It's amazing how the love of money will skew facts and policy. Boxing, football, cage matches, etc., may be around til Jesus comes ---- IT'S THE MONEY!
Regarding football concussions, science may come to the rescue. I read where they're designing helmets that will reduce concussions. Maybe we'll see future football players wearing NASCAR type harnesses or something similar.
This safe-helmet might come....but by the time you figure the cost, and the court fights on high school football, NCAA football, and pro-ball....it’ll be too late. You could be looking at tens of billions to pay off the lawyers and players. TV advertising will never be able to pay enough for the NCAA or NFL to survive this...my humble opinion.
