Too much money being made for NFL to go away. They'll figure something out whether it be better equipment or changing some rules. Everything is one-sided against football right now. I'm sure a test will be developed in near future for CTE in live patients and the actual cause of CTE will be honed in on. NFL has almost unlimited money to solve a problem that threatens its survival. Probably at a low point right now, but I'll bet on NFL figuring it out.
