Head Injury Litigation: Why No NCAA?

For precisely the point of liability and lawsuits. If the NCAA has recommendations and guidance for the schools but doesn't actually require the schools to do anything - it's then on the school if concussions are mismanaged. If the NCAA instead requires the schools to do certain things and those things may be shown to be harmful or at least less effective than other measures that should have reasonably been required, the NCAA is far easier target because it was the one that mandated how concussions were managed.

So isn't there some negligence in that way of thinking? Would the NFL be less liable if they left concussion management up to each team?
