Is UNC the #1 job in mens basketball?
An objective thing but you'd have to think it's top 3 if it's not a clear #1. Just the fact that Roy left KU for the job shows you it's kind of an elite job among elite jobs.
I wouldn't use that as why the UNC job elite. Williams was a longtime UNC assistant before he left to coach at KU (remember, Williams went from UN assistant to KU Head Coach. KU was his first head coaching job). I think UNC to Williams was one of those dream jobs for him that he was always going to go to if the opportunity came.
Not saying that UNC is not elite, because they are. But I wouldn't put them above KU. UNC and KU are on the same level in my opinion.
