Patience in recruiting, competing and so on is the order of the day (or years really). Riley is NOT going to transform Nebraska football from a perennial top 35 or 40 program into a top 10 program by merely showing up. Urban Meyer could not restore the natural order of the Huskers 'on high' over night. It would take several years minimum for a top of the heap coach of his status to do it. Riley will restore our reputation as a good place for parents to send their kids to play major college football. Then he will have to gradually improve the product on the field. It could take 5 years realistically to get us into the perennial top 20 status frankly.
Some of what you say has merit, but i disagree with the quoted. If you put Urb or Sabs in Lincoln, he would instantly pull top 10, heck top 5 classes.
Also, for all of Bo's faults, from most accords he represented the university very well when he was in living rooms.
