Not sure I agree with you. Chadwell is the only person I've even seen mentioned that runs a unique scheme and I don't think he's going to be coaching at Nebraska.
There was a small run on hiring out of the Briles tree (Dino Babers, Sean Lewis, Montgomery at Tulsa) and Briles was part of a run out of the Leach tree but Nebraska's never really gone after scheme in hiring. You can make the argument that Riley was a scheme hire but I don't think that's a very strong argument given the conflicts with Bo weren't based on offensive scheme. Not like the perimeter west coast was novel.
I do agree with your point about Nebraska being design-build, so let's take a look at the design-builders on the market. These are guys who've elevated poor programs steadily and consistently. Most have done it more than once. A lot of these guys have had their names tossed out there:
- Matt Rhule (Temple, Baylor)
- Bill O'Brien (Penn State)
- Matt Campbell (Toledo, ISU)
- Lance Leipold (Buffalo, KU(?))
- PJ Fleck (WMU, Minnesota)
- Chris Petersen (Boise, UW)
- Chip Kelly (Oregon - with $ome help)
- Dan Mullen (Miss State)
- Lane Kiffin (FAU, Miss)
- Mark Stoops (UK)
- Bob Stoops (OU)
- Mike Leach (TT, Wazzu)
- Bill Snyder (KSU)
- Mike Gundy (OSU)
- Pat Narduzzi (Pitt)
Most of these guys are great teachers and good schemers who steadily improved the quality of the product. A few of these guys are promoters who brought in fans and improved the brand (Fleck and Kiffin, Gundy to some extent). Nebraska needs the former, obviously the brand is all that's left. Outside of these names, most of them worked under a great coach themselves as a younger coordinator. Very few, if any were established P5 coaches when they arrived at their last stops. Leach and Petersen being the two best examples.
A lot of people are overlooking Jim Leonhard here but I see a ton of Bob Stoops in him and I think he's got the elite teaching skills which show up in his development and on the field every week. Probably the best DC in the country and possibly one of the best true coordinators. Look at Aranda, not only are there real ties between the two but watch an Aranda coaching clinic, the guy is a college professor. Same goes for Pete Golding but I don't see him getting a real look. Fantastic teacher. Muschamp has that same teaching ability but wasn't a great CEO.
