Gobert as a top 20 player. You added a seventh that had him at #24. I could easily go add several more, but just for fun, here are four more. Again all top 20.
So we are now at 10 composite performance stats that show him as a top 20 player, and 1 that shows him at 24. But you're point is somehow proven because sometimes some stats have flaws and you did your own eye test. Singular stats have flaws, but when you aggregate many quality statistics together and they overwhelmingly point to Gobert as a top 20 player, then you probably need to reexamine your own personal bias of his value.
