Ok, might get flamed for this, but here goes.
Think about it for a second. You're say... University of Houston (or pick any other non-BCS conference school) and you have a chance to be a part of the Big XII. This is a no brainer right? Lets look at the pros and cons
More TV exposure
More $$$ for how long?
Conference instability (2 teams gone, 1 other pretty much out, and a few others flirting with other options)
Unequal revenue sharing
Questionable commissioner. While Bebe may have saved the Big XII last year, he certainly has his negatives.
The pros sure are tempting, but would anyone want to jump in feet first to this unstable conference?
