I can see reading comprehension isn't a strength of posters on VN. So, once again...I am asking about college football, and specifically about major conferences in college football. Pro football is completely different. Lots of coaches are fired in pro football and go on to find success with another pro team or in the college ranks. So citing Spurrier, Gruden, Carroll, Saban (???), etc, has nothing to do with my question.
So far, I have two answers. And neither were fired in the last 25 years (and actually Holtz shouldn't technically count, because he wasn't playing in a major conference with Notre Dame, but I'll allow it on the basis of common sense).
