Just for the heck of it I looked at the consensus rankings from the high-school class of 2017, i.e. players who would be college seniors this season.

The highest ranked recruits still in college are Washington's Quade Green (23), FSU's M.J. Walker (24), Louisville's Malik Williams (25) and Xavier's Paul Scruggs (29).
We also have some players well outside that range who have developed into major stars. Likely NPOY Luka Garza was ranked 93. But we also have West Virginia's Derek Culver at 79, Stanford's Oscar Da Silva (98) and Davidson's Kellan Grady (82) among others.
Corey Kispert was not ranked in the top 100.
Nothing earth-shattering, of course. Guys in the top 20 or so don't stick around for four years and some real gems can be mined outside the top 50.
But, just hypothetically, had Duke brought in a class of just Garza, Kispert, Culver, Da Silva and Grady, we would have thought K had lost his touch.
