Only one man has been inducted into the Basketball Hall of Fame twice—John Wooden.
He was enshrined the first time in 1960 when he was cited for his accomplishments as a star guard at Purdue from 1930–32. Wooden captained the Boilermakers his junior and senior years and was Player of the Year in 1932, the school's only national championship season.
In 1972 he was honored again, this time for his coaching achievements at UCLA. Ordinarily, Halls of Fame wait until an all-time great has retired before they hand him a plaque, but Wooden's eight NCAA championships were anything but ordinary, so they elevated the Wizard of Westwood now.
