Step-by-step explanation:
The League of Denial documentary is about the controversy and denial surrounding the link between football-related head injuries and long-term brain damage. The documentary explores how the National Football League (NFL) denied the existence of a connection between concussions and chronic traumatic encephalopathy (CTE), a neurodegenerative disease.
It presents evidence from medical studies and interviews with former players, scientists, and NFL officials to highlight the extent of the problem and the NFL's attempts to downplay it. The documentary serves as a critique of the NFL's handling of the issue and raises awareness about the long-term consequences of head injuries in contact sports like football.
