Young had better D-League stats as a (younger) rookie, so he is arguably beginning his career arc from a higher starting point than Jones. He has also whiffed in fewer opportunities, so he has fewer strikes against him, which leads to having greater future trade value. If Young proved he was hot garbage last season, then PJ3 proved that he was even hotter garbage in almost twice as many NBA minutes.
You are massively overrating the value of "freakish physical gifts".
