It was actually going to be cheaper to for TCU to travel in the Big East then it was in the MWC. I think the travel cost are blown way out of proportion. Most of the Big East schools are located in major metro areas, you can fly into them and have a very short drive relatively easy. CUSA is the same way with the exception of Marshall and Southern Miss. In most cases you are talking about a 2:00 vs 3:00 flight. It's really not that big of a deal, most people on this board are making it a big deal because they want it to be a big deal. In this article it states that the Big East doesn't require schools to compete in individual sports against other Big East members during the regular season. So if SMU or Houston doesn't want to ship their golf team, tennis, or swimming teams to Piscataway, NJ or wherever for regular season matches, they don't have to. I believe they would just have to compete in the conference tournament.

Who knows where college football will be in 5 years, we might not even have conferences. Who knows. I just think if you can move up a rung in status, you do it regardless of the finances but I don't think the financial situation is as dire as people here are making it out to be.
