Lewis' contract remained on the Celtics' salary cap for two full seasons after his death because at the time the NBA did not have a provision to void contracts in the event an active player died; NBA Commissioner David Stern said that the remaining NBA teams should approve an exemption for Lewis' contract but the rest of the league, many of whom had spent years or even decades losing to the Celtics on the court, said that they would do no such thing to help Boston. The rules have since been changed so that a similar case would result in a deceased player's contract being paid by league insurance.
