Rensselaer is now 2A and Pioneer is a small 1A and not a 4A that they are listed at here. I believe KV and Boone Grove are classed wrong.
What happens in 3 years when the "balance of power" changes completely to a different part of the State? Do you move everything again? Evansville has been deep recently, but I can remember when East Chicago/Merrillville was just as deep. Things change too often to revamp based on what we are seeing now.
I know it is hypothetical, but Rensselaer does not have the facilities to host a regional. Unless you only allow one parent per wrestler and no other fans.
