I understand the sentiment of the article, and the criticisms are valid. To add context, FWIW, Hoven has added people to the team, one of which is focused on the analytics portion. I like to take a hybrid approach when analyzing players - and my focus is on prospects anyway. But the overall point is, looking at some metrics, he should eventually start putting up more points by sheer virtue of taking closer shots and generating rebounds with his attempts.
I don't completely agree with the conclusion, but it's important to call out the points the author is trying to make.
I'd be very wary of this level of speculation, and there's no evidence of this. There are several other possible explanations that are less libelous but all equally unprovable at this point.
