Just a few comments for what it's worth... it has been my experience that college recruiters do in fact look at the PG rankings. They very much want to see the player in live game action...
True story... son was working out with his team he is a jr... he asked the recruiting coach, "Hey where did the freshman play high school ball" the coach then said, I can tell you their hometown and their travel team, i have no idea about their high school team. I would have to look it up.
I know our HS coach told me last winter there were 11 D1 commits in our league over the offseason and only one of colleges contacted the HS coach. The other 10 were signed from summer ball. One kid was an ACC commit before he played a single varsity game, he apparently had a couple good AB's vs a stud in GA and is very projectable...I wish there was futures market because that kid IMO has little no chance of helping the school he is going to. I would say he is about 90/10 to leave after freshman year.
