The NBA isn't the only professional sports league in the States getting serious about accurate stats accounting. With some help from Zebra Technologies' location system, 17 NFL stadiums will use receivers and RFID (radio-frequency identification) tags inside player's shoulder pads to track movement. The setup provides real-time position data for each player, offering up precise info on acceleration, speed, routes and distance as part of the "Next Gen Stats" initiative for fans. Referees are getting the tags too, in case you've ever wanted more info on those fellas. "Zebra's tracking technology will help teams to evolve training, scouting and evaluation through increased knowledge of player performance, as well as provide ways for our teams and partners to enhance the fan experience," says NFL VP of Media Strategy Vishal Shah. The 15 venues that are hosting Thursday night games are getting outfitted, with Detroit and New Orleans added in to make sure each team gets tallied.
