A new New York Times investigation has revealed the National Football League hid more than 100 diagnosed concussions and then published studies based on the flawed data. The Times exposé casts significant doubt about the validity of the NFL’s studies. The investigation also exposes deep ties between the NFL and the tobacco industry, showing that the two industries shared lobbyists, lawyers and consultants. In a statement, the NFL accused The New York Times of publishing “pages of innuendo and speculation.”
