Nebraska should start the best intramural football program in the country as an in-house farm team (but outside the Athletic Dept), give out scholarships to players who used to be the ones from 85 to 105, hire high quality developmental coaches but completely separate from the intercollegiate team, etc. Recruit the same highly motivated, team-oriented guys we find as walk ons today.
NCAA and these lawsuits are all confined to intercollegiate Athletics and I'm fairly certain as long as it remained intramural it would be hard for them to regulate.
Take the best of the players from the intramural teams onto to main team when we need them. Would we lose some players to other teams? Yes, but if we selected for in state, 500 mile, and grateful personalities who understand and appreciate Nebraska's historic commitment to walk ons, I think in many cases we would have first option on the best talent.
Strive to make it complementary to lower level schools and to develop and maintain strong relationships with those as another pipeline.
