Firing a bunch of coaches and starting over for year 3 might work, but I think we can admit it's not a great sign overall for Rhule's tenure. Coaches who make it traditionally make steady forward progess and don't have to hit the reset button after two years. They don't have to go searching for answers, and bring in eyes on the program to tell them what to do.
At this point, I will be fairly surprised if this turns around to end in 10 win Nebraska teams under Matt Rhule.
Sure hope you're proven wrong, but I can't disagree with your logic.
