ESPN 30 for 30: Seau (9 p.m., ESPN) - Directed by Kirby Bradley, this 30 for 30 documentary shows the highlights of NFL great Junior Seau’s football career while foreshadowing the tragedy that would befall him. The deeply loved player retired from the league in 2009, drove his SUV off a cliff in California in 2010 (and survived), and took his own life in 2012 by shooting himself in the chest. Seau’s family agreed to have his brain studied, and the National Institute of Health determined he was suffering from chronic traumatic encephalopathy (CTE) at the time he died. Bradley’s film explores the Samoan Hall of Famer’s life and death, the obstacles he faced, and the legacy he left behind. Watch the trailer of “Seau” here.
