It's honestly too difficult to rank them in order, because little things will push one over the other by an inch, depending on what a coach values. For example, it would be nearly impossible to objectively judge Illinois vs. Maryland ... they are SO similar in so many ways, and more intangible things like regional culture or family ties might enter into the equation.
However, I do think there's a clear top five in general, and it's below. I'd go with the following, breaking my earlier post about there being fewer tiers of jobs than this.
Tier One
Indiana
Ohio State
Illinois
Maryland
Michigan
Tier Two
Michigan State
Wisconsin
Purdue
Tier Three
Minnesota
Iowa
Rutgers
Tier Four
Penn State
Nebraska
Tier Five
Northwestern
(1) The top five jobs have proven to be able to have sustained success through multiple coaches, AND they are the most popular teams in their states. All have huge alumni/fan bases, and even if fan apathy within their states might kick in when they aren't good (Illinois or Maryland), there is not a preferred other team for fans that they have to overcome for support - compared to Purdue ALWAYS being just a notch below Indiana in their own state, even when they've been better than them for years. All five have a winning tradition, great facilities, wealthy donors and great instate recruiting.
(2) The Tier Two jobs have some things going for them, but I would argue they've been propped up by certain coaches
themselves doing extraordinarily well - if not in spite of the job's limitations, at least not because the job is especially well endowed to win quickly. Wisconsin's instate talent is lacking. MSU might take a clearer backseat to Michigan instate in the years after Izzo retires. I already touched on Purdue.
(3) Tier Three jobs are fine, and each has its pluses. Rutgers has a shockingly engaged/loyal fan base for how bad they are historically, and the theoretical potential with NJ and NYC recruiting is easy to see ... however, facilities/AD finances are kind of a mess, and institutional support for sports seems less organized. Iowa has a decent history, but the instate recruiting is awful, and facilities are "meh." Minnesota has decent instate recruiting and ZERO competition for it, but they're just really in a bad spot, with multiple pretty decent coaches failing repeatedly there.
(4) Tier Four jobs are difficult simply due to a lack of tradition to the point where a large chunk of those schools' football fans literally cheer for other teams (like Creighton or Villanova). The money from their ADs is always channeled toward football first (even more so than your average place), and while they should be better at basketball than they are, there needs to be a bit more "proof" to move up to Tier Three. I'll say this, though ... if PSU ponies up and convinces Shrewsberry to stay, they have an argument that the time's are changin' and they're Tier Three.
(5) Tier Five is Northwestern alone for a reason ... it's one of the hardest jobs in the Power Five. We all know the many reasons why.
With all of that said, the gap will be bigger/smaller for every coach. We've previously discussed how Big Ten coaches just don't seem to move intra-conference, but if I'm at an Iowa equivalent and a Wisconsin equivalent opens up, I do not take it immediately ... the perceived additional advantages I'll get in my ability to win big will have to outweigh all of the negatives of upping my family and moving and also the pain in the !!! of rebuilding.
