There is another aspect to the story that people aren't talking about and that is the role the media has played during all of this. If Izzo is guilty of covering up some egregious behavior, then he's guilty. If that means this is too much of a circus right now and you can't have him coaching the team, fine. I think that makes sense. Some things come before basketball.
But why is it somehow noble to grill a coach with questions you know he can't answer in a post game press conference? Do people get warm feelings when this kind of thing essentially becomes a back and forth at recess? Because these resignations are the result of public pressure and not justice. The scene at that press conference is taking at delicate legal process and moving it to the cafeteria so that some reporter has the chance to be a hero, despite the fact that the very negligence of the media contributed to the Universities ability to cover this up in the first place. Why? Because it wasn't as convenient then.
Michigan State is clearly guilty and Tom Izzo might be. The common denominator is always the media being obnoxious, chasing page clicks, and establishing narratives that predate facts. That is the cause and whatever happened at Michigan State is the symptom. Until the American public starts to realize what is going on here, injustice is just going to be perpetually re-distributed.
