Sunday marks the 20th anniversary of the death Len Bias, the former Northwestern High star and University of Maryland All-American who overdosed on cocaine at the age of 22, just forty-eight hours after he was selected by the Boston Celtics as the second pick in the NBA draft.

Fraser Smith, author of Lenny, Lefty & the Chancellor: The Len Bias Tragedy and the Search for Reform in Big-time College Basketball and sports commentator Milton Kent.
