I had been hoping to see a little more Baron Davis in Smart - a cannonball who can get into the lane and has the strength to finish or draw hard contact at the rim. We certainly haven't seen that. It's a bit surprising to me, because he has such great quickness and footwork on the defensive end of the floor. I'd like to see him take the ball to the rim more, but I'm worried that he just might not have the ability to beat guys off the dribble.
On the plus side, his shooting has been a pleasant surprise, and his shot mechanics look fine to me. His jumper definitely isn't broken, and it's reasonable to expect it to continue to improve. If he can become a 35% three point shooter, with his defense, he's a rotation player on a good team. And the defense, my goodness. He can defend either guard position, he has great hands, and he seems to grasp NBA defensive schemes. He fights through picks better than anyone I can remember watching recently.
I also think he is actually a point guard, which bodes well for his long term NBA future. He can be a bit careless with the ball at times, but his handle is fine -- he's no Avery Bradley. He can make all the necessary passes, and he's really improved that little pocket pass off the pick-and-roll. His decision making needs to improve, but the skills are there. I'd say actually he looks pretty much as advertised: NBA-ready defense, offense a work in progress. Likely rotation player, possible starter for a good team, but unlikely to be a primary or even secondary offensive option. That won't save the Celtics, but it's a valuable piece.
