I wouldn't worry about Smart, in his prime years he is going to be a very good player. He is still recovering from the high ankle sprain, that injury lingers for a long time. I bet he won't be right for several more weeks.
My only complaint with Smart right now is that he seems to be thinking about playing PG and running a team than just playing basketball. I would love to see him start attacking the rim, I think we well see that once he is over the ankle injury.
Things I love about him so far, his defense is great, he is actually a better passer than I thought and he seems to have a great attitude. I think the Marcus Smart we see in February, March and April will be much different than the guy we see now...
