No one knows if any girl will be "D1 Good" until 16U ball.
I don't know. On my DD's 14U team, it was pretty clear who was on track to play at the D1 level (higher skill level, work ethic, etc.). Of those, all of them are except the one who decided not to play college ball - my kid. There were a couple of others who had such ridiculous natural athleticism at a young age (12U), that there was little doubt they would end up D1 if they continued in the game. Both did.
