The problem isn't ever the odd number. You can always find the odd number. There's always a relatively attractive #11, #13, #15, etc. It's the even number that you have trouble with.
Cincy is kind of a slam dunk at this point. They have a really strong basketball program that you can add to an already strong basketball conference. They are adding lots of facility upgrades. Nippert is getting a nice overhaul, 5/3rd is getting one or will get one. If you need more capacity than Nippert will allow, there's always Paul Brown.
WVU needs a regional rival. They're strong academically. They have a very competitive football program with access to a solid recruiting base in Ohio and the PA area. They'd be more than fine.
But what do you do with #12? BYU as football only? CSU? Memphis?
I've been anti-CSU for a long time, but honestly, they may be the best all-around fit. Decent basketball, had flashes of a strong football program over the years, and they're making efforts to improve their standing. A $200 million stadium facelift doesn't hurt. Really solid academics.
Memphis has the potential to kind of explode a bit. NFL sized city with no NFL team. Memphis basketball is always a big draw. They can recruit well in both sports. However, the academics are really a downside from an expansion standpoint.
I think you can potentially do Cincy and Colorado State, and you won't look completely stupid. It won't look great, but they've got time to develop into better programs. I don't think there's much you can do with UCF at this point. They're just too far out there, geographically. I get all of the arguments, but I mean, man, that's just going to be a big issue.
I think if they do it, it will be Cincy and CSU or Memphis. I'm not sure what other options there really are that this point. I don't think there are any.
