I completely disagree with this assertion, and I think Casey Thompson is a good example. His play to date is pretty consistent and is much closer to his ceiling than Sims.
Sims, on the other hand, has phenomenal tools. His potential is as high as anyone in the country, but he hasn't played at anywhere near that level. You see this play out in those projections above, Sims is much higher in most of those sets despite the fact Thompson's production over the past two seasons is significantly higher.
