My wife and I saw "Concussion" starring Will Smith saturday. I don't know enough to judge its accuracy, but it pulled no punches in criticizing different NFL officials. Nor did it minimize the harrassment the researcher received.

The movie made the point that the human brain lacks the natural protection found in some animal species, so a large number of hits over years can hardly fail to affect it.

In spite of these ideas, players these days seem more intent than ever, in my 67-year-old memory, on intimidating opponents with targeting, etc. Unsportsmanlike conduct penalties seem to be proliferating more than I can recall. I suspect football will face some major problems over the next 15-20 years.
