I don't think its so much a Nebraska thing. The rules on visits are so loose now compared to 5-10-15 years ago where you can take more officials, see more places in the country, and be wined and dined, which everyone loves. Then you can take unofficial visits to see the gameday atmosphere, and with NIL being what it is now that doesn't seem to be a preventative cost for kids to do that. I'm not terribly keyed in on the recruiting process and the inner rules that say what can be paid for on official/unofficial visit, so I could be speaking out of my ass, it just seems like way more unofficial visits are happening.
Camps are interesting and I think its crazy that, at least here in Nebraska, we haven't really seen them the way we're seeing them right now. Rhule is such a detail oreinted person that getting a kid in here to see him work and train allows the staff to kind of push aside the stats/measureables and look at a kid who came in here worked hard, has a good frame, was coachable and really envision what your state of the art training and your innate belief in your development can do for a kid that I'd put money on the coaches being more sure of the culture fit on Hoffken than a talent thing. Now again, it helps the kid has the size and frame plus raw physical talent but without getting him in to a camp and seeing how he works, its hard for me to see an offer coming his way.
Either way I think the way things are shifting here is kind of how the rest of the country has operated for a bit and we're modernizing under a well connected, hard working coach who never stops evaluating, relationship building, and otherwise looking for ways to make his job more efficient, likely so he can just simply do more.
