Retired

The Boston Celtics have existed since 1946. In that time, they've retired 21 numbers, from 1 (for original owner Walter Brown) to 00 (for ageless center Robert Parish). Assuming that numbers are used in their normal fashion, there are 101 possible combinations of jersey numbers: 0-99 and 00. And assuming that the Celtics continue to retire numbers at their current pace, they'll be entirely out of them sometime during the 2229-'30 season. Assuming (and it's a big assumption) my math is correct. So Boston, please, stop the madness before it's too late. Don't make our grandchildren have to root for numbers 1.4 and -6.
