This guy could be a key centerpiece for your team and still be salary efficient and cheap. SFs are the cheapest position in the game and my opinion on how to train him to start off will help you out and keep him cheaper. He is a bit behind some of the other guys, but there is still no harm in training him. Obviously it is ultimately up to you and what you want to do, but I think he is a great player to train up.
