Well, I can't lie, I don't know anything about the legal issues at stake here and what the NCAA can or cannot do - and I realize you have a much better grasp of that than me.
I'm just going based on my own common sense - and I don't have a problem with the NCAA heavily penalizing a member of its association for egregious violations of the ethical code and culture it aims for. The NCAA has a right to look out for the NCAA.
Just like I don't have a problem with Goodell punishing players for reflecting poorly on the NFL - but again, I don't truly know the relationship between NCAA and team, or how that relates to the Goodell example.
There's clearly going to be nothing about this in any charters for this specific situation. But, like I said above, we have at least one example of them policing culture - so there is SOME precedence.
