If you really want to train a player, you can get a better one for a couple of bucks. If you prefer training your own drafted players, he's trainable to become an SF. His skills/length are actually great for that because you only need to train guard skills, and short players train faster in those.
Train OD until 12, JR until 9, HA/DR until 11, PA until 9 and finish with some JS until he caps and you'll have a nice SF.
