Which on one hand, the school can pretty much do whatever it wants. Because attending the U of Minn is not at all a right, and losing your student status really amounts to nothing. You don't lose your freedom, you don't get fined, and it's not a civil suit either. With so "little" at stake, the burdens of proof and the "fairness" of the process can essentially be arbitrary.
And that's what we see.
But in the case of student-athletes, obviously if you lose your student status, you lose the ability to be an athlete. That is an additional consequence (as would be for any member of any school sanctioned/sponsored extra-curricular activity). But in the case of football and men's basketball (maybe men's hockey and baseball too), you're potentially talking about putting a huge dent in the student's ability to make a lot of money as a professional athlete. Makes me wonder if there shouldn't be a law in the state requiring the process to have a special consideration and/or special process when it involves losing something more than "just" being a student. Maybe a lawsuit will force that, one day. We'll see I guess ...
