"Last time I had this conversation with someone it was at the plastics show in Orlando with a guy who makes the padding in the helmets. I asked what's holding them back from making a helmet that cuts down on concussions and got two points back..."
A point of clarification: Helmets can't completely prevent concussions (I do understand you were asking about cutting down, not preventing), because you don't necessarily have to be hit in the head to get a concussion. Whiplash can cause it. Concussion is not caused by the brain hitting the skull, as is often believed. It's a disruption in the network of communication between cells when the brain is jostled or moves suddenly.
Helmets, of course, do help protect against skull fracture, and very well may help reduce incidence of concussion. And as you pointed out with the Virginia Tech study, design does matter.
Apologies if this has already been discussed/clarified before.
