I've always thought of the brain damage as a given; concussions will cause damage, the brain's a little "iffy" on the healing front, and severe concussions are basically unavoidable in football. If you care about whether you get hurt: Don't play, don't let your kids play, and so on.

It was much more interesting to hear how much the NFL had covered up, and the degree to which they directly lied about the evidence of the effects of playing the game.

The cover-up is the scandalous part, so of course that's the part that people are going to focus on.
