Tom Osborne was the head coach at University of Nebraska-Lincoln for a quarter of a century. He was not only an amazing coach that led our team to 3 national titles, but he consistently displayed sound moral character, good sportsmanship, and did amazing things in the community. Yes, he was idolized and looked up to as a hero - he still is - but it is even more than that. He gives people something to really believe in and to model - kids and adults alike.
I also knew him (in the 80s) personally. I would find it a stretch to name one person I admire more.
If Tom was not only accused of covering up something like this but there was also solid proof, I would be seriously devastated. It would be very very hard to reconcile what I personally know and have experienced with what people were "saying". I wouldn't however disregard the evidence and blindly continue to support or excuse him.
