I collected some “Best Athletes of All Time” lists off the Internet and combined them into one list.  Because I only found a few such lists, I supplemented with sport-specific “Best Athletes” lists.  First, I organized the results by rank, that is, by the number of lists the athlete was on.  To see the list, go here.  Michael Jordan was on 17 of the 20+ lists I found, giving him the Number 1 spot.  The list below is organized by sport and within each sport by rank (the number of lists the athlete was on is in parentheses), and within rank by date of birth.  Where men and women both compete in the sport, but compete separately, I have separated the men and women.
