I would not train him as SF. OD is atrocious, and it will take forever to bump that up to needed levels.
Train him as a PF or C, even though height is not that great. With HOF potential, you can really train up the inside skills. To begin with, you may want to train the outside skills in the first year. With OD, I would personally not focus on it that much even if you do wanna train it up.
