I think the regions is the best idea. I would not travel very far out of state to see Iowa State wrestle this year, but I will be in Ames (or if it was in Iowa City, UNI, or Minneapolis) to watch the regionals. I think the same is true for a lot of the fans, esp outside the top 5. I also like to wrestle teams that we normally don't see during the season, Oregon State and Wisconsin. I would not be thrilled to have Iowa, UNI, Minnesota, Iowa State, Missouri all in the same region. I understand that we have to have some overlap, but Iowa State already wrestles the Big 12 twice, plus Big 12 tourney, I don't want any in National dual regionals.
A mix of western schools (Wyoming, Boise State, Cal Poly, Oregon State) and Big 10 schools (Illinois, Wisconsin) would be great. I am excited that Iowa State will see Wisconsin and the hopefully Oregon State (2 teams we haven't and don't normally face) in regionals.
Just my thoughts for the future!
