OSU/WSU had option of sending their teams to MWC for "other" sports.
We need to remember that OSU/WSU have to do something after this year or they will lose their status. So, this could be considered temporary and my big question is why would WCC do this for just a year? Head scratcher. If MWC didn't turn them down on "other" sports, then you have to imagine they're a little insulted to not be offered an arrangement with their other sports.
A whole lot up in the air on this subject.
