Hall of Fame basketball coach and former NBA player Don Nelson dies at 86, his family announces. Multiple outlets report that he is remembered both for five NBA titles as a player with the Boston Celtics and for a long coaching career across several franchises.

As a coach, Nelson is described as a league innovator whose systems and approach influenced later NBA strategy. Sources also highlight that he ranks near the top of NBA history for regular-season wins, with some noting he is the second-winningest coach in league history and that he won NBA Coach of the Year multiple times. Several accounts add that he coached four NBA teams—Golden State, Milwaukee, New York, and Dallas—across multiple decades and that the Celtics retired his No. 19 jersey.

Outlets differ mainly in emphasis and wording, with some focusing on his championship record, others on his coaching influence or standings among all-time winningest coaches. CBS and others also note his Hall of Fame status and his Celtics legacy, while reports from Cyprus Mail and Inquirer.net state that the family confirmation does not disclose where he died or the cause of death.
