Michigan has 5 times the population of Nebraska. Not only are there more good players there, but for the rest of you life after college you are connected and looked after within a much bigger economy than Nebraska's. Michigan is also one of the best state schools in the country - a degree from there carries a lot of weight.
How many kids dream of living in Nebraska after they graduate? How many dream of living in Southern Cal, with a population 25 times Nebraska's? Florida 22 times? Ohio 6 times?
If I was the parent of a four star player living in Indiana, who had an offer from Michigan and on offer from Nebraska, my advice would be to head north, not west. We have some things to offer, and we have a shot with a certain kind of kid. We can and generally do make the most of that.
But Michigan has a lot that we don't have. We may as well realize that.
Edited to add: And you mentioned Stanford too. 95% of kids from anywhere except Nebraska who would choose Nebraska over Stanford, unless they plan to study agriculture, are being poorly advised.
