Derek Boogaard : the rise and fall of a hockey enforcer

Hockey is back for another season. And with that, comes the archetype of the enforcer. From Airforce to Slap Shot, pop culture has been full of portrayals of enforcers as cartoonish goons. But in recent years that perception has shifted to something more tragic. In 2011, three tough guy players died over a four-month stretch. Derek Boogaard, who was an enforcer for the Minnesota Wild and the New York Rangers, was one of them. He was only 28 when he died of an alcohol and drug overdose while recovering from a concussion. Day 6 talks to New York Times journalist and Pulitzer Prize winner John Branch, who wrote the critically acclaimed new book, Boy on Ice: The Life and Death of Derek Boogaard.
