The league tested Sony's Hawk-Eye tracking services for virtual line-to-gain measurements in the preseason and in the background during the regular season. The optimal tracking system notifies officiating instantly if a first down was gained after the ball is spotted by hand.
The key word is after. This technology replaces the chain measurement. The NFL has long used two bright orange sticks and a chain -the chain gang to measure for first downs. That method would remain in a backup capacity.
"What this technology cannot do is take the place of the human element in determining where forward progress ends," NFL executive Kimberly Fields told last weekend. "There will always be a human official spotting the ball. Once the ball is spotted, then the line-to-gain technology actually does the measurement itself. So I think it's probably been a point of confusion around what the technology can and can't do. There will always be a human element because of the forward progress conversation."

Fields said an average of 12 measurements took place each week during the regular season. The new technology would've dropped the time spent to measure from 75 seconds to 35 seconds.

They provide various data and metrics that help clubs, media and fans with player evaluation and analysis of team performance. But these chips can't determine where a player ...
