Meh, just because something has a higher risk than doing nothing doesn't mean it will go away completely. This is all being blown out of proportion because the "plaintiffs bar" is prepping/propagandizing to justify lawsuits, like the class action one I posted the other day.
As we have discussed before, a helmet redesign could IMO make football safer vis a vis head injuries. We made the helmet a weapon in the '50s and that was not a good thing. The guy who invents a soft helmet with equal or superior impact protection and crush resistance is going to revolutionize football. Players won't want to lead with their heads anymore so they won't. If you look at old football films from the early 50s and before it looked more like rugby technique (leading with shoulder, arm tackling).
