Winning, of course, is the question.
They will not. It would destroy all pro sports ($$$)
Actually if it goes to trial the players WILL win because in the early 90s the league published a report that said there was no evidence of long term side effects from head injuries. The league lied to them, in official documentation, they will lose. But it won’t go to trial, because Goodell came up the PR side of the house and he knows how bad the PR hit will be with a trial even if they win.
