As long as the portion of the fanbase that thinks they should be on Alabama/Ohio St/Georgia's level exists, it will eventually poison the rest of the fanbase with a small amount of success. If Rhule (or the coach that follows him) gets Nebraska back in the conference title/CFP mix, eventually he'll get canned unless he's bringing home titles and CFP wins because he "can't get them over the hump."Rhule will make Nebraska a very good football team but they will never be elite like the past. Part of that is because they were at such a high level it's impossible to repeat that in any conference except the SEC. Even in the SEC there's only 2 teams capable of being what Nebraska was. There is a fan base that expects that, but that base is actually very small. Most of their fan base just want to start winning again and the support for a team that hasn't been to a bowl in a decade is actually pretty amazing. I think Nebraska is in a pretty decent spot. I don't think the Big 10 is invincible even with the top of the PAC.
Pilini was a weird case because he was a fantastic *******, but was also justifiably upset that 9 win seasons with conference title game appearances landed him on the hotseat. Maybe a coach with more tact would have managed to stick around, but plenty of the fanbase seemed very eager to push him out.
