Your first point stood out too me, since the #1 player in the State/ IU Commit Dasan McCullough and his brother are both on Bloomington South. Which should cause a lot of problems with Castle this year. Even Bloomington North should be a little tough too. Though I am high on a Castle postseason, they could be bounced after the first round depending their opponent.
Your second point is another well one too. And could be a big hit on Castle if the rumors are true, due to OT Virgin transferring to Gibson Southern
