That's understandable. What about the university of Huston? Large city with no schools in the power 5. Yes, they probably don't fit for an alumni base, academics, geographically, and many other reasons but I'm just trying to think outside the box here.
If the big ten expands I would like to see them move into richer recruiting territory (preferably closer to Nebraska vs the east coast). Adding another Iowa school or a Kansas school doesn't help in that aspect.
