You know, this is a path these athletes choose and why they get paid a lot of money as professionals. They know when they start playing that concussions are a risk they might have to face - just as cops know they risk getting shot on the job or firefighters facing the risk of burning to death. Yet they still took those jobs.
It's time for sports leagues to recognize that their athletes are highly rewarded, monetarily, for the risks they face and stop trying to legislate injuries out of their games because that is an impossible endeavor.
