Quick Summary

Don Nelson, the NBA's second-winningest coach and former player for the Boston Celtics, has died at 86. He had won five championships as a Celtic and coached over 250 games with three different franchises: Milwaukee, Dallas, and Golden State. During his coaching career, Nelson was a three-time coach of the year and made the playoffs 18 times in 31 seasons. His unorthodox "Nellie Ball" offense, which emphasized speed and the fast break, helped teams such as the Bucks (where he won seven straight division titles) and Golden State's "Run TMC" era succeed under his guidance.
