The TCU Def coord may not fit the age profile for our Head Coach, but he certainly has an excellent track record. TCU has led the nation in defense the past two years. They compete on a very high level, and they don't have SEC type talent. I like the Boise Off Coord, or the OK State off coord, just to name a few. I would check and see if they have any interest, maybe they do, and maybe not. I would not shy away from including them just because they are Coordinators.
Another point, there aren't any programs below us in FBS. So, we can't hire the guy that took a bad FBS team and showed how he made them great. There aren't any programs that are in a similar situation that we have. We are the bottom. We can only go after FCS head coaches, previous FBS head coaches that were canned for some reason, or Div II head coaches. None of these have our set-up, so it's impossible eliminate the risk.
