An Urban Meyer or a Nick Saban could definitely recruit to Nebraska, sure. I believe they could average top-10 classes.
Trouble is. An Urban Meyer and a Nick Saban aren't going to take a job at Nebraska, so that doesn't really matter.
Scott Frost might be our only good shot at being an elite program ever again. Think about it - the two coaches responsible for Nebraska football being what it is were Devaney and Osborne. Osborne is a small-town Nebraska kid, born and raised, and Devaney lived in a world that looked a lot different than the one in 2017 - a world where it was a lot easier to be successful and content in a profession like football coaching in a place like Nebraska. We have never really had any history with 'mercenary' coaches, and the odds are very much stacked against us that if we ever offer truckloads of cash to someone that would be considered an 'outsider', that they'll either fail, or they'll leave the second an easier opportunity comes their way.
