Play him in whatever position suits your training routine.He is actually a very, very good rookie and you could have one of the best SFs in the country if you train him correctly and be almost a lock as a future NT player.I would recommend single position training for him and training Outside Defense and Jump Range for this season as those are two of the slowest skills to train (because they can be 2 of the most important) so best to train those while he is still young.
