All NFL Players Will Now Wear Motion Trackers On The Field

Last year the NFL started testing out wearable motion-tracking chips which record the movements of players on the field, including how they execute plays to their speed and distance, according to BuzzFeed Sports.

As of the 2015 season, all 31 NFL stadiums will have sensors installed that work with the chips to track every player's move in real time.

According to Zebra Technologies, the maker of these chips, the trackers are extremely accurate and have a margin of error of less than six inches.
