both Most Improved Player and Defensive Player of the Year. Although this past year's performance was particularly noteworthy, Zubac's consistent development has been gradual and significant over the last five years. His advancements in defensive skills, rebounding techniques, and offensive strategies have culminated in a season where his stats reflect his achievements fully. Zubac has consistently ranked in the top percentile for rim points saved per 100 possessions, maintaining a robust performance over multiple seasons. This sustained excellence places him among a select group of players who have achieved remarkable consistency during this timeframe.
