There are no current NBA or CBA players who wear the number 59. In fact no one has ever wore the number 59. It is not a common jersey number, as many of the jersey numbers happen to feature lower numbers.
Number 2 was retired in honor of Chuck Daly, Head Coach, 1983-92. Daly never played in the NBA; the number 2 represents the two NBA championship teams he coached.
