I have a valuable starter potential player I trained on my USA IV squad. If you are training him to sell, probably not worth it but I get some good value out of him. Not gonna post his skills in case opposing players are watching but if you make a well-rounded player he can be a great 6th man even in DIII.
My guy starts at SF now, but can play PG-SF depending on tactics. Always useful to have a versatile wing player, imo.
