To be clear, I don't blame these schools AT ALL for breaking away. But I'm far from convinced that this will lead to unification. Once the private schools leave, the pro-split people will get exactly what they wanted all along - a public-only association. And at that point what's their incentive to try and reunify?
I'm also really curious to know why the new organization is limiting membership to 60 teams. A rule like that doesn't signal a will to unify.
