Three of the top 4 are from Ohio. 4 of the top 6. Out of 25, 5 are from Ohio.

Though Illinois has more schools with 6 rated, I am of the opinion that they ignored Ohio after putting all those teams at the top. I suspect that 8-10 Ohio schools could have easily been up there:

I see where another ranking includes Mentor in the top 25 nationwide.
