The 15 Most Damning Quotes From 'League Of Denial,' The NFL Concussion Documentary

On Tuesday, PBS aired the much anticipated "Frontline" documentary, "League of Denial: The NFL's Concussion Crisis."

The documentary is based on the book "League of Denial: The NFL, Concussions and the Battle for Truth," written by brothers Mark Fainaru-Wada and Steve Fainaru.

It is an excellent look into uncovering the link between football and brain injuries, and the NFL's efforts to protect its brand and deny the connection and danger of their sport.

If you haven't seen it, you can watch the entire documentary at PBS.org.
