What jumped out to me was that, for 4A/3A girls, only five defenders out of 36 players were selected.

That's not a statement about any of the names selected. But it seems that a team on the field is usually made up of 36% defenders, but the All-State selection only selected 13% defenders. So it seems, just based on those numbers, that there is a heavy bias towards offense and points, not necessarily impact.
