Yeah.
Nebraska belongs with Army, Minnesota and Harvard in terms of teams that had a period of dominance but that might as well be a different universe now.
Minnesota has a greater chance of becoming a top 3 program again than Nebraska does, and they have almost no chance.
Princeton is still the all-time leader in national titles claimed with 28. Yale is second with 27.
Alabama is third with 23. Assuming the next guy (Dabo?) can replicate what Saban has done (six so far) they could conceivably pass Princeton in some of our lifetimes.
Other fun ones towards the top of the list...
12 = Harvard
11 = Nebraska
11 = Pitt
9 = Minnesota
