Boston Celtics Hall of Famer Sam Jones, “Mr. Clutch,” who won 10 championships in the team’s most dominant era, died Thursday night of natural causes. He was 88 years old. Jones was a standout at North Carolina Central University and was originally drafted by the Minneapolis Lakers in 1956, but he went back to school after a stint in the military, which negated the selection. He was then drafted by Red Auerbach, sight unseen, in 1957.
