1) I think you should include WSU and OSU as a MW school. They are basically playing a MW schedule. WSU beats Texas Tech and UW. Interesting that Texas Tech then beats both Iowa St and ASU. By my count the top MW schools went 3-1 against the B12.
2) The B12 a is P4 lite conference filled with recent G5 schools and former bottom tier PAC schools. Former Pac12 cellar dwellers ASU and Colorado now football giants? Iowa St a record setting year? Or just a a result of a bunch of average teams thrown together in the same conference?
