That pic, by the way, being shown, doesn't tell me a damn thing. There are a hundred guys on the sidelines with cameras during a game. And another thousand in the crowd.I can see a few in the picture. Trying to control who takes video during a game is a bit ridiculous--though the people on the field have to have credentials of some kind to be there.
I don't know much about it, but I would imagine offensive and defensive signals are changed every game, and even every half. Teams know enough to do that.
I haven't seen a single story in the media which explains all this stuff, and asks the important questions. What is the value of taking video during a game?
