1) Bob Devaney preceeded Tom Osborne and won two natty's. It wasn't a one coach run.
I was going to make the same point. Nebraska's run wasn't just the 25 years with Tom Osborne as HC.
Bob Devaney coached Nebraska for 11 years from 1962-1972 and, as
@iahawk15 pointed out, won two NC's (1970, 1971). His run was arguably more impressive than Osborne's:
- 9-2, 3rd place in Big8, won Gotham Bowl over Miami in 1962
- 10-1, Big8 Champ, won Orange Bowl over Auburn, finished #6/5 in 1963
- 9-2, Big8 Champ, lost Cotton Bowl to Arkansas, finished #6/6 in 1964
- 10-1, Big8 Champ, lost Orange Bowl to Bama, finished #5/3 in 1965
- 9-2, Big8 Champ, lost Sugar Bowl to Bama, finished #6/7 in 1966
- 6-4, 5th in Big8 in 1967
- 6-4, 4th in Big8 in 1968
- 9-2, Big8 co-Champs, won Sun Bowl over Georgia, finished #11/12 in 1969
- 11-0-1, Big8 Champ, won Orange Bowl over LSU, finished #1/3 in 1970
- 13-0, Big8 Champ, won Orange Bowl over Bama, finished #1/1 in 1971
- 9-2-1, Big8 Champ, won Orange Bowl over Notre Dame, finished #4/9 in 1972
That is a SERIOUSLY impressive run and if you look at the period of 1962-1997 Nebraska's winning percentage is #1 by a LARGE margin over #2 Penn State for those 36 years.
Even after Osborne retired, three of Solich's first four Nebraska teams finished in the top-10. Solich's six teams finished ranked five times and top-10 three times along with a NC appearance but he got canned because the program appeared to be heading in the wrong direction.
Nebraska's long term history is unusual. As discussed above, they were phenomenal from the hiring of Bob Devaney in 1962 through about 2001. Prior to Devaney they were flat awful for decades. They had been very good from the early 1900's through the 1930's then just flat sucked in the 1940's and 1950's up until Devaney came along in 1962. Then they were arguably the best program in the nation for about forty years (1962-2001). Then, of course, they were decent under Pelini but the Riley era was not good and so far Scott Frost hasn't managed to finish .500 or better.
In the modern (post-WWII) era they have:
- Two coaches who were best-in-the-nation level good (Devaney, Osborne)
- Two coaches who were good but not great (Solich, Pelini)
- Nine coaches who have flat sucked:
- George Clark in 1945
- Bill Glassford from 1949-1955
- Pete Elliott in 1956
- Bill Jennings from 1957-1961
- Bill Callahan from 2004-2007
- Mike Riley from 2015-2017
- Scott Frost from 2018-2020 (so far, maybe?)
