Have to laugh at all the Husker hating.
News flash: Iowa State, if invited to join the Big Ten, would have left the Big 12 too. In a second.
The difference of course is that Nebraska had the power and cache at the time to improve the Big 12, but they took their ball and went home. Mostly because Osborne had too big of an ego to work with Dodds.
ISU has never had that kind of clout, and pretty much the whole site save for you knows it. If Nebraska turns down the Big 10 back then, we'd likely still have the Big 12 as it was, and the idea that it was a step down from the Big 10 would be laughable.
