NBA to Test New One Free Throw Rule, Sensor Basketballs at 2026 Summer League
Key Points
The One Free Throw Rule could disproportionately affect players who are strong 3-point shooters but less reliable at the free throw line, potentially advantaging shooters with favorable combinations of 3-point and free-throw efficiency (e.g., Anthony Edwards) more than others like Stephen Curry.
The connected basketball includes an embedded sensor that detects contact with the ball, with the explicit assurance that the sensor does not alter the ball's weight, feel, or playability, while providing data to support officiating tasks such as last-touch-out-of-bounds calls.
There is skepticism about how much the One Free Throw Rule will actually shorten game times; some observers suggest it may not create a meaningful dent in length, underscoring the need for real-world data from the Summer League tests.
Fan and analyst reactions include concerns that the rule could reward inefficient free-throw shooters, with discussion noting that certain players with slower or less reliable free-throw routines might be affected in unexpected ways (as highlighted in coverage of the rule's reception).
The NBA will test a sweeping free-throw overhaul at the 2026 Summer League, replacing standard multi-shot sequences with a single attempt worth the full point value of the foul — two points, three points, or one. The Independent reports the rule will apply at tournaments in Salt Lake City, Northern California, and Las Vegas, with standard free-throw rules still in effect during the last two minutes of regulation and overtime.
Alongside the rule change, the NBA will trial a connected basketball with an embedded sensor designed to aid officiating. Chicago Tribune reports the sensor can detect contact with the ball — useful for last-touch out-of-bounds calls — without changing the ball's weight or feel.
One Free Throw Rule Aims to Cut Game Stoppages
The core idea is simple: instead of shooting two or three free throws, a player shoots once. That one shot is worth however many points the original foul would have produced. A foul on a two-point attempt becomes one shot worth two points. A foul on a three-pointer becomes one shot worth three. SB Nation notes the NBA G League has already used this rule since the 2019-20 season.
Supporters say fewer free throws mean fewer stoppages and faster games. But some observers are skeptical. Yahoo Sports notes the rule may not create a meaningful dent in game length, which is why the NBA wants real-world Summer League data before making any wider decisions.
Some Players Stand to Gain More Than Others
The rule could shake up scoring for certain players more than others. A player who shoots 80% from the free-throw line and 40% from three now gets one shot worth three points instead of three separate attempts. That changes the math fast. Yahoo Sports highlights Anthony Edwards as a player who could see a bigger impact due to his strong three-point shooting but lower free-throw reliability.
Meanwhile, elite shooters like Stephen Curry — who excel at both free throws and three-pointers — may see less dramatic change. Critics also worry the rule could accidentally reward players with slow or inconsistent free-throw routines, giving them one high-value shot instead of multiple chances to fail.
Embedded Sensor Basketball Targets Officiating Accuracy
The connected basketball carries a sensor inside that tracks when and where the ball is touched. The NBA's primary use case is last-touch calls — determining which player touched the ball before it went out of bounds. The Independent stresses the sensor does not change the ball's weight, feel, or playability in any way.
The technology is being tested alongside the free-throw rule as part of a broader push to modernize officiating. If the sensor proves reliable in Summer League play, the NBA could expand its use to support a wider range of real-time calls in future seasons.
NBA Uses Summer League as a Rule-Testing Laboratory
Summer League has become the NBA's go-to testing ground for experimental changes. The low stakes make it ideal for collecting data without affecting playoff races or team standings. Chicago Tribune reports the one-free-throw rule is explicitly designed to speed up play, echoing a league-wide focus on game flow that has driven several recent rule adjustments.
Whether either change reaches the regular season depends on what the data shows. The NBA will weigh pace gains against fairness concerns and strategic effects before deciding next steps. For now, the 2026 Summer League serves as the first real-world test for both ideas.
