During Thursday Night NFL football games, the NFL has been tracking player attributes, such as speed, acceleration, movement direction and jump height with chips embedded into shoulder pads of various NFL players.
According to Polygon's, Samit Sarkar and Madden
"Ratings Czar" Donny Moore, this data could be released to EA Sports to "potentially revolutionize" player ratings.
It probably won't happen any time soon, since the NFL is only tracking a handful of players, but it's fun to speculate.
