Nebraska was for quite a bit of time a lot more than what Clemson has been recently.
It never ceases to amaze me how short some memories are. Where was Alabama for the little more a decade and a half leading up to their hiring Saban? There are a handful of places where one quality hire is all it takes to become a near dynasty, regardless of how mediocre the recent track record has been, Nebraska is one of those places.
COVID restrictions aside, they've sold out every home game going back to when JFK was still alive. They made the mistake of bringing in an all style, no substance AD (Pederson, about 17 years ago) who thought it would be a good idea to overhaul the way they did everything. Once they moved on from him, they brought in a head coach who was building the program pretty well but ended up being almost as nutty as Diaco.
It may take another hire or two before they get the right head coach (hell, not quite 25 years ago Bama had to fire their new head coach before he ever coached a game for them because cops found him drunk in a motel room with a stripper) but their tradition and fan base would be sufficient to keep almost any successful coach. Few schools can do that.
