His catch and shoot form looks better. Still likes to fall down after taking pull-up threes, but I guess that's just a quirk of his. I think he'll always be streaky when he's creating his own shot, but I'm confident he'll become a solid off-ball shooter.
At least against the competition in summer league, he looks a lot more confident and composed dribbling through pressure and making passes out of the pick and roll. Seems to be finding a good balance between taking shots and creating for teammates.
The interesting thing to see will be whether he continues to diversify his shot selection, as he has done in summer league, when he's playing with the starters in games that matter. Last year he seemed content to mostly defer and just try to operate off the ball.
