I agree with Coach MK. His handling is bad, and his outside defense a nightmare. I recommend training 1v1 Forwards (or Guards, if possible) to increase his handling and driving to at least inept. Along with that, 1v1 Forwards also trains inside shot a bit. Next, I strongly suggest working on his outside defense until he gets to awful or inept. Since he is a big man, you don't have to train his JS and JR if you don't want to.
