I think there is a reason football players are paid million to run around a field tackling each other over a ball. There is a really good chance you will get hurt. Is it just me or is this even stupider than people being able to sue cigarette companies. Why wouldn't repeated trauma to a sensitive organ cause damage then and in the future? Why did they even need to do a study to prove it? The players are claiming the NFL withheld the knowledge that repeated concussions can cause future permanent damage. Didn't their doctors ever warn them about this? Lets say these football players are such dumb fumbling idiots that didn't figure it out themselves, I think it should have been the responsibility of the doctor to warn them repeated concussions are bad for their health. Thats like a woman getting blood clots repeatedly and her doctor not warning her that her birth control pills are the culprit and in the future a clot could cause a Pulmonary embolism and kill her. I wonder how many of them would go back in time and give up the fame and fortune they earned by getting all those concussions and try their luck at some other career? This is even stupider than people that sue tobacco companies after they get cancer.
