I've seen NN play 3 times. He is a dominating force on defense. He shuts down the paint. After he blocks 4-5 shots in the first 6-8 minutes teams stay out of the paint. He has a great sense of timing and he doesn't commit fouls. Raw offensively but very coordinated. Seems a lot like Anthony Davis. If it's true that he is going back to UK for another visit, that probably says it all.
