Here is my suggestion as to how to have a quick and fair hearing and attempt to make sure that the current cheaters don't benefit from their cheating.
1. Have the Big Ten collect the documentary and computer evidence and give it to Michigan and ask whether it is valid. Giving Michigan about 3 weeks to reply as to whether it is authentic or not. Also give Michigan 3 weeks to answer the question of whether Stalions spied for Michigan at specific games. If there are legitimate questions, then give Michigan more time -- whatever is necessary. Personally, I think that is unlikely with 95% of a lot of sources whose credibility is at stake reporting the same thing.
2. In the event that Michigan is found guilty give it a substantial in season penalty in roughly 2 weeks after the 3 week deadline. If they have been cheating as a lot of circumstantial evidence shows the current players and coaches need to be penalized.
3. Would also mention the Paterno matter and incorrect jump to judgment there has little bearing here. Cases of child sexual abuse are fraught with complicated questions such as the accuracy of children's statements and the passage of time. The Michigan sign stealing situation is much clearer than the matter of which many have commented on here.
4. Also due process in the legal sense does not require extensive legalistic hearings. [And shouldn't be applicable anyway since the Big Ten is a private entity.] "Such hearing need not take the form of a judicial or
quasi-judicial trial, but the recipient must be provided with timely and adequate notice detailing the reasons for termination, and an effective opportunity to defend by confronting adverse witnesses and by presenting his own arguments and evidence orally before the decisionmaker."
