Or just stay with Big 10 examples. Purdue and Minnesota came from the cellar to be relevant (and favored over Nebraska). Maryland hired a new coach who took them from 3-9 to 7-6 and a bowl win in two seasons. Indiana's Tom Allen has two more bowl appearances than Scott Frost in the last four seasons. Even Rutgers has had its moments, and with Schiano back they have reason to be more optimistic than folks in Lincoln. Illinois hasn't had much to crow about, outside of beating Nebraska.
Most of these schools are cold weather, small midwestern towns without traditional recruiting advantages or recent legacies, with lesser facilities, fanbases, budgets and opportunities for non-salaried coaching income.
It's really not entitlement or arrogance to ask that Nebraska field a better team than the worst teams in our conference, although it is self-loathing to think a good coach and skill players would never come here.
