Nope.
I'm still really, really high on Exum and agree with Lindsey's comments - he has all the tools, including the intelligence, work ethic, and selflessness; he just needs to get stronger. We laud Gobert for the impact he had after the All Star break, but frankly the team's turn around started weeks before when Exum was swapped into the starting line-up. It means something that even when he wasn't playing well individually, he helped the team to win.
Dante has three weaknesses currently:
1. A lack of ball-handling ability, particularly with his left hand.
2. A lack of strength and conditioning.
3. A lack of finishing/mid-range.
And what people call his lack of aggressiveness isn't actually that - it's the culmination of the above three factors combined with Dante wanting the team to win. Lucky for him, the Jazz, and us, those three factors are entirely teachable and solvable. Everything that can't be taught, Dante already has in spades. (Side note: the biggest knocks on Jordan, at 20 years of age, was ball-handling ability with his left hand and his shooting - both were solved. Not saying Dante is the next Jordan, but even the GOAT had concrete skills that held him back early on in his career.)
I've been saying for the past year that PGs tend to make a minor jump between years one and two and then a major jump between years two and three. As long as we see minor to moderate progress next year with him, we're in a very good position. At this point, I think Dante's floor is Hayward with better defense. But I'd easily drop down a bet that he'll be a multiple All Star.
Whether he becomes a superstar or not, I'm unsure of, but the potential is very much there and this year didn't do much to reject that possibility.
