The Mavericks are among eight NBA teams to commission the services of GPS tracking devices from the Australian company Catapult Sports, which hails itself as the leader in “athlete analytics.” The devices track player movements and body vitals and are designed to optimize training efficiency and mitigate injury risks.

“We just want to be able to get smarter about our players and how to train them and how to put them in a position to succeed,” said Mavs owner Mark Cuban. “So that’s just one component of a lot of different things that we’re doing.”

Athletes wear a cell-phone sized device on the inside of their jerseys between their shoulders, and it records their every movement in all directions as well as their heart rate. This gives coaches what Catapult’s Gary McCoy describes as a “dashboard” for players’ bodies.
