I've joked about Nebraska reaching MInnesota status in the past but those were just jokes. While the glory days are probably going to be hard to match in the future it doesn't mean they're completely out of reach, all it takes it the right set of conditions to arise. We've seen that recently with ND, FSU, and now maybe Washington. Granted those are just single seasons but I digress.
Nebraska won't become Minnesota, the space between the programs is too large. You're just going to have to come to grips with the same reality that almost everyone else is living in with the state of college football today; with the conference restructuring and evolution of the game it is very very hard to build dominant programs...there's really only one in the entire country and that's Alabama. The days of the domination you saw in the Big Eight will never return, you have too much competition. Penn State, Michigan, and Ohio State are in the same boat. The days of Ohio State just strolling through the conference only sweating UM are loooong gone. They were reminded of that two weeks ago. Your pining for something that you'll never get not, and that isn't because of some failing on you're part, it's just damn near impossible. Settle in to the new status quo, you're going to have to fight for every game. There's more parity. Everything is more competitive and it is much more fun this way.
