Long before Junior Seau hung up his NFL spikes, he was a legend. Seau had everything an athlete could ever want: the adoration of millions, the admiration of his peers, the love of a beautiful family, and a sense of purpose beyond the playing field. And yet, on May 2nd, 2012, at age 43, Seau, alone in his bedroom, shot himself in the heart. He left no suicide note, offering no clear answers to why he'd take his own life. Now, ESPN’s 30 for 30 film Seau seeks those answers, exploring his remarkable path out of an immigrant Samoan family to NFL stardom, and the many complications that ensued through two decades of playing a brutal and unforgiving game.

Documentary filmmaker Kirby Bradley – who co-created HBO’s Real Sports with Bryant Gumbel series – had done a lot of reporting on concussions and CTE syndrome as the showrunner of Real Sports. After learning that Junior Seau’s brain revealed CTE, he felt compelled to tell his story. Kirby can discuss the new film, the incredible life and career of Junior Seau, what we’ve learned from his story, and ultimately where the responsibilities lie.
