THE LESSER OF A POSSIBLE EVIL by ST

My first reaction to hearing about the former NFL Players bringing legal action against the league was "come on"!  You really didn't know this game was dangerous?  Now with more information being made available about the long term impact, I'm backing way down.  Much will come down to what the owners and league knew prior to the rest of us.  Obviously the in game risk of broken limbs and damaging injuries was common knowledge.  What about the long term impacts to the brain and quality of life?  I harken back to the era when tobacco was regularly promoted and a key advertiser in sports.  Turns out they knew it was poison but lied about it in the name of profit.  We now see the folks at R.J Reynolds or Philip Morris as evil.  The NFL owners are multi-millionaires and billionaires.  Are we really putting it past them to offer an information blockade in the name of massive profits?  Seems like an issue worth pursuing.  Very curious to hear your thoughts on this.
