Does anybody know:
Do any NBA stars have their numbers retired in multiple NBA franchises?
Julius Erving got his number 32 retired by the Nets and number 6 retired by the Sixers. Oscar Robertson got his number 1 retired by the Bucks and number 14 retired by the Kings.
Those are the only two that I know of.
Players with numbers retired with multiple teams:
Wilt Chamberlain, Lakers, 76ers, Warriors
Kareem Abdul-Jabbar, Bucks and Lakers
Charles Barkley, 76ers and Suns
Clyde Drexler, Blazers and Rockets
Julius Erving, Nets and 76ers
Michael Jordan, Bulls and Heat (yep, Heat)
Bob Lanier, Bucks and Pistons
Moses Malone, 76ers (unofficially) and Rockets
Pete Maravich, Jazz and Hornets
Oscar Robertson, Bucks and Kings (Royals)
Nate Thurmond, Warriors and Cavs
