Not sure what you are arguing with regards to my post. I saw Powell in HS at Joliet a few times. He was really a SF who occasionally played PF. I also saw him in a few practices early in his career, with Self as the coach. He was indeed raw. He wanted to play 3, actually was not happy he was not getting more utilized at the position, I know for a fact that his family (his father) was not very happy either.
As an upperclassman with Weber, he convinced himself to make the transition to PF. I assume he realized he was not going to get much PT otherwise, give the team roster, style, composition. He bulked up, although Roger was always physically fit, even when he arrived at UI as a freshman.
Posters on this thread have implied that Black can make as similar transition to SF, if Roger could do it, so could Black. Others have implied in response that maybe Roger was more talented. I do not agree with either, I just think that Roger's transition was a lot different transitioning from SF/PF in HS to a PF role in college, whereas Black is more of a traditional PF style of player who would need to transition to SF, which I do not think it will happen either. Not because of talent, but skills-set, totally different skills-set required than Roger's. And a much more difficult transition.
