Even if the MWC went to a nine game schedule that would still leave 3-4 games OOC to schedule top teams. Sure you'd be playing Wyoming and NM. But every Indy schedule so far has had it's crap teams as well, that's not going to change. In reality an Indy or MWC schedule is going to be the same mix of good, middle, and bad teams every year. You looking forward to playing Middle Tennessee St and Savannah St this year? Those teams get you more excited than Wyoming and NM?
There are arguments for staying Indy, however, we'll never be able schedule tough enough in the MWC is not one of them.
