"League of Denial: The NFL’s Concussion Crisis" investigates allegations that the National Football League denied and refuted scientific evidence that violent collisions are linked to early onset dementia, long-term brain damage, death and other consequences for players. Journalists Mark Fainaru-Wada and Steve Fainaru discuss the findings they uncovered while co-writing their book "League of Denial: The NFL, Concussions and the Battle for Truth."
