The NBA is often driven by star talent, yet it is essential to recognize players who may not command the same spotlight but make significant contributions to their teams. Identifying the most underrated players in the league over the past five years is a subjective endeavor; however, it serves to highlight those who have continuously delivered without receiving the accolades typically associated with stardom. To establish a preliminary list, certain criteria have been implemented, and each player mentioned here is deserving of being acknowledged for their efforts during this time frame.

Royce O'Neale retains his fifth place from the previous year, sparking discussions about whether consecutive appearances in the top-five rankings categorize him as 'not underrated.' At 32 years old, O'Neale's age may affect his standing among these players. Nevertheless, his ability as a low-usage wing who excels in three-point shooting and defensive commitment remains unparalleled. Since the 2020-21 season, O'Neale has successfully made 724 three-pointers at a shooting percentage of 38.8 percent while maintaining a usage rate just above 12. Notably, this places him at the lowest usage rate among players with similar efficiency and volume, with Grayson Allen being the next closest at 15.5. O'Neale's capacity to shoot effectively while defending the opponent's top offensive threats speaks volumes about his value, albeit often overlooked.

Isaiah Hartenstein, who has moved past this ranking following his lucrative three-year, $87 million contract with the Oklahoma City Thunder, presents an intriguing case. The context surrounding Hartenstein's contract is frequently neglected; a team option on the final season suggests this is essentially a two-year commitment. Throughout the past five years, Hartenstein has demonstrated exceptional versatility on the court—from executing screens effectively and rebounding to defending the rim and facilitating plays. His defensive prowess could very well have earned him an All-Defense selection if not for his minute restrictions. Standing 10th in Value Over Replacement Player (VORP) among players averaging over 20 minutes per game without an All-Star nod showcases the tremendous impact he has made.

Other players match Hartenstein's rebounding (18.2), assist (14.8), and block (4.4) rates, namely Anthony Davis and Victor Wembanyama, who has only been active for two years. Hartenstein’s time spent with major market teams like the Los Angeles Clippers and New York Knicks has raised his visibility, yet his contributions throughout five teams in five years underscore a sizable impact that exceeds common valuation.

Josh Hart faces considerable criticism for his deficiencies, particularly for his inconsistent three-point shooting. However, his tenacity and relentless hustle contribute positively to his team's performance. Despite challenges in his latest season, which can be attributed to the lineup configurations of the New York Knicks, Hart consistently enhances his team’s offensive pace and provides dynamic play in transition. His true shooting percentage of 58.7 is above league average, while only three players, including Bam Adebayo and Luka Dončić, match his defensive rebounding, assist, and steal rates, indicating his substantial role in shaping team identity.

Derrick White's presence in this conversation, particularly at second place despite his recent rise in discussions for All-NBA recognition, might raise eyebrows. While recognition does not equate to an official All-NBA designation, White continues to operate outside the perception of a conventional star. Over the past five years, he has significantly refined his offensive skills, improving decision-making and developing a more reliable three-point shot, alongside the elite defense he is known for. Crucially, he has demonstrated an ability to effectively perform when not sharing the floor with superstars Jayson Tatum and Jaylen Brown, establishing himself as a top contributor.

Ivica Zubac gained recognition for both Most Improved Player and Defensive Player of the Year consideration during the previous season, demonstrating a culmination of his gradual improvement. Zubac's adept defensive skills and positioning have allowed him to excel, finishing in the 90th percentile for rim points saved per 100 possessions for multiple seasons. His recent breakout reflects sustained growth rather than a one-off achievement, particularly given his significant defensive performance compared to other players with similar minutes.

These insights aim to illuminate the impact of players whose contributions have often been overshadowed by marquee names. Each of these athletes plays a crucial role within their teams, symbolizing the essence of cooperation necessary for championship aspirations in the NBA.
