It's weird how much criticism he gets when, in fact, Smart has been very good to great, and he's been much better than a lot of guys who were drafted ahead and around him - better than everyone but Wiggins, arguably.
Most guys, even the ones who are solid defenders in college, are bad defensively as rookies. Smart was an outstanding defender last year, not only compared with other rookies. If Smart were that good offensively, he'd be averaging 20ppg on high-40s shooting and everybody would be calling him a future hall of famer. Meanwhile, guys like Randle and Parker would be putting up ghastly shooting numbers and everyone would be calling them busts.
Instead, Smart has been a mixed bag offensively, but there's a lot to like for a guy whose primary calling card is his outstanding D. I totally disagree with the characterization that he shoots too many 3's. He is shooting a high volume of 3's and making almost a third of them. That isn't awesome efficiency, but it isn't troublesome, either; if he bumps his pct up from 32% to 35%, which would be very modest, then that shot becomes a clear positive for the team. It's easy to see him getting to around 38% on slightly higher volume, which would make him a very good shooter.
I'm much more concerned about his 2p%, which is 41% on poor volume, and his free throw rate, which is lower than expected from college performance. The narrative entering the season is that his ankle injury hampered him from driving aggressively to the hoop, and it remains to be seen whether he can be more aggressive once he is fully healthy.
