Don Nelson, the Hall of Fame coach who won five NBA championships as a Boston Celtics player and later became the league's second-winningest coach, died Sunday at age 86. The Golden State Warriors, one of the teams he coached, announced his death.
Nelson, known for inventing the up-tempo style called "Nellie Ball," won three Coach of the Year awards during his career. He is one of two coaches in NBA history to record at least 250 wins with three different franchises: the Milwaukee Bucks, Dallas Mavericks, and Golden State Warriors. He also served as general manager for all three teams.
His regular-season coaching wins rank second all-time in NBA history.
