The one benefit that Arian Foster has that the others didn't is that he can see how concussions are leading to some rather awful living conditions for ex-NFL Players, so he can make an informed decision, which makes this kind of thing a good idea for the NFL's future. The past players don't have the same amount of data to draw upon when it comes to the long term health effects, because who would collect it, but neither should they should be shocked by the deterioration of the body, either.
