NFL tests new experiment at Del Valle spring scrimmage
(CBS4) -- A strange gadget made an appearance in Del Valle's offensive huddle on Friday. It belongs to the NFL.
"A lot of teams are starting to use [virtual reality] to train their quarterbacks and linebackers," Walt Anderson, a 23-year NFL Official told CBS4's Eric O'Brien. "The NFL office wants to see if that same type of technology can be used to train officials."
What appears to be a Rubik's Cube on a stick is actually six GoPro cameras which can provide a full 360-degree perspective from on the field.
