not really, its largely based on the logical thought that the devaluation of a P5 exclusive March Madness tournament is drastic enough to prevent the P5 schools from collectively doing so. They might make more money by excluding everyone else but that tv contract would be so much less, plus if they were to split they risk losing non-profit status which loses them even more money. I'm sure some schools will be for it, but many won't be. Plus, can you imagine the media fallout from doing so? Good luck sifting through that PR nightmare. "What do you have to say about gutting one of the longstanding traditions in college athletics?". Lol no amount of money makes up the amount of negative press the P5 schools would receive for making a move like some of you are suggesting.
You avoid this problem by including the BE and the A-10 and MWC + the best from the MVC and MAC in this conversation. Again, as a longtime supporter of college basketball, I would find a Big East + best of the G5 or whatever tournament more compelling than a tournament that features first round matchups between schools like Rutgers and Utah. Many would agree with me, I am sure. And not just my buddies who are supporters of Big East programs. Maybe I'm old school in my way of thinking. I will leave my arguments at this and bookmark this thread, we'll see who is right in 25 years when the current tournament contract expires.
