Logistically I don't think hosting games at college campuses is feasible. Some towns and cities might not have the budget to handle an extra, heavy police presence for example. Someone is going to foot that budget? You get 4-6 weeks advance notice? Good luck on getting that through some small towns' red tape on short notice, especially with christmas and new years, and 4Q/usually fiscal year-end accounting sucking up cycles.

Also, what if the city of Memphis has some big country music event sucking up 75% hotels when the Tigers sneak in. What in police overtime restrictions are already in place due to budget woes in whatever city?

I just think when you open it up to 8, the G5 is going to start howling for guaranteed representation. Regardless, 8 opens up the pool of colleges so much that there could be all kinds of headaches in all kinds of unforeseen ways.

I don't see it going past 4. I especially don't see any plan to pass that involves hosting post-season games on college campuses.
