From 1973 through 1992 Nebraska was 17-33 against top 10 opponents and even worse against top 5 opponents. Michigan is a top 10 team year in and year out as is OSU. Even if we have a legendary coach, a unique system that is hard to prepare for, amazing facilities, fan support, and a system of broadcasts that prioritizes our program above others...we still won't beat top 10 teams but 1 out of 3 times. The 1993-1997 huskers are not the comparison point...but instead the 20 years prior should be the expectation and hope. You can't hope to get the talent and leadership we had on that 97 team ever again.
I'm sure everyone has a losing record against the Top 5 in a 20 year period not named Alabama the last 20.
