The NFL is evolving in ways many never would have considered 10, 20, 30 years ago.
In conjunction with all 32 teams, the NFL will "require players to wear non-obtrusive tracking devices in select practices and games," according to a league memo sent to the clubs on Aug. 1.
The tracking devices will use various technologies to monitor "positional and performance data," including speed, distance traveled, and field locations.
Data collected from these devices will not immediately be shared with the clubs, as the league plans to work with the Competition Committee on how to best evaluate and distribute the information.
The Buffalo Bills have been using similar technology for close to a year, and feedback has been positive.
"They talk about the distance you covered and the explosiveness and how fast you're running," running back C.J. Spiller told BuffaloBills.com. "It's a good device to have."
According to the memo, it is likely that all players will be required to wear them "at some point over the next few seasons."
