Years ago we relied a great deal on players from Nebraska, Iowa and other Midwest states and picked up a few skill players from Texas, California, etc. Now we rely on getting most from states outside of the Midwest. Not easy to recruit kids from the South as a different culture. Lot of big money in the SEC area. Who knows what college football will look like 5 to 10 years from now.
In the glory days there was consistency where the NU coaches encouraged Nebraska high schools to run the option. Nebraska kids were more likely to be doing farm labor instead of sitting in a machine all summer. This meant huge kids were also really strong and fit. Rural populations have shrunk or at least are not growing the same as urban, high school football in rural areas has become less popular, and more expensive, and the national circuit more important to development.
Nine of eleven offensive starters from the last national title were from Nebraska. If that is a necessity to us winning, we will never win again. Scott Frost, Ahman Green, big, strong oline from Nebraska, running a high-powered offense just isn't ever happening again. Unless...Florida is flooded and people move here.
