So the NFL can't figure out how to deal with, or just plain deal with domestic abuse, but just wear the wrong brand headphones and you will feel the wrath of the commissioner. The NFL is run by a bunch of sociopaths.
Just how would one count how many phones are encrypted or not? What would be the reason to count them? Maybe to see which phones you could extract information from. It seems to me that if you have no interest in the data, why would you even know who is encrypted or not.
