No, this is just the NFL playing then "we care" card in a CYA move. At some point, I believe they will need to play the "look at all the things we've enacted for the safety of the players" card to counter how people will react to the knowledge they had about concussions and still sent players back in the game. They are guarding that information with everything they've got because if the public, not necessarily fans, finds out what they knew and when they knew it, there will be an accounting.
I am pretty much caveat emptor with pro football but I do think they need all of the information. I don't think it will deter many as only one young player has hung it up, that kid from the Niners.
What I don't get is how is this any different from auto racing, boxing, MMA which all have risks involved? Anyone watch a pro game and think that looks like a safe way to spend a Sunday afternoon?
The real issue for me is how they treated the players back then with rung bells and frowning on any second opinions to the point of job security. But the knowledge of the impact of concussions was dark ages back then but we know they would do anything to a player to get him back in the game. Those guys were treated like pieces of meat but today's players have a lot of people looking out for them, they can afford it.
