NBA’s Data Revolution: How 3D Tracking is Reshaping the Game

The NBA is undergoing a profound shift, moving beyond familiar scouting and film study to leverage sophisticated data analytics. Fueled by advancements in 3D tracking technology, strategies are evolving, player movement is becoming hyper-optimized, and even the role of the referees is being reimagined.

The Rise of the 3-Point Shot and Data Optimization

Even before the implementation of “3D” tracking, the game was already trending towards a greater emphasis on the three-point shot. As Dean Oliver, the creator of the ESPN Analytics Group, highlighted, “Even before the arrival of the third dimension, the effects on the game were already sensitive, with in particular an acceleration in attack, to create open shots.”

“We are in the optimization of shoots,”

This emphasis is reflected in the dramatic increase in three-point attempts over the past fifteen years— a doubling in attempts, driven largely by data-based insights. As Milwaukee Bucks superstar Damian Lillard noted during the All-Star Game, “The whole league is far away in data analysis.”

“We tell you: we only want three points or lay-ups, no two-point shots. This removes part of its originality from the game,” Lillard stated, emphasizing a strategic prioritization of higher-percentage scoring opportunities. “You cannot play in a way if everyone plays another” he added. “You have to line up with what works to win.”

Commissioner’s Response and the Need for Change

The scale of this transformation has prompted a response from NBA Commissioner Adam Silver. “There is still a lot of margin of improvement in data analysis,” Dean Oliver said. “We have a mass of data (drawn from 3D capture) but we have not yet converted it into knowledge that can be relayed to players.”

Silver has acknowledged the need for adjustments, stating that the league is actively studying ways to limit the standardization of the game – effectively addressing concerns about a potential homogenization driven by analytic over-reliance.

AI’s Expanding Role – From Offense to Defense

The focus is currently heavily weighted towards offensive optimization, but the potential of artificial intelligence (AI) in defense is generating considerable excitement. “Late” compared to the attack, consultant Tom Ryan sees AI as a key area of development. The league is investing in projects utilizing “head-on” analytics and AI, particularly in the realm of arbitration.

“Our ideal, it would be to be able to use the sensors to say, for example, which lastly touched a shot in touch, rather than having to watch the sequence,” describes Tom Ryan, referencing a revolutionary approach to officiating. “For a referee to make the same observation, it is a question of making decisions (arbitral) with more acuity, faster and with transparency for fans.”

Beyond Officiating: Diversifying Fan Engagement

The transformation isn’t limited to gameplay and officiating. The NBA is actively exploring ways to leverage this data to enhance the fan experience. A prime example is the Christmas Day matchup between San Antonio and New York, which featured an alternative, real-time retransmission in the form of a video game, powered by AI.

“We want to sell our sport, argues Tom Ryan, and present it in attractive forms.”
