I believe that you stated it best in of the previous incarnations of this thread when you said something to the effect of 'While IU may be considered the top B1G job, it's not
that much better than OSU. And the fact that OSU, as well as Michigan, Florida and Texas, are Football-first schools while still Top-Tier/Elite hoops jobs that allow a coach to live and work in a non-fishbowl environment. Thus, your spot-on point about OSU as one of the most appealing CBB jobs.
I don't believe that this is as true (and you can also say this about UNC, Duke, UK etc..) as 10-20 years ago due to a drastically differing CBB landscape. Given the proliferation of games on National Television (FS1, FS2, Several ESPN spinoffs and Big Ten, SEC, ACC Networks etc..) and the heavy use of social media, players and programs can promote themselves in a more expedient fashion today. And the fact that Markell Fultz from the Wahington Huskies was drafted #1 in "17 sent a clear message that one-an-done talent need not play for the usual one-and-done factories.
Using a non-IU example, as opposed to '07, John Beilein would have virtually zero need to jump to Michigan today to recruit top-tier classes, as the aforementioned elements at his disposal today would allow for him to assemble the Michigan-type classes in Morgantown. Fast forward to today: If you're Scott Drew, Chris Beard, Mark Few, Jay Wright etc and you've already built a top-tier National Program (with the exception of Few, in a major conference), you have no reason to seriously entertain any offer from another school, even if the offer originates from a school considered an Elite Job, other than to obviously utilize the outside offer to gain a raise from your current school.
Roy Williams jumping from one elite job (Kansas) to another (UNC) years ago - and basically because he had strong ties to Dean Smith and UNC - was the exception and not the rule.
