Where are the teenagers ? (Top 100 getting older and older)
maybe there are more players in their 30s still playing than there used to be.
They simply take up spaces. The ones taking up the ranking spots 75-250 -- probably about 40-50 spots. If they retired, spots would open up and younger players would trickle down.
I don't think so. Ok if the teenagers can't break into top 10, that would be way too much, but if they can't even break into top 300, then it's probably because they are simply not good enough.
