I agree with
@htownkidd. Although I think he should, in an ideal world, be moved into the box, I think he has no desire to bang like that. He likes to ball hawk and be the last line of defense, and to be a playmaker from deep.
Compare it to a guy like Kevin Durant. In the 80s/90s, a guy that tall would be expected to play as a power forward, down low with his back to the basket. Obviously, that is not true today. I think that is kinda like JW. We want him to be something he is not... at least in part because we all want to see JW, Tae & Kam play at once.
For better or for worse, it seems JW is a safety. I would like to see more physicality and consistency from him. As of now, he seems to want to be more of a splash play guy - look at the way he tackles... always trying to strip the ball, almost to the level that it looks like he is acting. Now, there's nothing wrong with wanting to strip it, but not at the expense of laying the wood and playing fundamental ball.
Still young though, and there is a high ceiling there. But he isn't an all-conference guy at this point.
