In 1999, the late Wilt Chamberlain became the first player to have his number retired by three teams when. The Golden State Warriors retired his no. 13 jersey at halftime of their game against the Philadelphia 76ers. The no. 13 jersey was presented to Barbara Lewis and Yvonne Chamberlain, Wilt’s sisters, and Oliver Chamberlain, his brother. Chamberlain’s number had already been retired by the Philadelphia 76ers, where he was part of the 1967 NBA championship team, and the Los Angeles Lakers, where he was part of the 1972 title team. Chamberlain spent six years with the Warriors organization, averaging 41.5 points and 25.1 rebounds in 429 games. The legendary center dominated in the paint and is the only NBA player to have averaged 30 points and 20 rebounds throughout the course of his entire NBA career. Chamberlain guided the Philadelphia 76ers to a championship in 1967. In that six game finals series against the San Francisco Warriors, Chamberlain averaged 17.7 ppg and 28.7 rpg. Chamberlain’s other accolades include a second championship with the 1971-72 Los Angeles Lakers, 7x NBA Scoring champion, 11x NBA Rebounding champion, 4x NBA MVP, and 13x NBA All-Star. Chamberlain was inducted in the Naismith Memorial Basketball Hall of Fame in 1979.
