Were the games you watched from the beginning of the season, or the end of the season? I ask because there was dramatic improvement in Adams as the year went on. Ironic that you said he has no feel for the game, because his head coach said that one of his redeeming traits is that he has a good feel for the game, and thus his improvement. Considering that sometimes in New Zealand the only competition he could find on the court was his sister, its no shock that he's behind the curve.
Personally, I have no problem with the Kings taking a flyer on a potentially good player in the future, as long as they make some other moves through freeagency or trades. I've never looked at the draft as a quick fix device. It can be, if you get lucky and get the first pick in the draft and Lebron is sitting there. But I mostly look at it as a building block tool where you keep adding pieces, that in most cases, especially in todays NBA, need developement. Of course I realize that others see it in a different light.
Both games I saw were from the middle of the year, against Syracuse and against Louisville. The Syracuse game wasn't a great one for Adams and was an even worse one for Michael Carter-Williams. Adam's numbers were about the same agasinst Louisville but he played much better. Other than the free throws (he has an ugly motion) he played within himself pretty well. If I wasn't watching him specifically I don't think he would have stood out, but he played a pretty efficient game.
To me Adams looks like what he is - a very raw newcomer to basketball who is trying to apply fundamentals that he's being taught but doesn't yet have an intuitive feel for the game. As I said previously, he looks like he decides what he's going to do with the ball without regard for how his man is playing him. He also gets himself way out of position defensively, especially on pick and rolls.
Now, it may simply be that Adams was incredibly raw and HAS come a long way quickly. If so, maybe his learning curve is great enough that he'll contribute sooner than I think. But I can just go on what I saw watching him play and that's a big man with a nice frame and mobility who has some bad habits and no real offensive game to speak of.
