Unseld was a 5-time NBA All-Star, an NBA MVP in 1969, and a 2-time NBA All-Defensive Team selection. He also revolutionized the center position, leading the Washington Bullets to an NBA Championship in 1978 and was named Finals MVP. He is well known by most NBA fans, so I think it's worthy to have him in the quiz.
yeah but im pretty sure most people doing this quiz aren't over the age of 65. If there's gonna be old players there should be some that even young people know, like Wilt or Bill Russell.
