Focus on him exclusively. When you train him, make sure he gets 48-75 minutes a week. I recommend you make him into a big. For example, OD to at least inept (4), DR to inept (4), PA to inept (4). After you get those horrible skills a bit higher, I would start training his IS/ID/REB. One more thing: make sure to single-position train. The only skills you can't single-position train are JS, DR, REB, Stamina and Free Throws.
