I would throw my Alma Mater in there at the moment. Miami University. They set the foundation for greatness of "small" schools back in the 70s by beating three straight SEC teams in bowl games, a huge upset of LSU in 1986 and an AP Top Ten ranking in 2003 with Roethlisberger, and was on the list of the Top 25 all time wins, but have now since hit the crapper since 2003 (save for a couple bowl games 2010,2016). Did have 6 straight wins last year, but gift wrapped the bowl win last year to Mississippi State, have now lost 12 straight to the Bearcats and off to a grim 2-3 start this year. The climb back to respect seems to still be a mountain in front of us!
