It's not the 9 wins. It's the zero conference championships, the embarrassing losses almost always televised on national tv, the losses to inferior talented teams, the lack of knocking off a top team. And lets be honest, Nebraska's had the luxury of a soft division both in the Big 12 and now.
I think they said the same things about Alabama for years. Then they go Saban. It's about getting the right fit.
The ONLY team in the Big Ten with hands down more talent than Nebraska is Ohio St. They are not being outrecruited by Minnesota, Wisconsin, Iowa, Northwestern....nor Michigan State for that matter. Yet they lost the last two to Minnesota and Michigan St, struggle to beat Iowa, need miraculous comebacks to beat Northwestern, get boat-raced, twice now, by a Wisconsin that doesn't throw because it can't. I only need point you to Michigan State. In the last 5 years, two 11-win seasons and 1 13-win season. North Dakota State three-peated when everybody said no northern team could win the FCS. The expectations aren't unrealistic. Nobody is expecting to repeat the 5 year run of the 90's. They just want a team that doesn't beat itself (like Pelini's turnover prone team...all 7 years) and can actually win the conference and every once in a while a chance to get into a NC. 10+ win seasons? It can be done. It's being done at other places with a lot less resources, because they have good coaching. Consider that Nebraska has a 1st time HC, DC and OC......that's too much cutting teeth.
