In 1957, rookie center Bill Russell joined the Boston Celtics, which already featured guard Bob Cousy and coach Red Auerbach, and went on to lead the franchise to eleven NBA titles in thirteen seasons. Center Wilt Chamberlain entered the league with the Warriors in 1959 and became a dominant individual star of the 1960s, setting new single-game records in scoring (100) and rebounding (55). Russell's rivalry with Chamberlain became one of the greatest rivalries in the history of American team sports.
