George Fox wow! I was surprised that they didn't get an At large bid for the Regionals.
I can only speak to D2 #5 on the list UIndy, but their field is tiny. Its like 170-180 at the lines and 190 in CF. I also know they can't go back further. Its already mashed into a street corner. My guess is the D2 outlier Valdosta St also has a short field. Thats a crap ton of HRs.
