Hey mate :)
I don't agree with few things about your build. First off, he is starting with low JS, so I would build him as a center, not PF. It would waste too much time to bring up JS.
Second, I don't like the 16/16/14/10 build. In my opinion, rebounding needs to be the highest skill for centers. Also, he should think about higher shotblocking, especially since they decreased the cost of it recently.
