Just looking at it from an on the field issue (as I know Nebraska has gotten a lot of off the field rewards for being in the Big 10) do the Huskers need to try to get back into the Big 12? Nebraska is never really going to be able to compete for recruits with the top tier programs of the Big 10 as like it or not Nebraska is stuck in the middle of nowhere and despite having a couple decades of great success they still don't have the history that many of the teams in the Big 10 have. Also when they left the Big 12 they fell off the radar of many of those Texas recruits that would see them play when they were playing Oklahoma and the Texas schools. Now instead of being one of the main places the Texas highschool kids think about going they are one of the last Big 10 schools kids think about going. No matter what opinion you have on the Big 12 matter you can't really get around the fact that Nebraska had better teams when they were in the Big 12 than they have had since they left.
