The Warriors won the inaugural Basketball Association of America (BAA) championship in 1947,[c] and won again in 1956, led by Hall of Fame trio Paul Arizin, Tom Gola, and Neil Johnston. After the trade of star Wilt Chamberlain in January 1965, the team finished the 1964–65 season with the NBA's worst record (17–63). Their rebuilding period was brief due in large part to the Warriors' drafting of Rick Barry four months after the trade. In 1975, star players Barry and Jamaal Wilkes powered the Warriors to their third championship, widely considered one of the biggest upsets in NBA history.
