Don't kid yourself. Penn St. and Michigan are top 15 jobs, arguably top 10. MSU has never been a top 25 job and probably never will be, although we may pay a top 25 salary.
I would say we're a top 25 job unless you discount the money once you get over say $2M a year.
There's a huge grouping of jobs once you get out of the blue bloods and almost blue bloods (like say Auburn) where they don't have advantages of a blue blood but a good coach can win. Basically every non-blue blood SEC coaching job other than Vandy, UK, and Arkansas (depending on whether you think their drop off is due to a change in recruiting landscape or just several bad hires) are pretty close. Va TEch, UNC, Miami, Ga Tech, maybe Virginia and NCSt are all in that grouping or close? Ok St. Tcu and Baylor? Just comes down to personal preference on those jobs. Some are a little better positioned, but not a major difference for the most part.
Lots of ways you can judge jobs though. I would prefer a job in an easier conference with less crazy fans and less money with hopes that I would coach longer and enjoy it more. But if you are coach worried about your legacy, and every head coaching job will make you a multimillionaire and make it likely you will become a decamillionaire if you have a little bit of sustained success, then maybe what's most important is a job that will give you the best shot at the playoffs.
