Leonard Kevin "Len" Bias (November 18, 1963 – June 19, 1986) was a first team All-American college basketball forward at the University of Maryland. He was selected by the Boston Celtics as the second overall pick in the 1986 NBA Draft on June 17, but died two days later from cardiac arrhythmia induced by a cocaine overdose. He is considered by some sportswriters to be one of the greatest players not to play at the professional level.
Bias was born in Landover, Maryland. He was known to friends and family by his childhood nickname "Frosty". He was given the nickname by his good friend and pastor Rev. Gregory Edmond because he was "tall and cool and quiet and unassuming"
As a freshman, he was viewed as "raw and undisciplined", but developed himself over time into an All-American player. In his junior year, he led the Atlantic Coast Conference in scoring and was named the ACC's Player of the Year. His senior season was highlighted by his performance in an overtime victory against top-ranked North Carolina in which he scored 35 points, including 7 in the last 3 minutes of regulation and 4 in overtime. At the end of the year, Bias collected his second ACC Player of the Year award and was named to two All-America teams. 
Bias impressed basketball fans with his amazing leaping ability, his physical stature and his ability to create plays, and was considered one of the most dynamic players in the nation. By his senior year, scouts from various National Basketball Association teams viewed Bias as the most complete forward in the Class of 1986. According to Celtics scout Ed Badger, "He's maybe the closest thing to (Chicago guard) Michael Jordan to come out in a long time. I'm not saying he's as good as Michael Jordan, but he's an explosive and exciting kind of player like that." Jordan was then in his second professional season with the Chicago Bulls.
On June 17, Bias was selected by the defending NBA champion Celtics as the second overall pick in the 1986 NBA Draft, which was held in New York City at Madison Square Garden. Arnold "Red" Auerbach, as the Boston Celtics President and General Manager, had previously dealt guard Gerald Henderson and cash to the Seattle SuperSonics for the pick in 1984. After the draft, Bias and his family returned to their suburban Maryland home.
On June 18, Bias and his father flew to Boston, Massachusetts, from Washington, D.C., for an NBA club draft acceptance and product endorsement signing ceremony with the Celtics' coaches and management. Bias had discussions with Reebok's Sports-Marketing Division regarding a five-year endorsement package worth $1.6 million. 
After returning home to Washington, Bias retrieved his newly leased sports car and drove back to his room on the campus of the University of Maryland. He then dined with some teammates and a member of the football team. He left campus at approximately 2 AM on June 19 and drove to an off-campus gathering, which he attended briefly before returning to his dorm in Washington Hall at 3 AM. It was at this time that Bias and some friends used cocaine. According to the campus timeline, Bias had a seizure and collapsed sometime between 6:25 and 6:32 AM while talking with teammate Terry Long. At 6:32 AM, when the 911 call to Prince George's County emergency services was made by Brian Tribble (a long-time friend), Bias was unconscious and not breathing. All attempts by the emergency medical team to restart his heart and breathing were unsuccessful. After additional attempts to revive him in the Emergency Department at Leland Memorial Hospitalin Riverdale, Maryland, Bias was pronounced dead at 8:55 AM of a cardiac arrhythmia related to usage of cocaine. It was reported that there were no other drugs or alcohol found in his system after his death.
Four days after his death, more than 11,000 people packed the Cole Field House, the university recreation and student center where Bias played for the Terrapins, for a memorial service. Those speaking at the service included Red Auerbach, who said he had planned for three years to draft Bias for the Celtics. Auerbach added that the city of Boston had not been so shocked since the assassination of John F. Kennedy. Bias is buried in Lincoln Memorial Cemetery in Suitland, Maryland. On June 30, 1986, the Celtics honored Bias with their own memorial service, giving his never used #30 Celtic jersey to his mother, Lonise.
