I think when you are looking at all 3 teams you could have went in any order at first glance. My initial thought would have been USD, NDSU, SDSU
USD played a d2 school and unfortunately had a game cancelled and SDSU also played a d2 school. At second glance I would have placed NDSU 2 and since the comparison is now just between the South Dakota Schools, SDSU won head to head so they are 3 and USD is 4.
