Why would anyone put any stock in lists of candidates generated on a bulletin board? Posters might accidentally guess some candidates right, but would be clueless about other viable options.
And by "other viable options," I'm not talking about a celebrity wish list of who's who -- I'm talking about established coaches from other levels [G5, 1AA, etc.] that 99.9% of the posters probably have never heard of.
Timing will be a factor, as well. Nobody knows when JB is going to eventually step down [or worst case, be "coaxed" into retirement]. Coaches that have homes today aren't going to come forward to express public interest about a job vacancy that isn't open.
We also don't know what other programs -- if any -- we'll be competing against when our position opens up. That could work in our favor, if we are the most attractive program open when the time comes -- or potentially work against us, if several other high profile jobs are simultaneously looking to fill vacancies.
I'm also highly confident that JW is maintaining a list, that is probably constantly fluid, based upon the changing dynamics of the profession, people taking different jobs, etc. And that said list will be further refined with external input from the proper industry channels when the time comes.
As for NIL -- times have changed, you are correct. And it's time for our program to get with the times to avoid being left behind. Roy Williams retired rather than having to deal with it. If we aren't going to actualize the potential for prospective recruits from an NIL standpoint, then things will continue to slip until we bring somebody in from outside the current program who WILL.
