"Nebraska's move to the Big Ten has not helped its recruiting at all. If anything, it has hurt quite a bit. The two-year drop of 28 percent compared to the '11-12 classes is one of the biggest in the country, and coach Bo Pelini's perpetual hot-seat status doesn't help either. Nebraska is a weak state for high school talent, and Nebraska has not been nationally relevant in any way since current recruits began elementary school."
This is from an article written in 2014. Our recruiting hasn't improved since then.
We are an outlier in the conference... the team furthest away from the center. The worst part is that the B1G conference put us in a division (west) with other teams that are mostly bottom dwellers. The conference did us no favors in doing this. Our division is routinely called the worst division in the power 5.
Teams in the other division (east)... Ohio State, Michigan, Michigan State, Penn State etc... geographically have access to the recruiting hotbeds within the conference and players recruited will know that their families can watch them play.
All of these things should be something to consider... and would be things that "Bill", great coach that he is, surly sees.
With that said I don't think we will return to the big 12. Too many ego's involved.
