Re: NFL players experimenting with military grade EXO Skeleton CRT pads in their helm
There is enough money and focus on this issue that I think some type of break-through technologies are in the not-to-distant future.
CloakNNNdagger mentioned brain airbags, maybe facetiously, but I think there will be some kind of genetic and/or other tech that comes along to "upgrade" players to reduce the effects of traumatic head impact.
The NFL is trying a 'grassroots' effort right now to teach correct mechanics to little league players. But the head sloshing around in the skull will still be the same. The only way they can truly protect the brain will be something that is inside the skull, not outside of it.
