That success carried over to his coaching days, when he won three titles (one as an assistant, two as a head coach) during Boston's run of success in the 1980s with Larry Bird & Co.

Jones is one of only seven players to win an NCAA title, NBA title and Olympic Gold Medal.
"The Celtics family mourns his loss, as we celebrate his remarkable career and life," the Celtics said in a statement.
