Well now the problem is these "consenting Adults" at the Pro Level who get paid over 380k at a minimum want to sue everybody because they got concussions.
I have no problem with people doing what they wish wherein they might get hurt. I do have a problem with them suing someone because they bashed their brains around and now think they are entitled to a payoff.
If you ask most ex-NFL players if it was “worth it”, the VAST majority say yes. Just to get to play at that level.
