The issue for Nebraska now is --- they no longer play in the Southwest. When they played in the Big 12 -- they could recruit Texas well, as those kids grew up watching the Big 12, they know about the big rivalries and who the top teams are.
Now -- kids in the Southwest watch little to no B1G football. What they do watch are the top games like OSU/Michigan, OSU/PSU, Michigan/PSU -- the games with a national audience. They couldn't care less about watching Iowa/Nebraska, Wisconsin/Nebraska -- their rivalries are now regional rivalries.
So if a top recruit from the Southwest wants to play in the Midwest -- it is going to be at................Ohio State. If there is ever a kid whose family puts academics on par with football, Michigan can get that kid, like they did with Daxton Hill, Jabrill Peppers, Donovan Peoples-Jones, Rashan Gary, etc. Those are the top recruits we get.
