Is banning blitzing next?

Since this is alledgly about "player safety", there are tons of data about concussions suffered by quarterbacks that have led to memory loss. Brett Farve recently stated he's suffers from memory loss from the hits he taken over the years. Since most team can't sack or hit the QB without blitzing, wouldn't this reduced concussions? Silly notion but when do this silly "player safety" stuff stop? It's a freaking unsafe sport. Maybe if they just make players sign a waiver of liability, they can avoid lawsuits and these dumb rules to protect players.
