University of Nebraska - Kearney. I don’t think a true D1 football experience will happen anywhere not D1, but their football team has gone from awful a couple years ago to pretty good. The whole community is pretty supportive and follows the team pretty closely. Wrestling may be a tougher admit though, they get a lot of guys right on the cusp of D1. If you PM me details about his abilities and successes I can probably give you a good guess of whether this is worth pursuing.
Clarion, Davidson, Sacred Heart, Franklin & Marshall (DI for wrestling only for some reason), Long Island U, and much of the Southern Conference (except Campbell) have a lot of D2 and D3 talent on their rosters honestly. If any of them are fits academically and socially he could contact their coaches. I don’t know anything about their football programs, but they are D1 except for Franklin & Marshall.
I feel I should clarify that there is some talent on those rosters, but overall those teams tend to not field a full roster with kids who can realistically hope for a winning record in D1. I know a kid at one of those schools who was a low D2 recruit otherwise, but the school fit and I think he probably got a de minimus scholarship just so he could say he was offered a scholarship. The coach took him because he was essentially a free athlete.
If you have questions about specific wrestling programs you can PM me, S ended up D1 but I know quite a bit about the other divisions and some of the other coaches, D2 in particular. S is in college now, but I still follow the recruiting pretty closely, and most of the kids I know end up D2 or NAIA so I know those programs pretty well. D3 a bit less, although S had some feelers out there in case D1 didn’t work out.
