Can we all just agree that Frank has been a very good mid major coach and was a great assistant coach at Nebraska and leave it at that? Both of those things are elite accomplishments that he and his family should be extremely proud of and there are a limited number of people that could do either of these things as well as he has. Very impressive feats.
In hindsight, he was a great head coach at Nebraska. He never had a losing season, won a Big 12 title in 1999 and had three finishes in the top ten. NU has not won a conference title or had a top ten finish since. We may never again. There are no guarantees - Frost or no Frost.
While clearly not the same challenge Frost faces, Frank did have to do some rebuilding. Much of Tom's old guard left between 2000 and 2003 - some retired, some let go. Firing Frank before he was allowed to fully transition from Tom's old staff and succeed or fail on his own accord is the biggest mistake in NU football history and ground zero for the dismantling of Nebraska football.
