The NBA is investing in the study of wearable GPS devices with the probable end goal of having players wear them during games.
The league is funding a study, at the Mayo Clinic in Minnesota, of products from two leading device-makers: Catapult and STATSports.
Most teams already use the technology during practices.
Weighing less than an ounce, these devices are worn underneath a player’s jersey. They track basic movement data, including distance traveled and running speed, but the real value comes from the health- and fatigue-related information they produce.
Several GMs and other team higher-ups have privately pushed for in-game use, but they understand the league has to collectively bargain that kind of step with the players’ union.
There is a concern on the part of the players' union on how teams uses the data and who gets to see it.
