Age: 23 (Nov. 18, 1963 – June 19, 1986)
Cause of Death: Cocaine overdose

Len Bias was one of the most dominant college basketball players in the country during his time in Maryland; he was a two-time All-American and two-time ACC Player of the Year. The Celtics, that year’s NBA champions, selected him No. 2 overall, which would have put one of the game’s best young players on a team with Larry Bird, Kevin McHale, and Robert Parrish.

But just two days after he was drafted, Bias died of a cocaine overdose at just 23 years old. It’s hard to imagine the 80s Celtics playing much better than they did, but if Bias had lived, that could have very well been the case.
