Change is a natural part of life, or at least that's what my doctor keeps telling me. 

Seems to me that the Big Twel is rapidly heading back to its Big 6 roots, just with Texas in the mix.  Wetzel on Rivals.com suggests that TCU should renege on its Big Least deal and join the Big Twel.  Does make sense.  If Okla goes to the SEC, though, that could be the death of the Big Twel.  In which case, Texas might just go independent (they have their own network) and the remaining schools might look for some appropriate replacements.  BYU would probably lead the list, with maybe Houston (nice TV market), Memphis and Tulsa some other possibles.  CUSA might then go for schools like App St. (if they go 1A), Florida Atlantic (Miami market) and maybe Temps.  I don't see North Tex moving up; they barely tread water in the Sun Belt.  A MAC/CUSA merger doesn't make sense, either.  Too many teams, too geographically diverse, just too unwieldy.
