I get that as well that is why I say the NFL would have to force it. I played football in high school and did get my fair share, I can only imagine the speed increase at college and NFL.
Some indicator would help get past the problem of the helmet obscuring player sense. Assisting the player back to the feeling of not having a helmet while they do, in terms of peripheral vision sense, behind you and around you would be nice. If you don't have a helmet on and someone rushes up behind you in a game they are easier to see without a helmet. Just knowing someone is there is enough to prevent concussions. It is the blind shots where someone doesn't expect it that can really cause problems. Head on collisions usually aren't as bad because of both players awareness. If there is some way to inform the player of players around them within a range I think would help immensely and if it is very out of the way the players would deal, especially the previously concussed.
It could be some pretty cool tech, almost drone/neural network like combined with gaming elements connecting player helmets and pads (they do have some indicators tracking players on shoulder pads now - http://mashable.com/2014/07/31/nfl-shoulder-pad-sensors/). But I agree it would have to be forced on the player by the NFL only, no team or player would do it without the NFL forcing the changes. Awareness of players on the field is one of the biggest deterrents to concussions, anything the NFL can do to help that would be good for their case.
