Perhaps the final basketball-related stop on Don Nelson’s 50-year journey comes Friday in Springfield, where the former Celtic — and the NBA’s all-time winningest coach — will be inducted into the Naismith Hall of Fame.

Nelson, 72, spent 30-plus seasons as an NBA coach, winning three Coach of the Year awards and leading 18 of his teams to the postseason. It’s an accomplished career, one littered with fast breaks, thrilling moments, and franchise reclamations.
