I hear ya, and it's always good to leave the door open a crack. But unless the HR files were water-damaged during Hurricane Andrew (a distinct possibility in 1992), I don't see much hope here.
I think the Coaches Clinic is a different thing. And as far as I recall, Coach O was never barred from any team reunions/anniversaries or anything like that. I always liked the dude, he is an intense, well-meaning, hard-nosed guy who just has some impulse issues with ladies and/or liquor.
I wouldn't mind him being the first student in the Saban-Cristobal Coaching Rehab Clinic (East Campus), but it seems very unlikely.
