Inside the next era of player tracking

A few seasons ago, most player tracking systems treated an athlete as a single dot sliding across a grid. In 2026 the leading systems model the whole body: elbows, knees, hips, the bat in a hitter’s hands and the stick in a skater’s. The NBA pulls 29 data points per player from optical cameras. MLB measures the speed of every swing. The NFL plans a camera system to sit beside the chips in its shoulder pads. Each step changes what coaches can measure, what officials can rule on and what shows up on your screen.

From dots to skeletons: how optical player tracking works

The NBA made the jump first among the big U.S. leagues. In March 2023 the league and Sony announced a multiyear deal with Hawk-Eye Innovations, starting with the 2023-24 season, ESPN reported. Hawk-Eye replaced Second Spectrum’s “center of mass” system, which estimated each player’s spot on the floor from one point. The new setup uses pose tracking, following limbs and joints in three dimensions. Sportradar, the league’s exclusive data provider, works with Hawk-Eye to turn that feed into data sets and advanced stats.

The scale is large. When the NBA announced its partnership with Amazon Web Services in October 2025, it said its tracking captures 29 data points per player, and that one new metric processes optical tracking data 60 times per second.

Hockey runs on similar hardware. Hawk-Eye has operated in every NHL arena for about a decade through its replay service, and its cameras capture 29 skeletal points on each player plus three on each stick, according to an Associated Press report from June 2025.

Baseball got there in 2020. MLB installed Hawk-Eye at all 30 ballparks that year, with 12 high-frame-rate cameras per park, TV Technology reported. The system measures points on the body 30 times per second and tracks the ball to within a tenth of an inch. It powers Statcast.

Why the NFL still tracks players with chips

Football took a different route. According to the NFL’s operations site, each player carries two or three RFID tags in his shoulder pads, and 20 to 30 ultra-wideband receivers ring each stadium. The tags report position 10 times per second. Officials, pylons, the chains and the ball carry tags too, for about 250 devices per game. The league says every play produces more than 200 new data points.

A February 2026 SiliconANGLE analysis laid out how far the program has grown. The NFL runs more than 75 machine learning models at once, and broadcast models must return results in under 100 milliseconds. The same report says the league plans an optical system built on 4K camera arrays that would track more than 30 points on each player’s body. Chips tell you where a player is. Cameras can show how his knees bend when he plants to cut.

The data also shapes rules. SiliconANGLE reports that tens of thousands of simulated games informed the dynamic kickoff and the ban on the hip-drop tackle. Our breakdown of NFL Next Gen Stats in 2026 covers the newest models in detail.

New AI stats built on player tracking data

Raw coordinates mean little until a model interprets them. For 2025-26 the NBA and AWS launched a platform called NBA Inside the Game with three new metrics, per the league’s announcement:

• Defensive Box Score names each offensive player’s primary defender in real time, so the box score can credit the defender. It also logs double teams, switches and ball pressure.
• Shot Difficulty rates how hard each attempt is and adds an expected field goal percentage that weighs defensive pressure and the shooter’s setup.
• Gravity measures how much defensive attention a player pulls, with or without the ball, and the space that opens for teammates.

A tool called Play Finder searches player movement across thousands of games to surface similar plays. Teams get direct access to the underlying models, and broadcasters get real-time alerts with historical context. You can read more about the league’s season plans in our NBA tech guide for 2026-27.

MLB added the bat to its picture in May 2024, when Baseball Savant began publishing bat tracking leaderboards. Statcast measures bat speed at a point six inches from the head of the bat. Any swing at 75 mph or faster counts as fast. A “blast” is a swing that is both fast and squared up. Swing length measures the total distance the bat head travels before contact.

Player tracking moves into officiating

The same cameras that feed stat sheets now help settle calls. MLB’s automated ball-strike challenge system, which finished its first regular season in 2026, runs on 12 Hawk-Eye cameras per park, according to MLB. The Premier League switched on semi-automated offside on April 12, 2025, using optical player tracking built with Genius Sports to place the offside line, NBC Sports reported.

The NHL is moving slower. Commissioner Gary Bettman said the league would use tracking for calls such as high-sticking and goal-line decisions “When we’re certain that it works,” per the AP. NHL executive David Lehanski said the answer will likely combine sensors in the puck or jerseys with optical cameras. Hawk-Eye CEO Rufus Hack described the work as early stage.

What player tracking changes for fans

You see the output most clearly in streaming broadcasts. Prime Video’s AI-powered Prime Insights feature serves catch-and-shoot three-point percentage, dribbles per shot and half-court pace during NBA games, and it flags when an offensive player has a favorable mismatch, Sports Video Group reported in April. The alternate Prime Vision feed adds an above-the-rim camera and more overlays, and producers use it to test features before they reach the main broadcast. On Thursday Night Football, Prime shows tracking-based metrics such as Pressure Probability, per SiliconANGLE.

Numbers like Gravity and Shot Difficulty give fans something concrete to argue over during a game. That debate is the core of FansPulse, where live game rooms and creator commentary run alongside the action. For more on how models turn tracking feeds into insight, browse our AI coverage.

The NHL has given no date for using tracking in officiating, and the NFL has not said when its camera system will go live. SiliconANGLE describes the NFL’s planned arrays as tracking joints including elbows, knees and hips, the same body points the NBA and NHL already capture.
