The sample size is still very small. In the 17 games since the all star break, he's making less than 2 FG, less than 1 3FG and less than 1 FT per game.
But the trend is encouraging. In those 17 games, he's basically been an average shooter (league averages .460/.363/.768), which is a significant improvement over his pre all star shooting numbers (.379/.317/.560).
He's still a long way from being a significant offensive contributor, but given his age and his defensive chops, you'll take anything you get from him on the offensive end as a bonus.
The most encouraging thing is that when he does shoot, he shoots without hesitation. That shows he has gained confidence and trusts that the coach isn't going to pull him out of the game if he misses a couple shots. He's earned his minutes with his defense. The offense will continue to improve as he gains experience.
