You are counting on TCU, Houston, and Tulane not jumping to the MWC. Word is TCU will have an invite very soon and that the MWC is courting the other two. If they go...well, get the respirator, the CUSA's failing fast.
Welcome to the fray, Virginian, and allow me to echo the questions by Javaman. Having not heard any discussion of Houtson or Tulane jumping to the MWC, this concept surprises me completely. Tulane will rediscover their athletics, but not at the expense of their academic status and reputation. And while maintaining an affiliation with TCU (and serving as a travel partner for them) may soften the concept of them switching conferences, it seems more unlikely now with the additional Texas schools coming to CUSA from the WAC.
Further, the articles posted on this board indicate the MWC is thinking of only adding 1 school, two at best, with Boise and Fresno St. leading the pack after TCU. The prospect of schools moving to either CUSA or the MWC is to abandon the geographic disparity that plagued the WAC. Should those three schools join the MWC, you'd essentially be recreating that same problem, IMO.
Granted, I wouldn't put it past these conferences to do anything, based upon some actions already taken! :D
