ZDNet went behind the scenes at the recent Seattle Seahawks versus Oakland Raiders matchup in London to see how Zebra Technologies is tracking and tracing player movements. Zebra has embedded RFID tags in players' shoulder pads to analyse movement, providing metrics such as player speed, distance travelled, acceleration, and deceleration.
"It's one thing being able to measure a 40-yard dash by a player with a stopwatch -- that's pretty simple to do," says John Bacon, director of operations for NFL's Next Gen Stats at Zebra Technologies. "But if you need to do that for 22 people simultaneously, well that would take an army at best -- even if you could do that. The technology provides the capability to track the position of every player at all times within inches."
