Also saw someone say that the only non-bowl team Osborne lost to was 1992 ISU but can't find it now.
After 10 minutes on Wikipedia, this claim is false by a long ways. TO technically lost to 8 teams that didn't go to a bowl. But the total is probably really 7 as we lost to OU in 1990 when they were on probation so they couldn't go.
1974 Wisconsin in Madison
1974 Missouri in Lincoln
1976 Iowa St in Ames
1976 Missouri in Lincoln
1977 Washington St in Lincoln
1984 Syracuse in Syracuse
1992 Iowa St
1990 Oklahoma in Norman (OU finished 8-3, but didn't go to a bowl game due to probation)
