An in-depth report from Frontline and ESPN's Outside the Lines describes the fight for Junior Seau's brain following his suicide last year—a fight that ESPN reporters Mark Fainaru-Wada and Steve Fainaru, who are working on a book and documentary about brain injuries in football, call "a scientific backroom brawl." Seau's brain was the highest-profile and most sought-after yet, and the Seau family was barraged with calls—some within hours of his death—from researchers who wanted to study it. "It felt sometimes to me like buzzards were circling," says the deputy medical examiner who performed Seau's autopsy.
