The Celtics chose the opener to honor a champion fans still connect to the banners
NBC Sports Boston reported that the Boston Celtics wore the "19" patch on their left shoulder during Tuesday's game against the Detroit Pistons to honor Don Nelson. Nelson won five NBA championships with Boston in 1966, 1968, 1969, 1974 and 1976, and the Celtics retired his No. 19 in 1978. He is one of 23 Celtics players with a retired number.
Don Nelson joined Boston as a free agent before his third NBA season and became one of the best sixth men in league history. The forward averaged more than 10 points per game in Boston before the 3-point line existed, and his steady scoring helped the Celtics stay on top through two different championship eras.
