Unearthing Hidden Gems: Discovering Diamond Players through NBA Draft Analytics


In the world of professional basketball, the NBA Draft is akin to a grand lottery. Teams are making multi-million-dollar bets on players, often teenagers, whom they hope will become high-quality pros. Amidst this unpredictable process, a concept from baseball, known as "Moneyball," has made its way to the basketball court. This approach, popularized by the Oakland Athletics and their general manager Billy Beane, relies heavily on statistical analytics to evaluate player potential.

In the NBA, these "Moneyball"-style analytics are still a work in progress, but they have begun to provide valuable insight into which players to choose and which to avoid. While the hurdles and pitfalls are numerous, the potential rewards are huge. One of these rewards is discovering what we call "diamond players" or hidden gems - players who might not stand out initially but possess immense potential that could be unearthed through careful analysis.

The Emergence of Analytics in the NBA Draft

The NBA Draft has historically been governed by traditional scouting methods, including personal workouts, interviews, and background checks. However, the rise of big data and advanced analytics has revolutionized this process. Teams are increasingly turning to statistical analysis as a tool for evaluating prospects, albeit this method has not completely replaced the old-fashioned scouting methods.

The introduction of analytics into the draft process has not been without challenges. Some teams have mis-evaluated prospects despite the use of analytics, indicating that the art of choosing players is still an inexact science. But despite these obstacles, thoughtful consideration of player measurables such as box score stats, physical attributes, and age, can help teams unearth overlooked gems and provide a much-needed corrective to the sometimes-deceiving eye test.

The Value of Analytics in Identifying Prospects

There are instances where analytics has shown its value in identifying prospects. Case in point, the 2012 draft prospects, Jae Crowder and Draymond Green. While they were not seen as highly-rated prospects by traditional scouting standards, statistical analysts believed otherwise. Today, both players have proven their worth in the NBA, validating the predictive power of analytics.

Key Statistical Categories in Player Evaluation

Statistical analysis in player evaluation extends beyond the basic numbers. There are several key statistical categories that analysts consider when evaluating prospects:

  1. Blocks, Steals, and Two-Point Field Goal Percentage: These are markers for applied athleticism. Guards need a two-point percentage above 50 percent, while big men need to be close to 60 percent.

  2. Overall Offensive Efficiency: An offensive rating below 110 points produced per 100 possessions is a red flag, regardless of position.

  3. All-Around Production: Big men with high assist numbers tend to be valuable NBA players. Similarly, guards who rebound well often transition well to the NBA.

  4. Free Throw Shooting: This can be a better indicator of a player's shooting prowess than three-point percentage, which can often be skewed by small sample sizes in college and international hoops.

However, knowing which numbers matter the most is not enough on its own. Any reasonably predictive analysis also has to place those numbers into an appropriate and useful context.

The Process of Using Stats to Evaluate Prospects

In using stats to evaluate NBA prospects, several steps and considerations are crucial. First, defining the question is essential. For example, does the general manager want to know who will contribute immediately, or who will have the best overall career? These different questions may yield different answers.

Secondly, understanding that college and international stats aren't one-size fits all is important. The level of competition matters, and two players with identical stats can have markedly different pro potential depending on the opposition they faced.

Lastly, it's crucial not to dismiss top performers from bad teams or those who produced against lesser competition. These players can often be overlooked but may possess untapped potential that could be uncovered with careful analysis.

Case Studies of Success Stories

While there are numerous examples of players who were overlooked in the draft but went on to have successful NBA careers, two notable examples include Manu Ginóbili and Draymond Green. Ginóbili was selected with the 57th pick in the 1999 NBA Draft, and Green was the 35th pick in the 2012 NBA Draft. Both players have had successful careers, with Ginóbili winning four NBA championships with the San Antonio Spurs and Green winning three with the Golden State Warriors. These examples highlight the potential of analytics to uncover hidden gems in the NBA Draft.

It's important to note that while analytics can provide valuable insights, it's not an infallible system. There will always be outliers and exceptions, and human judgment plays a crucial role in player evaluation. Therefore, the combination of data-driven insights and traditional scouting remains the most effective strategy in the NBA Draft.


The NBA Draft is an exciting and unpredictable event, with teams hoping to secure the next big star. The integration of analytics into the draft process has added another layer of complexity, but also another tool for teams to use in their quest to find the best players.

While "Moneyball"-style analytics is still a work in progress in the NBA, it's already showing its value in unearthing hidden gems and helping teams avoid potential busts. The future of the NBA Draft could see an even greater emphasis on analytics, as teams continue to refine their methods and use data to inform their decisions. The art of finding diamond players through analytics is a challenging but rewarding endeavour, one that has the potential to redefine the landscape of the NBA Draft.
