Even if what's alleged in those letters is half true, the whole WBB coaching staff has to go. Just sickening. And it has to be done now. No excuses, no qualifications.
In terms of MT, I agree that he has to be put on a short leash, but he should go if it becomes clear he knew but did not do anything about it. One of the letters mentioned they spoke to him about it but didn't seem to specify the timeline. If he wasn't aware, then I'm willing to give the benefit of the doubt.
Even with the ebbs and seemingly more ebbs of the Illini athletics program, I've always been proud of the fact that we run a clean program that holds integrity and academics above all else. SC's allegations are still, in my opinion, largely unsubstantiated. This seems very much the opposite, and admin will need to make it clear that they will work to restore faith of the staff, student, and alumni base.
