Basketball almost assuredly has to be an extreme outlier here though, in that outrageously rare physical attributes are almost a necessity to play competitively. I realize there have been some exceptions with very small players but they seem rarer and rarer each year. This doesn't invalidate your point, but we might get a more accurate picture if we only looked at people who ended up 6'3, strong and athletic.
