I agree he looks very unappealing right now. But I you train him solely on one on one and ball handling for one full season, I think he will be a very promising 19 year old. And his salary won't rise much, either. Just don't train his JS or Rebounding until you have a complete SF, and from then he can have a breakout year training his primaries.
