Re: Future of the NCAA
No school/conference will break away unless they know for certain they could make more money than they are currently making. Breaking away and being an independent conference or new NCAA-type organization would likely lose the tax exempt status and I think the taxes alone would be enough to scare them from leaving the NCAA.
As for due process, the NCAA does have their own version of it. Allegations -> investigation -> findings/sanctions -> appeals -> appeal decision -> enforcement of any sanctions. Only in the most egregious situations (ie Penn State) do they circumvent that process.
